Definitions
- the present invention relates to a method for predicting a therapeutic response to immuno-cancer therapy in lung cancer.
- Lung cancer is one of the most common cancers in both men and women.
- non small lung cancer is a kind of epithelial cancer (carcinoma) and refers to all epithelial lung cancers, not small lung cancer.
- non-small cell lung cancer occupies a high proportion in the overall incidence of lung cancer.
- non-small cell lung cancer is divided into several subtypes according to the size, shape, and chemical composition of cancer cells, and typical examples include adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
- Adenocarcinoma is found in the outer region of the lung and tends to progress more slowly than other lung cancers.
- Squamous cell carcinoma starts in the early version of the cells that make up the airway, and shows a high incidence mainly in smokers.
- large cell cancer can develop in any part of the lung, and its treatment is still a challenge because the progression rate is fast enough to be similar to that of small cell lung cancer.
- Non-small cell lung cancer may include persistent cough, chest pain, weight loss, nail damage, joint pain, and shortness of breath.
- non-small cell lung cancer progresses more slowly than other cancers, it rarely shows symptoms in the early stages. Therefore, early detection and treatment of non-small cell lung cancer is difficult, and it is highly likely to be detected after metastasis to the bones, liver, small intestine, and brain. Accordingly, at the time of diagnosis of non-small cell lung cancer, more than half of the patients are advanced enough to not be able to perform surgery, so early treatment is difficult in reality.
- radical resection is performed, but only about 30% of cases in which radical resection can be performed. Furthermore, the majority of all patients who underwent radical resection appear to recur and die from a more aggressive disease after surgical resection.

More specifically, PD-L1-expressing negative patients may respond to PD-1 blockade, and PD-L1-expressing positive patients may not respond to PD-1 blockade. Furthermore, some responders without PD-L1 may have a similar response duration if they were PD-L1 positive in the Checkmate 057 trial. Moreover, PD-L1 expression is dynamic and can change temporally and spatially. This change in PD-L1 expression may be adaptive immune resistance exerted by the tumor.
- biomarkers for predicting therapeutic response of PD-L1 blockade CD8 T cell infiltration, inflammatory tumor markers, T cell receptor clonality and somatic mutational burden can be used.

Abstract
Description
본 발명은 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법 관한 것이다. The present invention relates to a method for predicting a therapeutic response to immuno-cancer therapy in lung cancer.
폐암 (lung cancer) 은 남녀 모두의 성별에서 흔히 발생하는 암 중 하나이다. 폐암 중에서 비소세포성 폐암(non small lung cancer, NSLC)은 상피성 암 (carcinoma)의 일종으로 폐소성암(small lung cancer)이 아닌 모든 상피성 폐암 (epithelial lung cancer)을 일컫는다. 이러한, 비소세포성 폐암은, 전체 폐암의 발병률에 있어서 높은 비율을 차지한다.Lung cancer is one of the most common cancers in both men and women. Among lung cancers, non small lung cancer (NSLC) is a kind of epithelial cancer (carcinoma) and refers to all epithelial lung cancers, not small lung cancer. Such, non-small cell lung cancer occupies a high proportion in the overall incidence of lung cancer.
한편, 비소세포성 폐암은 암세포의 크기, 모양 및 화학적 구성에 따라 몇 가지 하위 종류로 나뉘며, 대표적으로는 선암(adenocarcinoma), 편평상피암(squamous cell carcinoma), 대세포암(large cell carcinoma) 등이 있 다. 선암은 폐의 바깥부위(outer region)에서 발견되며 다른 폐암보다 천천히 진행되는 경향이 있으나, 초기에 높은 전이 경향을 보이고 또한 높은 방사선 저항성을 보인다. 편평상피암은 기도 (airway)를 이루고 있는 세포의 초기 단계(early version)에서 시작되며, 주로 흡연자에게서 높은 발병률을 보인다. 나아가, 대세포 암은 폐의 어느 부위에서나 발병할 수 있으며, 그 진행속도가 소세포성 폐암(small cell lung cancer)과 유사 할 만큼 빠르기 때문에 그 치료는 현재까지도 난제로 떠오르고 있다.On the other hand, non-small cell lung cancer is divided into several subtypes according to the size, shape, and chemical composition of cancer cells, and typical examples include adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. have. Adenocarcinoma is found in the outer region of the lung and tends to progress more slowly than other lung cancers. Squamous cell carcinoma starts in the early version of the cells that make up the airway, and shows a high incidence mainly in smokers. Furthermore, large cell cancer can develop in any part of the lung, and its treatment is still a challenge because the progression rate is fast enough to be similar to that of small cell lung cancer.
이와 같은 비소세포성 폐암의 증상으로는 지속적인 기침, 흉부 통증, 체중감소, 손톱 손상, 관절 통증, 호흡의 단기화(shortness of breath)등이 나타날 수 있다. 그러나, 비소세포성 폐암은 다른 암 보다 천천히 진행되기 때문에 초기에는 그 증상을 거의 보이지 않는다. 따라서, 비소세포성 폐암의 조기 발견 및 치료가 어려우며, 뼈, 간, 소장, 및 뇌 등 전신에 전이된 후에 발견할 가능성이 높다. 이에, 비소세포성 폐암의 진단 시 환자의 반수 이상이 수술을 할 수 없을 정도로 진행된 상태이므로 조기치료는 현실적으로 어렵다. 또한, 비소세포성 폐 암은 외과적 수술을 할 수 있을 만큼 진행되지 않은 경우라면 근치절제술과 같은 우선 수술을 시행하는데, 근치절제술을 시행할 수 있는 경우는 약 30 %에 불과한 실정이다. 나아가, 근치절제술을 시행한 전체환자들 대다수는 수술 절제 후에 보다 공격적인 질환으로 재발하여 사망하는 것으로 나타난다.Symptoms of such non-small cell lung cancer may include persistent cough, chest pain, weight loss, nail damage, joint pain, and shortness of breath. However, because non-small cell lung cancer progresses more slowly than other cancers, it rarely shows symptoms in the early stages. Therefore, early detection and treatment of non-small cell lung cancer is difficult, and it is highly likely to be detected after metastasis to the bones, liver, small intestine, and brain. Accordingly, at the time of diagnosis of non-small cell lung cancer, more than half of the patients are advanced enough to not be able to perform surgery, so early treatment is difficult in reality. In addition, if non-small cell lung cancer has not progressed enough to be surgically performed, a priority operation such as radical resection is performed, but only about 30% of cases in which radical resection can be performed. Furthermore, the majority of all patients who underwent radical resection appear to recur and die from a more aggressive disease after surgical resection.
이러한 이유로 비소세포성 폐암의 조기 치료를 위해, 새로운 치료법의 개발, 나아가 기존의 치료법에 대한, 치료 반응을 예측할 수 있는 새로운 방법에 대한 개발이 지속적으로 요구되고 있는 실정이다.For this reason, for the early treatment of non-small cell lung cancer, the development of a new treatment method, and furthermore, the development of a new method for predicting the treatment response to the existing treatment is continuously required.
발명의 배경이 되는 기술은 본 발명에 대한 이해를 보다 용이하게 하기 위해 작성되었다. 발명의 배경이 되는 기술에 기재된 사항들이 선행기술로 존재한다고 인정하는 것으로 이해되어서는 안 된다. The description underlying the invention has been prepared to facilitate understanding of the invention. It should not be construed as an admission that the matters described in the background technology of the invention exist as prior art.
한편, 아시인의 경우, 비소세포성 폐암 환자 중 약 50%에서 상피세포 성장인자 수용체(Epidermal Growth Factor Receptor, EGFR)의 돌연변이가 발견된다. EGFR은 HER 또는 erbB family라고도 불리는 티로신 키나아제 수용체 그룹의 일부로서, erbB family에는 EGFR (HER1/ErbB1), HER2 (ErbB2), HER3 (ErbB3) 그리고 HER4 (ErbB4)가 포함된다. 이러한, EGFR의 돌연변이는 EGFR의 티로신 키나아제 도메 인에 발생하여 EGFR 키나아제의 활성을 증가시킴에 따라, 세포 신호전달 체계를 지속적으로 활성화시켜 세포를 무제한으로 분화 및 성장하도록 한다.On the other hand, in the case of Asians, epidermal growth factor receptor (EGFR) mutations are found in about 50% of non-small cell lung cancer patients. EGFR is part of a group of tyrosine kinase receptors, also called HER or erbB family. The erbB family includes EGFR (HER1/ErbB1), HER2 (ErbB2), HER3 (ErbB3) and HER4 (ErbB4). These mutations in EGFR occur in the tyrosine kinase domain of EGFR and increase the activity of EGFR kinase, thereby continuously activating the cell signaling system to allow unrestricted differentiation and growth of cells.
이에, 이를 표적으로 하는 티로신 키나아제 억제제(tyrosine kinase inhibitors, TKIs)가 1차 요법으로 주로 사용되고 있으나, EGFR 돌연변이를 포함하는 비소세포성 폐암에 있어 TKIs를 통한 치료 요법은 9 내지 14개월 이내에 후천적 내성이 발생한다.Therefore, tyrosine kinase inhibitors (TKIs) that target this are mainly used as first-line therapy, but in non-small cell lung cancer containing EGFR mutations, the treatment therapy through TKIs is acquired resistance within 9 to 14 months. Occurs.
따라서, TKIs에 대한 한계를 극복하기 위하여, 2차 요법으로 PD-1 억제제(Programmed death receptor-1 inhibitors) 또는 PD-L1 억제제(programmed cell death ligand-1)가 사용될 수 있으나, PD-1 및 PD-L1 차단 치료 또한 EGFR 돌연변이 환자에 있어 낮은 민감성 및 생존율을 갖는 것으로 나타남에 따라, 이러한 한계를 극복할 수 있는 치료 전략이 필요한 실정이다.Therefore, to overcome the limitations for TKIs, PD-1 inhibitors (Programmed death receptor-1 inhibitors) or PD-L1 inhibitors (programmed cell death ligand-1) can be used as second-line therapy, but PD-1 and PD -L1 blocking treatment also appears to have low sensitivity and survival rate in patients with EGFR mutations, so there is a need for a treatment strategy that can overcome these limitations.
한편, PD-L1 차단의 치료 반응 예측에 있어서, 면역 조직 화학법 (immunohistochemistry, IHC)에 의한 종양 PD-L1 발현이 현재 PD-1 차단에 대한 최선의 예측 바이오 마커로 사용될 수 있다. 그러나, 종양 PD-L1 발현 의존적인 PD-L1의 치료 반응 예측의 정확도는 약물 효능을 확정할 정도로 높지 않다. 보다 구체적으로, PD-L1 발현 음성 환자가 PD-1 차단에 반응할 수 있고, PD-L1 발현 양성 환자가 PD-1 차단에 반응하지 않을 수 있다. 나아가, PD-L1이 없는 일부 반응 환자는 Checkmate 057 trial에서 PD-L1 양성인 경우 비슷한 반응 지속 기간을 보일 수 있다. 더욱이, PD-L1 발현은 동적이며, 시간적 및 공간적으로 변화할 수 있다. 이러한 PD-L1 발현의 변화 현상은 종양에 의해 발휘되는 적응 면역 저항성일 수 있다.Meanwhile, in predicting the therapeutic response of PD-L1 blockade, tumor PD-L1 expression by immunohistochemistry (IHC) can be currently used as the best predictive biomarker for PD-1 blockade. However, the accuracy of predicting the therapeutic response of PD-L1 dependent on tumor PD-L1 expression is not high enough to confirm drug efficacy. More specifically, PD-L1-expressing negative patients may respond to PD-1 blockade, and PD-L1-expressing positive patients may not respond to PD-1 blockade. Furthermore, some responders without PD-L1 may have a similar response duration if they were PD-L1 positive in the Checkmate 057 trial. Moreover, PD-L1 expression is dynamic and can change temporally and spatially. This change in PD-L1 expression may be adaptive immune resistance exerted by the tumor.
PD-L1 차단의 치료 반응 예측에 대한 바이오 마커로서, CD8 T세포 침윤, 염증 종양 표지, T세포 수용체 클론성 및 체성 돌연변이 부담 (somatic mutational burden) 이 이용될 수 있다. 그러나, 이상의 바이오 마커들은, 종양 조직을 얻는데 어려움을 갖고, 종양의 이질성 및 일부 바이오 마커의 유도 가능성을 가지고 있어, PD-1차단에 대한 치료 반응 예측에 있어 단일 마커로 이용되는 것에 어려움이 있을 수 있다.As biomarkers for predicting therapeutic response of PD-L1 blockade, CD8 T cell infiltration, inflammatory tumor markers, T cell receptor clonality and somatic mutational burden can be used. However, the above biomarkers have difficulties in obtaining tumor tissue, heterogeneity of tumors and the possibility of inducing some biomarkers, so it may be difficult to use them as single markers in predicting therapeutic response to PD-1 blockade. have.
한편, 본 발명의 발명자들은 EGFR 돌연변이를 포함하는 환자가 면역 항암 요법에 대한 반응성이 저하되어 있는 것을 인지하였으며, EGFR 돌연변이를 예시로 약물 반응성이 감소되어 있는 개체에서의 차이를 확인하여 이들의 약물 반응성에 대한 한계를 극복하고자 하였다. 이에, 본 발명의 발명자들은 이들이 가지고 있는 특정 면역 세포의 구성이 면역 항암 요법에 대한 반응성을 갖는 환자와 차별화되어 있다는 것을 발견하였으며, 이에 따라, 면역 항암 요법에 대한 반응성이 감소될 수 있다는 것을 발견할 수 있었다.On the other hand, the inventors of the present invention have recognized that the reactivity to immuno-cancer therapy is reduced in patients with EGFR mutations, and by identifying differences in individuals with reduced drug reactivity using EGFR mutations as an example, their drug reactivity to overcome the limitations of Accordingly, the inventors of the present invention have discovered that the composition of specific immune cells they have is differentiated from patients having responsiveness to immuno-cancer therapy, and accordingly, it can be found that the responsiveness to immuno-cancer therapy can be reduced. could
더욱이, 본 발명의 발명자들은 차별적으로 분포되어 있는 특정 면역 세포들이 종래의 분류에 의한 세포와 메커니즘이 상이하다는것을 발견하였다. 즉, 본 발명의 발명자들은 면역 항암 요법에 대한 반응성을 예측할 수 있는 특정 면역 세포를 특성화할 수 있는 유전자 지표(gene signature)를 발견하였다.Furthermore, the inventors of the present invention have found that specific immune cells that are differentially distributed have different mechanisms from cells by conventional sorting. That is, the inventors of the present invention have discovered a gene signature capable of characterizing a specific immune cell that can predict the responsiveness to immunotherapy.
그 결과, 본 발명의 발명자들은 면역 항암 요법, 즉, 면역 관문 억제제에 대한 치료 반응을 예측하기 위한 바이오 마커로서, GZMB+CD103+CD8+T세포를 통한, 새로운 치료 반응 예측 방법을 개발하기에 이르렀다.As a result, the inventors of the present invention have developed a novel therapeutic response prediction method using GZMB+CD103+CD8+T cells as a biomarker for predicting the therapeutic response to immune anticancer therapy, that is, an immune checkpoint inhibitor. .
이에, 본 발명이 해결하고자 하는 과제는, 개체에 대한 면역 항암 요법의 반응성일 조기에 예측하여, 치료 효과를 극대화시킬 수 있도록, GZMB+CD103+CD8+T세포의 수준을 측정하고, 이의 수준을 기초로 개체에 대한 면역 항암 요법의 치료 반응을 결정하여 제공할 수 있는, 치료 반응 예측 방법을 제공하는 것이다.Accordingly, the problem to be solved by the present invention is to measure the level of GZMB+CD103+CD8+T cells, and to measure the level of GZMB+CD103+CD8+T cells so as to maximize the therapeutic effect by predicting the responsiveness of the immunotherapy for the subject at an early stage. An object of the present invention is to provide a method for predicting a therapeutic response, which can be provided by determining the therapeutic response of an immuno-cancer therapy for an individual based on it.

보다 구체적으로, 도 2를 참조하면, TFH 세포는 CXCL13를 분비하여, B세포를 유도 즉, 세포의 여포 내로 침투시킬 수 있다. TFH 세포에 의하여 분비된 CXCL13는 B세포에서 발현된 CXCR5에 결합하여 B세포를 활성화시킬 수 있으며, 이에 따라, B세포는 이에 대한 항원을 분해한 뒤, 다양한 항원(HLA 및 MHC1)와 결합시킨 후, 세포의 포면에 표출시킬 수 있다. 그 다음, 이렇게 B세포의 표출된 항원이 세포 독성 효과를 갖는 TRM 세포 및 이의 아형 세포들의 TCR과 결합하여, TRM 세포 및 이의 아형세포들을 활성화시킬 수 있다. 나아가, B세포의 표출된 항원은 TRM 세포의 활성화뿐만 아니라, CXCL13을 분비할 수 있는 TFH 세포의 TCR과도 결합하여, TFH 세포를 활성화시켜 CXCL13의 분비를 더욱 촉진시킬 수 있다. 이에, 면역 항상성 및 독성 효과가 더욱 향상될 수 있다. 또한, 활성화된 TRM 세포 및 이의 아형세포들은 종양을 표적할 수 있는 종양 특이적 마커인 CD103을 포함함에 따라, 종양 이외의 다른 세포에는 반응하지 않고, 강한 세포 독성 분자인 GZMB를 분비하여 종양을 직접적으로 공격할 수 있다. 이러한, CXCR5+CD20+B세포, CD4+T세포, CXCL13+CD4+T세포, CD8+T세포, CD103+CD8+T세포 및 GZMB+CD103+CD8+T세포는, 종양 내에 침윤되어 면역 효과 즉, 면역 세포의 지속성 및 공격성을 향상시킬 수 있는 3 차 림프절 구조(tertiary lymphoid structures, TLS)를 형성할 수 있다. 이러한, TLS의 형성은, 면역 항암 요법 즉, 종양 미세 환경에 의하여 면역 세포의 세포 독성 효과를 억제시킬 수 있는 면역 관문 억제제에 대한 반응성을 향상시킬 수 있다.More specifically, referring to FIG. 2 , the T FH cells secrete CXCL13 to induce B cells, that is, to infiltrate into the follicles of the cells. CXCL13 secreted by T FH cells can activate B cells by binding to CXCR5 expressed in B cells. Then, it can be expressed on the surface of the cell. Then, the antigen expressed by the B cells may bind to the TCR of the T RM cells and subtypes thereof having a cytotoxic effect, thereby activating the T RM cells and the subtypes thereof.

이하에서는, 도 3a 내지 4b를 참조하여, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법에서 이용되는 GZMB+CD103+CD8+T세포에 대하여 구체적으로 설명한다.Hereinafter, with reference to FIGS. 3A to 4B , GZMB+CD103+CD8+T cells used in a method for predicting a therapeutic response to immuno-cancer therapy in lung cancer according to an embodiment of the present invention will be described in detail.
먼저, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법에서 이용되는 CD8 T세포의 아형에 대한 특성을 확인하기 위하여, DEGs(Differentially Expressed Genes) 분석을 수행되었다. 이에, 도 3a를 참조하면, CD8 T세포의 아형에 대한 DEGs 분석 결과 즉, mRNA 및 이의 단백질의 발현량을 도시한 도트 플롯(Dot plot)이 도시된다.First, in order to confirm the characteristics of the CD8 T cell subtype used in the method for predicting a therapeutic response to immunotherapy in lung cancer according to an embodiment of the present invention, differentially expressed genes (DEGs) analysis was performed. Accordingly, referring to FIG. 3A , a dot plot is shown showing the results of DEGs analysis for the CD8 T cell subtype, that is, the expression level of mRNA and its protein.
CD8 T세포의 아형인 C2는 가장 높은 수준으로 세포 독성(cytotoxicity)에 관여하는 유전자인 PRF1, GZMA, GZMB, GNLY 및 GZMH를 발현하고 있으며, 나아가, CD8 T세포의 분화(differentiation)에 관여하는 유전자인 ITGAE, ID2, IFNG, CD7 및 CXCR6 또한, C2 아형에서 가장 많이 발현되어 있는 것으로 나타난다. 이때, ITGAE는 조직 상주 기억 T세포 (tissue-resident memory CD8+T, TRM)에 대한 마커임에 따라, 이를 발현하는 C2 세포는 높은 세포 독성을 가지며, CD8 T세포로의 분화를 촉진시킬 수 있는 TRM 세포의 아형(TRM -like cells)일 수 있다. C2, a subtype of CD8 T cells, expresses PRF1, GZMA, GZMB, GNLY and GZMH, which are genes involved in cytotoxicity at the highest level, and furthermore, genes involved in the differentiation of CD8 T cells. ITGAE, ID2, IFNG, CD7 and CXCR6, which are also the most expressed in the C2 subtype. At this time, as ITGAE is a marker for tissue-resident memory T cells (tissue-resident memory CD8+T, T RM ), C2 cells expressing it have high cytotoxicity and can promote differentiation into CD8 T cells. It may be a subtype of T RM cells (T RM -like cells).
결국, CD8 T세포의 아형인 C2는 3a에 도시된 바와 같이, PRF1, GZMA, GZMB, GNLY, GZMH, ITGAE, ID2, IFNG, CD7, CXCR6, PDCD1, HAVCR2 및 LAG3을 차별적으로 발현할 수 있다. 이에, 도 3b를 참조하면, 전술한 CD8 T세포의 아형인 C2의 시그니처 유전자 마커에 대한 발현양 결과가 도시된다. 이때, 발현양은 CD8 T세포의 아형인 C0, C11 및 C14와의 비교를 통하여 도출되었으며, 이에 대한 발현양의 비율인 FC(fold change) 값을 나타내었다.Consequently, the CD8 T cell subtype, C2, can differentially express PRF1, GZMA, GZMB, GNLY, GZMH, ITGAE, ID2, IFNG, CD7, CXCR6, PDCD1, HAVCR2 and LAG3, as shown in Fig. 3a. Accordingly, referring to FIG. 3B , the expression level results for the signature gene marker of C2, a subtype of the aforementioned CD8 T cells, are shown. At this time, the expression level was derived through comparison with C0, C11 and C14, which are subtypes of CD8 T cells, and the FC (fold change) value, which is the ratio of the expression level, was shown.
보다 구체적으로, CD8 T세포의 아형인 C2는 GZMB가 1.2 이상, CD7이 0.9 이상, ID2가 0.5이상 및 ITGAE가 0.4 이상인 양(+)의 FC 값을 갖는 것으로 나타남에 따라, 이들이 3a에서와 마찬가지로 발현이 증가된(up-regulation) 유전자임을 의미할 수 있다. 나아가, CD8 T세포의 아형인 C2는 GZMK가 -1.4 미만인 음(-)의 FC 값을 갖는 것으로 나타남에 따라, GZMK가 3a에서와 마찬가지로 발현이 감소된(down-regulation) 유전자임을 의미할 수 있다.More specifically, C2, a subtype of CD8 T cells, was shown to have positive FC values with GZMB of 1.2 or more, CD7 of 0.9 or more, ID2 of 0.5 or more, and ITGAE of 0.4 or more, as in 3a. It may mean that the expression is increased (up-regulation) gene. Furthermore, as the CD8 T cell subtype, C2, was shown to have a negative FC value of less than -1.4 for GZMK, it may mean that GZMK is a down-regulation gene as in 3a. .
즉, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법에서 이용되는 CD8 T세포의 아형인 C2는 다른 CD8 T세포와 차별화된 유전자 발현 양상을 나타내며, 이에 따라 구별될 수 있다. 더욱이, CD8 T세포의 아형인 C2는 다른 CD8 T세포와 상이한 유전자 발현 양상을 나타남에 따라, 이에 따른 특성도 분명하게 구별될 수 있다.That is, C2, a subtype of CD8 T cells used in the method for predicting therapeutic response to immunotherapy in lung cancer according to an embodiment of the present invention, shows a gene expression pattern differentiated from other CD8 T cells, and thus can be distinguished have. Moreover, as the subtype of CD8 T cells, C2, exhibits different gene expression patterns from other CD8 T cells, the characteristics thereof can also be clearly distinguished.
결국, 이러한 차별적인 유전자 발현 양상 및 이에 따른 특성에 의하여 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법에서 이용되는 CD8 T세포의 아형인 C2는 개체에 대한 면역 항암 요법의 반응성에 영향을 미칠 수 있다. 이에, 도 3c를 참조하면, EGFR 돌연변이 유무에 따른 CD8 세포에 대한 UMAP 및 모자이크 플롯 결과가 도시된다. 이때, EGFR 돌연변이는 면역 항암 요법의 반응성이 낮은 대표적인 예시적 요인으로서, EGFR 돌연변이에 의하여 차별적인 요인을 분석할 경우, 낮은 면역 항암 요법 즉, 약물 반응성에 대한 원인을 유추할 수 있다. 이에, 면역 항암 요법의 반응성에 대한 예측 또는 치료 전략을 위하여, 예시적으로 EGFR 돌연변이의 유무를 비교하여, 이들의 차별적 구성을 도출하였다.After all, C2, a subtype of CD8 T cells used in the method for predicting a therapeutic response to immunotherapy in lung cancer according to an embodiment of the present invention, is based on the differential gene expression pattern and its characteristics. may affect the reactivity of Accordingly, referring to FIG. 3c , the results of UMAP and mosaic plots for CD8 cells with or without EGFR mutation are shown. In this case, the EGFR mutation is a representative exemplary factor with low reactivity of the immunotherapy, and when the differential factor is analyzed by the EGFR mutation, the cause of the low immunotherapy, that is, the drug reactivity can be inferred. Therefore, for the prediction or treatment strategy for the responsiveness of immunotherapy, by comparing the presence or absence of an exemplary EGFR mutation, their differential configuration was derived.
보다 구체적으로, EGFR 돌연변이 유무에 따라, 통계적으로 유의한 값을 나타내는 CD8 T세포의 아형은 C2인 것으로 나타나며, C2의 피어슨 잔차의 값은 -6.44인 것으로 나타난다. 즉, EGFR 돌연변이를 포함하는 경우, CD8 T세포의 아형인 C2 세포가 감소되어 있는 것으로 나타난다. 더욱이, 이러한 CD8 T세포의 아형인 C2 세포는 EGFR 돌연변이를 포함 개체에서 통계적으로 차별적인 발현은 타남에 따라, 면역 항암 요법의 반응성을 낮출수 있는 원인임을 의미할 수 있다.More specifically, depending on the presence or absence of EGFR mutation, the CD8 T cell subtype showing a statistically significant value is shown to be C2, and the Pearson residual value of C2 is shown to be -6.44. That is, when the EGFR mutation is included, it appears that C2 cells, a subtype of CD8 T cells, are reduced. Moreover, as the CD8 T-cell subtype, C2 cell, has a statistically differential expression in an individual containing an EGFR mutation, it may mean that it may be the cause of lowering the reactivity of immuno-cancer therapy.
결국, 도 3a 내지 3c의 결과에 따라, 낮은 면역 항암 요법의 반응성의 요인인 CD8 T세포의 아형인 C2는 ID2, IFNG, CD7, TNFRSF4, CCR7, IL7R, CXCR4, CXCR6, PRF1, GZMA, GNLY, GZMK, GZMH, GZMM, PDCD1, CTAL4, TIGIT, HAVCR2, LAG3, ICOS, TOX 및 TCF7 중 적어도 하나의 마커 유전자에 대한 mRNA 또는 이의 단백질을 발현할 수 있으며, 바람직하게, CD8 T세포의 아형인 C2는 PRF1, GZMA, GZMB, GNLY, GZMH, ITGAE, ID2, IFNG, CD7, CXCR6, PDCD1, HAVCR2 및 LAG3의 발현이 차별적으로 증가된 세포를 의미할 수 있다. 이에, CD8 T세포의 아형인 C2는 전술한 유전자 마커에 의하여, 분별될 수 있으며, 분별된 CD8 T세포의 아형인 C2를 통하여, 개체에 대한 면역 항암 요법의 반응성을 예측할 수 있다.In the end, according to the results of FIGS. 3a to 3c, C2, a subtype of CD8 T cells, which is a factor in the reactivity of low immune anticancer therapy, is ID2, IFNG, CD7, TNFRSF4, CCR7, IL7R, CXCR4, CXCR6, PRF1, GZMA, GNLY, mRNA for at least one marker gene of GZMK, GZMH, GZMM, PDCD1, CTAL4, TIGIT, HAVCR2, LAG3, ICOS, TOX and TCF7 or a protein thereof may be expressed.

Accordingly, C2, a subtype of CD8 T cells, can be discriminated by the above-described genetic marker, and the reactivity of immunotherapy to an individual can be predicted through the differentiated subtype of CD8 T cells, C2.
한편. TRM 세포는 순환하지 않고 말초 조직에 존재하는 활성화된 기억 T세포(effector memory T cells)의 하위 집단으로, 강한 세포독성에 관련된 분자인 PRF1(perforin), GZMB(granzyme B) 및 IFNG(IFN-gamma)을 발현 및 생산할 수 있다. 이에, 도 3d를 참조하면, CD8 T세포의 아형(TRM -like cells)에서 TRM 세포와 관련된 마커에 대한 발현 결과가 도시된다.Meanwhile. T RM cells are a subpopulation of activated memory T cells (effector memory T cells) that do not circulate and exist in peripheral tissues. gamma) can be expressed and produced. Accordingly, referring to FIG. 3D , the expression results for T RM cell-related markers in CD8 T cell subtypes (T RM -like cells) are shown.
세포 독성에 관련된 유전자인 PRF1, GZMA 및 GZMB은, CD8 T세포의 아형인 C2에서 가장 많이 발현되어 있는 것으로 나타나며, 면역에 대한 효과를 나타낼 수 있는 활성화(effector)에 관련된 유전자인 ID2 및 IFNG 또한, CD8 T세포의 아형인 C2에서 가장 많이 발현되어 있는 것으로 나타난다. 이에, CD8 T세포의 아형인 C2는 종양에서 세포 독성을 갖는 용해성 림프구(cytolytic lymphocyte)인 것을 의미할 수 있다. 나아가, 나이브(naive) 및 기억(memory)에 관련된 유전자인 CCR7 및 IL7R은 C14에서 가장 많이 발현되어 있음에 따라, C14는 나이브 T세포의 아형인 것을 의미할 수 있으며, C0 및 C11은 세포 독성에 관련된 유전자의 발현이 적으며, 활성화에 관련된 유전자가 발현되어 있음에 따라, 낮은 세포 독성을 갖는 활성화된 T세포의 아형임을 의미할 수 있다.PRF1, GZMA and GZMB, which are genes related to cytotoxicity, appear to be most expressed in C2, a subtype of CD8 T cells, and ID2 and IFNG, which are genes related to effectors that can exhibit effects on immunity, It appears to be most expressed in C2, a subtype of CD8 T cells. Accordingly, C2, a subtype of CD8 T cells, may mean cytolytic lymphocytes having cytotoxicity in tumors. Furthermore, since CCR7 and IL7R, which are genes related to naive and memory, are most expressed in C14, it may mean that C14 is a subtype of naive T cells, and C0 and C11 are related to cytotoxicity. The expression of the related gene is low, and the expression of the gene related to the activation may mean that it is a subtype of activated T cells with low cytotoxicity.
한편, 도 3e를 참조하면, CD8 T세포의 아형에서 TRM 세포에 특이적인 표면 마커인 ITGAE(CD103) 및 종양 특이적 반응에 관련된 마커인 ENTPD1에 대한 발현 결과가 도시된다. CD8 T세포의 아형인 C2는 TRM 세포에 특이적인 표면 마커인 ITGAE(CD103)와 종양 특이적 반응에 관련된 마커인 ENTPD1이 가장 많이 발현되어 있는 것으로 나타나며, 이에 따라, CD8 T세포의 아형인 C2는 무차별적 면역 반응 활성되는 방관자 T세포(bystander T cells)가 아닌, 종양 특이적 반응성을 나타내는 TRM 유사(아형, tumor-reactive TRM -like cells) 세포이다.Meanwhile, referring to FIG. 3E , expression results for ITGAE (CD103), a surface marker specific to T RM cells, and ENTPD1, a marker related to a tumor-specific response, are shown in the subtype of CD8 T cells. In C2, a subtype of CD8 T cells, ITGAE (CD103), a surface marker specific to T RM cells, and ENTPD1, a marker related to a tumor-specific response, are the most expressed. Accordingly, C2, a subtype of CD8 T cells are T RM -like (subtype, tumor-reactive T RM -like cells) cells that exhibit tumor-specific reactivity, not bystander T cells, which are activated in an indiscriminate immune response.
이에, EGFR 돌연변이를 포함하는 개체는 전술한 바와 같이 세포 독성을 가지는 C2의 아형이 감소되어 있음에 따라, 종양에 대한 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다. Accordingly, the individual containing the EGFR mutation has a reduced cytotoxic subtype of C2 as described above, and thus has a reduced toxicity to tumor, that is, an anticancer effect, and thus the therapeutic reactivity to immune anticancer therapy. can be reduced.
즉, ITGAE, ID2, IFNG, CD7, TNFRSF4, CCR7, IL7R, CXCR4, CXCR6, PRF1, GZMA, GZMB, GNLY, GZMK, GZMH, GZMM, PDCD1, CTAL4, TIGIT, HAVCR2, LAG3, ICOS, TOX 및 TCF7 중 적어도 하나, 바람직하게는, ITGAE, ID2, IFNG, CD7, CXCR6, PRF1, GZMA, GZMB, GNLY, GZMK, GZMH, GZMM, HAVCR2 및 LAG3의 마커 유전자에 대한 mRNA 또는 이의 단백질을 발현하는 CD8 T세포의 수가 정상 대조군 또는 EGFR 돌연변이를 포함하지 않는 개체보다 감소된 수준을 나타내는 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).i.e., among ITGAE, ID2, IFNG, CD7, TNFRSF4, CCR7, IL7R, CXCR4, CXCR6, PRF1, GZMA, GZMB, GNLY, GZMK, GZMH, GZMM, PDCD1, CTAL4, TIGIT, HAVCR2, LAG3, ICOS, TOX and TCF7 At least one, preferably, of a CD8 T cell expressing an mRNA for a marker gene of ITGAE, ID2, IFNG, CD7, CXCR6, PRF1, GZMA, GZMB, GNLY, GZMK, GZMH, GZMM, HAVCR2 and LAG3 or a protein thereof For individuals whose numbers show reduced levels than normal controls or individuals not containing the EGFR mutation, it can be determined that the therapeutic response to the immuno-cancer therapy is low (therapeutic response negative (-) individuals).
더욱이, ITGAE, ID2, IFNG, CD7, CXCR6, PRF1, GZMA, GZMB, GNLY, GZMK, GZMH, GZMM, HAVCR2 및 LAG3의 마커 유전자에 대한 mRNA 또는 이의 단백질의 수준이 정상 대조군 또는 EGFR 돌연변이를 포함하지 않는 개체보다 감소된 수준을 나타내는 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체). 특히, ITGAE 및/또는 GZMA의 마커 유전자에 대한 mRNA 또는 이의 단백질의 수준이 정상 대조군 또는 EGFR 돌연변이를 포함하지 않는 개체보다 감소된 수준을 나타내는 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다.Moreover, the level of mRNA or protein thereof for the marker genes of ITGAE, ID2, IFNG, CD7, CXCR6, PRF1, GZMA, GZMB, GNLY, GZMK, GZMH, GZMM, HAVCR2 and LAG3 is a normal control or does not contain an EGFR mutation. In the case of an individual exhibiting reduced levels than the individual, it may be determined that the therapeutic responsiveness to the immuno-cancer therapy is low (therapeutic response negative (-) individual). In particular, if the level of mRNA or protein thereof for a marker gene of ITGAE and/or GZMA is reduced compared to a normal control or an individual not containing an EGFR mutation, it is determined that the therapeutic response to the immuno-cancer therapy is low. can
나아가, 도 3f를 참조하면, CD8 T세포의 아형에서 EGFR 유전자 돌연변이 유무에 따른 세포 독성(cytotoxicity) 및 활성화(activation)에 관여하는 유전자에 대한 발현 결과가 도시된다. 세포 독성에 관여하는 유전자인 GZMB 및 활성화에 관여하는 유전자인 CD7, CD27 및 CXCR6 모두 EGFR 유전자 돌연변이를 포함하지 않는 개체(EGFR-WT)의 CD8 T세포의 아형인 C2에서 가장 많이 발현되는 것으로 나타난다. 이에, EGFR 돌연변이를 포함하는 개체는 종양을 직접적으로 공격하여 항암 효과를 발휘할 수 있는 TRM 유사 세포(TRM-like cells)인 C2의 활성 및 분포를 감소시킬 수 있으며, EGFR 돌연변이로 인하여 TRM 유사 세포(TRM-like cells)인 C2가 감소됨에 따라, 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다.Furthermore, referring to FIG. 3f , expression results for genes involved in cytotoxicity and activation according to the presence or absence of EGFR gene mutation in the CD8 T cell subtype are shown. GZMB, a gene involved in cytotoxicity, and CD7, CD27, and CXCR6, genes involved in activation, all appear to be most expressed in C2, a CD8 T cell subtype of an individual (EGFR-WT) that does not contain an EGFR gene mutation. Accordingly, an individual containing an EGFR mutation can reduce the activity and distribution of C2, which is a T RM -like cell capable of exerting an anticancer effect by directly attacking the tumor, and due to the EGFR mutation, the T RM As C2, which is a T RM -like cell, is reduced, therapeutic responsiveness to immuno-cancer therapy may be reduced.
더 나아가, 도 3g를 참조하면, EGFR 돌연변이 유무에 따른 종양 조직에서의 CD8+T세포, CD8+CD103+T세포 및 CD8+CD103+GZMB+T세포에 대한 면역조직화학법 결과가 도시된다. 먼저, 도 3g의 (a)를 참조하면, EGFR 돌연변이를 포함하지 않는 개체의 종양 조직에서 CD8+T세포, CD8+CD103+T세포 및 CD8+CD103+GZMB+T세포가 더 많은 면적을 차지하며, 더 많은 수를 가지고 분포되어 있는 것으로 나타난다. Furthermore, referring to FIG. 3G , immunohistochemistry results for CD8 + T cells, CD8 + CD103 + T cells, and CD8 + CD103 + GZMB + T cells in tumor tissues with or without EGFR mutation are shown. First, referring to (a) of FIG. 3G, CD8 + T cells, CD8 + CD103 + T cells, and CD8 + CD103 + GZMB + T cells occupy a larger area in the tumor tissue of an individual not containing the EGFR mutation. , appear to be distributed with a larger number.
이에, 단위 면적당 각 세포수를 계수한 결과인 도 3g의 (b)를 참조하면, EGFR-WT에 대한 종양 조직에서의 CD8+T세포의 개수는 약 200 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CD8+T세포의 개수는 약 120 no/mm2 이하인 것으로 나타난다.Accordingly, referring to FIG. 3g (b), which is the result of counting the number of cells per unit area, the number of CD8 + T cells in the tumor tissue for EGFR-WT is about 200 no/mm 2 appears to be abnormal, and the number of CD8 + T cells in the tumor tissue for EGFR-MT is about 120 no/mm 2 appears to be below.
또한, EGFR-WT에 대한 종양 조직에서의 CD8+CD103+T세포의 개수는 약 37 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CD8+ CD103+T세포의 개수는 약 5 no/mm2 이하인 것으로 나타난다.In addition, the number of CD8 + CD103 + T cells in the tumor tissue for EGFR-WT is about 37 no/mm 2 or more, and the number of CD8 + CD103 + T cells in the tumor tissue for EGFR-MT is about 5 no /mm 2 or less.
또한, EGFR-WT에 대한 종양 조직에서의 CD8+CD103+GZMB+T세포의 개수는 약 1.5 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CD8+ CD103+ GZMB+T세포의 개수는 약 1 no/mm2 이하인 것으로 나타난다.In addition, the number of CD8+CD103+GZMB+T cells in the tumor tissue for EGFR-WT was about 1.5 no/mm 2 It appears to be abnormal, and the number of CD8+ CD103+ GZMB+ T cells in the tumor tissue for EGFR-MT is about 1 no/mm 2 or less.
더 나아가, 보다 정확한 측정을 위하여 유세포 분석을 수행하였다. 이에, 도 3h를 참조하면, EGFR 돌연변이 유무에 따른 종양 조직에서의 CD8+T세포, CD8+CD103+T세포 및 CD8+CD103+GZMB+T세포에 대한 유세포 분석(Fluorescence-activated cell sorting, FACS) 결과가 도시된다. 이때, t-SNE를 이용하여 데이터의 차원을 줄여 시각화하였으며, 각 세포의 관측된 값은, 평균값과의 거리를 표현해주는 z-score로 표현되었다.Furthermore, flow cytometry was performed for more accurate measurement. Accordingly, referring to FIG. 3h , flow cytometry analysis of CD8 + T cells, CD8 + CD103 + T cells and CD8 + CD103 + GZMB + T cells in tumor tissues according to the presence or absence of EGFR mutation (Fluorescence-activated cell sorting, FACS) Results are shown. At this time, the dimension of the data was reduced and visualized using t-SNE, and the observed value of each cell was expressed as a z-score expressing the distance from the average value.
원안의 영역에서(area within the solid circle) EGFR 돌연변이를 포함하지 않는 개체(EGFR-WT)의 CD8, CD103 및 GZMB는 융합(merged) 이미지와 유사하게 높은 발현량을 갖는 것으로 나타난다. 즉, 전술한 세포 독성에 관여하는 마커를 발현하는 세포가 EGFR-WT에서는 고도로 농축되어 있으며, 이와 대조적으로, EGFR 돌연변이를 포함한 경우, 전술한 마커를 발현하는 세포가 결핍되어 있는 것으로 나타난다. 즉, EGFR 돌연변이로 인하여, 세포 독성을 갖는 세포가 감소될 수 있다.In the area within the solid circle, CD8, CD103 and GZMB of an individual not containing the EGFR mutation (EGFR-WT) appeared to have a high expression level similar to the merged image. That is, cells expressing the above-mentioned markers involved in cytotoxicity are highly enriched in EGFR-WT. In contrast, when the EGFR mutation is included, cells expressing the above-mentioned markers are deficient. That is, due to the EGFR mutation, cells with cytotoxicity can be reduced.
보다 구체적으로, 도 3i의 (a)를 참조하면, EGFR-WT의 경우, 전체 CD8+ T세포에 대하여 CD103을 발현하는 CD8+CD103+T세포의 비율은 약 57 %인 것으로 나타나며, EGFR-MT의 경우, 약 30 %인 것으로 나타나며, EGFR-MT에서 CD8+CD103+T세포가 유의하게 감소되어 있는 것으로 나타난다(p<0.05). 나아가, 도 7h의 (b)를 참조하면, 전술한 7h의 (a)에 대한 CD8+CD103+T세포 내에서 GZMB를 발현하는 CD8+CD103+GZMB+T세포의 비율은 EGFR-WT의 경우, 약 67 %인 것으로 나타나며, EGFR-MT의 경우, 약 30 %인 것으로 나타나며, EGFR-MT에서 CD8+CD103+ GZMB+T세포가 유의하게 감소되어 있는 것으로 나타난다(p<0.05).More specifically, referring to FIG. 3i (a), in the case of EGFR-WT, the ratio of CD8+CD103+ T cells expressing CD103 to the total CD8+ T cells is about 57%, and the EGFR-MT case, it appears to be about 30%, and CD8 + CD103 + T cells are significantly reduced in EGFR-MT (p<0.05). Furthermore, referring to (b) of Figure 7h, the ratio of CD8 + CD103 + GZMB + T cells expressing GZMB in CD8 + CD103 + T cells for the above-mentioned 7h (a) is EGFR-WT, It appears to be about 67%, and in the case of EGFR-MT, it appears to be about 30%, and CD8+CD103+GZMB+T cells are significantly reduced in EGFR-MT (p<0.05).
결국, EGFR 돌연변이와 같은 다양한 원인으로 인하여, CD8 T세포에서 세포 독성을 발휘할 수 있는 CD103 및 GZMB에 대한 발현이 억제되어 있는 경우, 이를 발현하는 CD8 T세포의 종양 내 분포 및 개수가 감소될 수 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다. After all, if the expression of CD103 and GZMB, which can exert cytotoxicity in CD8 T cells, is suppressed due to various causes such as EGFR mutation, the distribution and number of CD8 T cells expressing them in the tumor may be reduced. , and thus the therapeutic responsiveness to immuno-cancer therapy may be reduced.
따라서, EGFR 돌연변이를 포함하는 개체는 종양 특이적이며, 종양에 직접적으로 세포 독성 효과를 나타낼 수 있는 CD8+T세포 바람직하게는, CD8+CD103+T세포 및 CD8+CD103+GZMB+T세포를 포함하는, TRM 유사 세포인 CD8 T세포의 아형인 C2가 감소되어 있음에 따라, 종양에 대한 저항성 및 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다.Accordingly, an individual containing an EGFR mutation is tumor-specific and includes CD8 + T cells, preferably CD8 + CD103 + T cells and CD8 + CD103 + GZMB + T cells, which can exert a cytotoxic effect directly on the tumor. According to the decrease in C2, a subtype of CD8 T cells, which is a T RM -like cell, the resistance and toxicity to the tumor, that is, the anticancer effect, is reduced, and thus the therapeutic responsiveness to immunotherapy may be reduced. .
이에, 종양 조직 및 일반 조직에 대한 CD8+T세포의 수준이 120 no/mm2 이하인 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).Accordingly, the level of CD8 + T cells for tumor tissue and general tissue is 120 no/mm 2 In the case of the following subjects, it can be determined that the therapeutic response to the immuno-cancer therapy is low (therapeutic response negative (-) subjects).
또한, 종양 조직 및 일반 조직에 대한 CD8+CD103+T세포의 수준이 5 no/mm2 이하인 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).In addition, the level of CD8 + CD103 + T cells for tumor tissue and normal tissue was 5 no/mm 2 In the case of the following subjects, it can be determined that the therapeutic response to the immuno-cancer therapy is low (therapeutic response negative (-) subjects).
또한, 종양 조직 및 일반 조직에 대한 CD8+CD103+GZMB+T세포의 수준이 1 no/mm2 이하인 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).In addition, if the level of CD8 + CD103 + GZMB + T cells for tumor tissue and normal tissue is 1 no/mm 2 or less, it can be determined that the therapeutic response to immunotherapy is low (therapeutic response negative (-)). individual).
이상의 결과에 따라, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법은 PRF1, GZMA, GZMB, GNLY, GZMH, ITGAE, ID2, IFNG, CD7, CXCR6, PDCD1, HAVCR2 및 LAG3의 발현이 차별적으로 발현하는 CD8 T세포의 아형인 C2를 통하여, 개체에 대한 면역 항암 요법의 반응성을 정확하게 예측할 수 있다.According to the above results, the method for predicting treatment response to immunotherapy in lung cancer according to an embodiment of the present invention is PRF1, GZMA, GZMB, GNLY, GZMH, ITGAE, ID2, IFNG, CD7, CXCR6, PDCD1, HAVCR2 and LAG3 Through C2, a subtype of CD8 T cells that differentially express the expression of
이에, 이하에서는, 도 4a 및 4b를 참조하여, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법을 통한 항 PD-1 치료 반응 예측에 대하여 설명하도록 한다.Therefore, in the following, with reference to FIGS. 4A and 4B, prediction of anti-PD-1 treatment response through the method for predicting treatment response to immuno-cancer therapy in lung cancer according to an embodiment of the present invention will be described.
먼저, 면역 항암 요법은 종양의 면역 회피 및 억제의 기능을 저해하여, 세포 독성을 갖는 면역 세포의 활성을 향상시켜 항암 효과를 발휘함에 있다. 그러나, EGFR 돌연변이를 포함하는 개체의 경우, 이러한 세포 독성을 갖는 면역 세포의 개수가 감소되어 있음에 따라, 이의 효과를 향상시킬 수 있는 면역 억제제 즉, 면역 항암 요법의 치료 반응성이 낮을 수 있다. 그러나, EGFR 돌연변이를 포함하는 개체에서도 이러한 면역 세포가 향상되어 있을 경우, 면역 항암 요법에 대한 치료 반응이 긍정적일 수 있다.First, immunocancer therapy inhibits the function of immune evasion and suppression of tumors, thereby enhancing the activity of immune cells having cytotoxicity to exert anticancer effects. However, in the case of an individual containing an EGFR mutation, as the number of immune cells having such cytotoxicity is reduced, the therapeutic responsiveness of an immunosuppressive agent capable of enhancing its effect, that is, an immune anticancer therapy, may be low. However, if these immune cells are improved even in individuals with EGFR mutations, the therapeutic response to immunotherapy may be positive.
따라서, EGFR 돌연변이를 포함하는 개체에서 특이적인 빈도를 갖는 면역세포 즉, 본 발명의 일 실시예에 따른, 다양한 면역 세포의 아형의 수준에 따라, 면역 항암 요법에 대한 치료 반응이 예측될 수 있다.Therefore, according to the level of immune cells having a specific frequency in an individual containing an EGFR mutation, that is, various subtypes of immune cells according to an embodiment of the present invention, a therapeutic response to immune anticancer therapy can be predicted.
이에, 본 발명의 CD8 T세포의 아형인 C2(TRM-like cells)를 TCGA (The Cancer Genome Atlas)의 비소세포성폐암(lung adenocarcinoma, LUAD) 및 편평세포암(lung squamous cell carcinoma, LUSC)에서 EGFR 돌연변이 유무에 따라 검증한 결과인 도 4a를 참조하면, CD8 T세포의 아형인 C2(TRM-like cells)가 EGFR-MT에서 감소되어 있는 것으로 나타나며, 본 발명의 결과와 일치하는 것으로 나타난다. 즉, CD8 T세포의 아형인 C2(TRM-like cells)가 EGFR 돌연변이를 포함하는 폐암 및 이를 포함하지 않는 다양한 폐암에 있어, 공통적으로 모두 적용될 수 있는 적절한 평가 항목임을 의미할 수 있다. Accordingly, C2 (T RM -like cells), a subtype of CD8 T cells of the present invention, were treated with TCGA (The Cancer Genome Atlas) for lung adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC). Referring to FIG. 4a, which is the result of verification according to the presence or absence of EGFR mutations, it appears that C2 (T RM -like cells), a subtype of CD8 T cells, is reduced in EGFR-MT, which is consistent with the results of the present invention. . That is, it may mean that C2 (T RM -like cells), a subtype of CD8 T cells, is an appropriate evaluation item that can be commonly applied to lung cancer containing an EGFR mutation and various lung cancers not including the EGFR mutation.
따라서, 도 4b에서는 EGFR 돌연변이를 포함하는 특이적인 빈도를 갖는 면역세포 중 하나인 세포 독성을 나타내는 CD8 T세포의 아형인 C2(TRM-like cells)를 통하여 면역 항암 요법에 대한 치료 반응을 예측하도록 한다. Therefore, in FIG. 4b, it is possible to predict the therapeutic response to immune anticancer therapy through C2 (T RM -like cells), a subtype of CD8 T cells showing cytotoxicity, which is one of immune cells with a specific frequency including EGFR mutation. do.
도 4b를 참조하면, CD8 T세포의 아형인 C2(TRM-like cells)에 대한 면역 항암 요법 즉, 항 PD-1 반응에 대한 각각의 코호트에서의 검증 결과가 도시된다.Referring to FIG. 4B , the validation results in each cohort for immuno-cancer therapy, ie, anti-PD-1 response, are shown for C2 (T RM -like cells), a subtype of CD8 T cells.
먼저, 도 4b의 (a)를 참조하면, 종양 침윤성 CD8 T세포의 아형인 C2(TRM-like cells)과 항 PD-1 치료 반응 간의 양의 상관 관계를 갖는 것으로 나타난다. First, referring to (a) of FIG. 4B , it appears that there is a positive correlation between C2 (T RM -like cells), a subtype of tumor-infiltrating CD8 T cells, and the anti-PD-1 treatment response.
나아가, 도 4b의 (b)를 참조하면, 전술한 도 4b의 (a)에서 가장 높은 점수를 나타낸 환자에 대한 민감도 및 특이도에 대한 AUC 곡선이 도시된다. Furthermore, referring to FIG. 4B (b), an AUC curve for sensitivity and specificity for the patient showing the highest score in FIG. 4B (a) is shown.
YCC 코호트의 AUC는 0.854으로 높은 민감도 및 특이도를 가지는 것으로 나타남에 따라, 종양 침윤성 CD8 T세포의 아형인 C2(TRM-like cells)에 따른 항 PD-1 치료에 대한 반응 예측력이 우수함을 의미할 수 있다. 한편, YCC의 코호트에서는 18명의 환자 중 EGFR-MT 개체가 2명이였으며, 그 중 1명만이 반응자였다. 이에, CD8 T세포의 아형인 C2(TRM-like cells) 항 PD-1 치료에 대한 반응 예측력은 EGFR 돌연변이를 포함하는 개체뿐만 아니라 항 PD-1 치료 위한 다양한 폐암 개체에서도 적용될 수 있다. 즉, CD8 T세포의 아형인 C2(TRM-like cells)는 다양한 폐암 개체에서 항 PD-1 치료에 대한 치료 반응을 예측할 수 있는 바이오 마커로 이용될 수 있다.The AUC of the YCC cohort was 0.854, which was shown to have high sensitivity and specificity, indicating that the predictive power of response to anti-PD-1 treatment according to C2 (T RM -like cells), a subtype of tumor-infiltrating CD8 T cells, was excellent. can do. On the other hand, in the YCC cohort, there were 2 EGFR-MT subjects out of 18 patients, and only 1 of them was a responder. Accordingly, the predictive power of C2 (T RM -like cells), a subtype of CD8 T cells, to anti-PD-1 treatment can be applied not only to individuals with EGFR mutations but also to various lung cancer individuals for anti-PD-1 treatment. That is, C2 (T RM -like cells), a subtype of CD8 T cells, can be used as a biomarker that can predict the therapeutic response to anti-PD-1 treatment in various lung cancer individuals.
EGFR 돌연변이에 따른 면역 세포 분포 차이 확인Confirmation of differences in immune cell distribution according to EGFR mutation
이하에서는 도 5a 내지 5d를 참조하여, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법에 이용되는 다양한 면역 세포에 대하여 구체적으로 설명한다.Hereinafter, with reference to FIGS. 5A to 5D , various immune cells used in a method for predicting a therapeutic response to immuno-cancer therapy in lung cancer according to an embodiment of the present invention will be described in detail.
도 5a를 참조하면, EGFR 돌연변이 유무에 따른 면역 세포 확인 과정이 도시된다. 먼저, 면역 항암 요법에 대한 반응성을 예측하기 위하여, 면역 항암 요법에 대한 반응성을 낮출 수 있는 대표적인 원인인 EGFR 돌연변이를 예시적으로 선정하여 비교하였다. Referring to Figure 5a, the immune cell identification process according to the presence or absence of EGFR mutation is shown. First, in order to predict the responsiveness to immunotherapy, EGFR mutations, which are representative causes that can lower the responsiveness to immunotherapy, were selected and compared.
EGFR 돌연변이에 따른 특이적인 면역 세포 분포 차이 확인을 위하여, EGFR 돌연변이를 포함하지 않는 비소세포성 폐암 개체(EGFR-WT) 및 EGFR 돌연변이를 포함하는 비소세포성 폐암 개체(EGFR-MT)의 종양 조직(tumor tissue)을 외과적으로 절제하여 수집한 뒤, 백혈구 공통 항원인 CD45에 종양에 침윤된 백혈구(tumor-infiltrating CD45+leukocytes)를 선별(sorting)한 뒤, 10X Genomics 기술을 사용하여 단일 세포 RNA 시퀀싱(Single cell RNA sequencing, scRNA-seq)를 수행하였다.In order to identify specific differences in the distribution of immune cells according to EGFR mutations, tumor tissues of non-small cell lung cancer individuals (EGFR-WT) not containing EGFR mutations and non-small cell lung cancer individuals (EGFR-MT) containing EGFR mutations ( After the tumor tissue was surgically excised and collected, tumor-infiltrating CD45+leukocytes were sorted on CD45, a common antigen for white blood cells, and single-cell RNA sequencing was performed using 10X Genomics technology. (Single cell RNA sequencing, scRNA-seq) was performed.
이에, 도 5b를 참조하면, 전술한 과정에 의하여 도출된 EGFR 돌연변이 유무에 따른 면역 세포 결과가 도시된다. 이때, EGFR 돌연변이 유무에 따른 면역 세포 결과는 Seurat v.3.0 package16를 사용하여 전술한 과정에 의하 도출된 scRNA-seq 결과를 전처리한 뒤, UMAP를 통하여 차원을 축소시켜 시각화하였다. 나아가, 각각의 세포는 세포 내에 발현되어 있는 바이오마커(biomarker)따라 C0 내지 C17의 아형(subtype)으로 구별 및 분류되었다. 나아가, T세포의 경우, CD3D, CD3E, CD3G, 및 CD28 이며, CD4+T세포의 경우, CD4, CD8+세포의 경우, CD8A 및 CD8B, Treg 세포의 경우, FOXP3 및 IL2RA, NK 및 NKT세포의 경우, FCGR3A, FCGR3B, NCAM1, KLRB1, KLRC1, KLRD1, KLRF1, 및 KLRK1, 대식세포 및 단핵구의 경우, CD14, CD68, CD163, 및 C8F1R, B세포의 경우, CD19, MS4A1, CD79A, CD79B, 및 BLNK, 수지상 세포의 경우, IL3RA, CLEC4C, 및 NRP1, ILC2 세포의 경우, KIT 및 IL1RL1의 바이오 마커의 발현을 통하여, 면역 세포 및 이의 아형을 구별 및 분류하였다.Accordingly, referring to FIG. 5b , the results of immune cells according to the presence or absence of EGFR mutations derived by the above-described process are shown. At this time, the immune cell results according to the presence or absence of EGFR mutations were visualized by reducing the dimension through UMAP after preprocessing the scRNA-seq results derived by the above procedure using Seurat v.3.0 package16. Furthermore, each cell was distinguished and classified into subtypes C0 to C17 according to biomarkers expressed in the cells. Furthermore, in the case of T cells, CD3D, CD3E, CD3G, and CD28, in the case of CD4+ T cells, in the case of CD4, CD8+ cells, in CD8A and CD8B, in the case of Treg cells, FOXP3 and IL2RA, in the case of NK and NKT cells. , FCGR3A, FCGR3B, NCAM1, KLRB1, KLRC1, KLRD1, KLRF1, and KLRK1 for macrophages and monocytes, CD14, CD68, CD163, and C8F1R, for B cells, CD19, MS4A1, CD79A, CD79B, and BLNK, In the case of dendritic cells, IL3RA, CLEC4C, and in the case of NRP1 and ILC2 cells, immune cells and their subtypes were distinguished and classified through the expression of KIT and IL1RL1 biomarkers.
EGFR-MT 그룹과 EGFR-WT 그룹 간의 면역 세포가 차별적으로 분포되어 있는 것으로 나타나며, 각각의 면역 세포의 종류에 따른 아형의 구성의 분포 또한 상이한 것으로 나타난다. It appears that the immune cells are differentially distributed between the EGFR-MT group and the EGFR-WT group, and the distribution of the subtype composition according to the type of each immune cell is also different.
보다 구체적으로, Treg 세포는 C4, NK 세포는 C13, B 세포는 C8, 단핵구(monocytes) 및 대식세포(macrophage)는 C15, 수지상 세포(dendritic cells)는 C16, 및 IL-2 세포는 C17인 것으로 나타나며, 각각의 면역 세포의 개수는 EGFR 돌연변이 유무에 따라 차이가 있는 것으로 나타난다.More specifically, Treg cells are C4, NK cells are C13, B cells are C8, monocytes and macrophages are C15, dendritic cells are C16, and IL-2 cells are C17. It appears that the number of each immune cell is different depending on the presence or absence of EGFR mutation.
또한, CD8 T세포의 경우, C0, C2, C11 및 C14의 아형을 포함하고 있는 것으로 나타나며, CD4 T세포의 경우, C1, C3, C5, C6 및 C9의 아형을 포함하고 있는 것으로 나타나며, NKT세포의 경우, C7, C10 및 C12의 아형을 포함하고 있는 것으로 나타나며, 각각의 면역 세포에 대한 아형의 개수 및 비율은 EGFR 돌연변이 유무에 따라 차이가 있는 것으로 나타난다.In addition, in the case of CD8 T cells, it appears to contain the subtypes C0, C2, C11 and C14, and in the case of CD4 T cells, it appears to contain the subtypes of C1, C3, C5, C6 and C9, and NKT cells In the case of C7, C10 and C12, it appears that the subtypes are included, and the number and ratio of subtypes for each immune cell is different depending on the presence or absence of EGFR mutation.
한편, 도 5c를 참조하면, 전술한 C15의 대식세포 및 단핵구, C16의 수지상 세포 및 C17의 IL-2 세포는 대부분 6번 개체(P6)로부터 파생된 것으로 나타난다. 즉, C15, C16 및 C17의 면역 세포는 특정 환자로부터 파생된 편향 데이터임에 따라, 이를 제외하였다.Meanwhile, referring to FIG. 5C , the macrophages and monocytes of C15, dendritic cells of C16 and IL-2 cells of C17 are mostly derived from individual 6 (P6). That is, the immune cells of C15, C16 and C17 were excluded as they were biased data derived from a specific patient.
이에, 도 5d를 참조하면, 전술한 편향 데이터가 제외되어 도출된 모자이크 플롯(mosaic plot) 결과가 도시된다. 이때, 하기의 수학식 1의 피어슨 잔차(Pearson residual, rij)를 통하여, EGFR 돌연변이 유무에 따라, 각 면역 세포들의 비례 변화가 평가되었으며, r> 3.5 (augmentation) 및 r <-3.5 (depletion) 값의 임계치(threshold)를 갖는 집단에 대해서만 평가되었다 (|Pearson residual| > 2 for p-value < 0.05, |Pearson residual| > 4 for p-value < 0.01).Accordingly, referring to FIG. 5D , a mosaic plot result derived by excluding the aforementioned bias data is shown. At this time, through the Pearson residual (r ij ) of
수학식의 i는 각 면역세포의 인덱스(indices for each group), j는 아형(indices for cell subsets), O는 관찰된 세포 개수(observed cell counts) 및 E는 기대 세포 개수(expected cell counts)를 의미한다.In the equation, i is the index of each immune cell (indices for each group), j is the subtype (indices for cell subsets), O is the observed cell counts (observed cell counts), and E is the expected cell counts. it means.
또한, 모자이크 플롯의 면적은 세포의 빈도수에 비례적이며, 관찰된 세포 개수와 기대 세포 개수에 대한 편차에 대한 결과는 파랑, 빨강 및 회색으로 표시하였으며, 각각 파랑은 증가(augmentation), 빨강은 감소(고갈, depletion) 및 회색은 통계적 변화 없음(no significant change) 의미할 수 있다.In addition, the area of the mosaic plot is proportional to the cell frequency, and the results for the observed cell number and the expected cell number deviation are displayed in blue, red, and gray, respectively, with blue for augmentation and red for decreasing. (depletion) and gray can mean no significant change.
먼저, CD8 T세포의 경우, C2의 아형이 EGFR 돌연변이 유무에 따라 편향된 세포 수를 갖는 것으로 나타나며, EGFR 돌연변이 개체 집단에서 C2의 아형이 고갈되어 있는 것으로 나타난다.First, in the case of CD8 T cells, the subtype of C2 appears to have a biased cell number depending on the presence or absence of EGFR mutation, and it appears that the subtype of C2 is depleted in the EGFR mutant population.
그 다음, CD4 T세포의 경우, C1, C3 및 C9의 아형이 EGFR 돌연변이 유무에 따라 편향된 세포 수를 갖는 것으로 나타나며, EGFR 돌연변이 개체 집단에서 C1 및 C3의 아형이 증가되어 있으며, C9의 아형이 고갈되어 있는 것으로 나타난다.Next, in the case of CD4 T cells, the subtypes of C1, C3, and C9 were shown to have a biased cell number depending on the presence or absence of EGFR mutation, and the subtypes of C1 and C3 were increased in the EGFR mutant population, and the subtype of C9 was depleted. appears to have been
그 다음, Treg 세포(C4)은 EGFR 돌연변이 개체 집단에서 고갈되어 있는 것으로 나타난다.Then, Treg cells (C4) appear to be depleted in the EGFR mutant population.
그 다음, NKT세포의 경우, C7 및 C10의 아형이 EGFR 돌연변이 유무에 따라 편향된 세포 수를 갖는 것으로 나타나며, EGFR 돌연변이 개체 집단에서 C7 및 C10의 아형이 모두 증가되어 있는 것으로 나타난다.Then, in the case of NKT cells, the C7 and C10 subtypes were shown to have a biased cell number depending on the presence or absence of EGFR mutations, and both C7 and C10 subtypes were found to be increased in the EGFR mutant population.
마지막으로, B 세포(C8)은 EGFR 돌연변이 개체 집단에서 고갈되어 있는 것으로 나타난다.Finally, B cells (C8) appear to be depleted in the EGFR mutant population.
결국, EGFR 돌연변이를 포함하는 개체(EGFR-MT)는 돌연변이를 포함하지 않는 개체(EGFR-WT)와 상이한 면역 세포의 분포 및 비율을 가짐에 따라, 면역 항암 요법에 대한 반응성 및 이에 대한 효과가 상이할 수 있으며, 이를 통하여 면역 항암 요법에 대한 치료 반응을 예측할 수 있다. As a result, individuals with an EGFR mutation (EGFR-MT) have different distributions and ratios of immune cells from those without the mutation (EGFR-WT), so their responsiveness to and effects on immunotherapy are different. It is possible to predict the therapeutic response to immuno-cancer therapy through this.
나아가, EGFR-MT에서 감소되어 있거나 증가되어 있는 특정 면역 세포의 조절을 통하여, 면역 항암 요법에 대한 치료 반응을 향상시킬 수 있다.Furthermore, through the regulation of specific immune cells that are decreased or increased in EGFR-MT, it is possible to improve the therapeutic response to immune anticancer therapy.
EGFR 돌연변이에 따른 NKT 및 B세포의 아형에 대한 차이 확인Confirmation of differences in subtypes of NKT and B cells according to EGFR mutation
이하에서는 도 6a 내지 7을 참조하여, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법에 이용되는 NKT 및 B 세포에 대하여 구체적으로 설명한다.Hereinafter, with reference to FIGS. 6A to 7 , NKT and B cells used in a method for predicting a therapeutic response to immunotherapy in lung cancer according to an embodiment of the present invention will be described in detail.
먼저, 도 6a를 참조하면, EGFR 돌연변이 유무에 따른 NK 및 NKT세포에 대한 UMAP 및 모자이크 플롯 결과가 도시된다.First, referring to FIG. 6a , the results of UMAP and mosaic plots for NK and NKT cells according to the presence or absence of EGFR mutation are shown.
도 5d에서 전술한 바와 같이, 통계적으로 유의한 값을 나타내는 NKT세포의 아형은 C7 및 C10인 것으로 나타나며, 각각에 대한 피어슨 잔차의 값은 6.35 및 10.57인 것으로 나타난다. 즉, EGFR 돌연변이를 포함한 경우, NKT세포의 아형인 C7 및 C10 가 증가되어 있는 것으로 나타난다. As described above in FIG. 5D , the subtypes of NKT cells showing statistically significant values are C7 and C10, and the Pearson residual values for each are 6.35 and 10.57. That is, when the EGFR mutation is included, it appears that the subtypes of NKT cells, C7 and C10, are increased.
이때, NK 및 NKT세포의 아형에 대한 특성을 확인하기 위하여 DEGs(Differentially Expressed Genes) 분석을 수행하였다. 이에, 도 6b를 참조하면, EGFR 돌연변이 유무에 따른 NK 및 NKT세포의 아형에 대한 DEGs 분석 결과가 도시된다. At this time, DEGs (Differentially Expressed Genes) analysis was performed to confirm the characteristics of NK and NKT cell subtypes. Accordingly, referring to FIG. 6b , the results of DEGs analysis for NK and NKT cell subtypes according to the presence or absence of EGFR mutations are shown.
보다 구체적으로, 세포독성(cytotoxicity)에 관여하는 유전자인 PFR1 및 GZMB은 NKT세포의 C10 아형에서 발현이 감소되어 있는 것으로 나타나며, 세포활성(activation)에 관여하는 유전자인 TNFRSF18, IL2RB, CD7, CD44, TYROBP 및 TNFRSF1B은 NKT세포의 C7 및 C10 아형에서 발현이 모두 감소되어 있는 것으로 나타난다.More specifically, PFR1 and GZMB, which are genes involved in cytotoxicity, are shown to have decreased expression in the C10 subtype of NKT cells, and TNFRSF18, IL2RB, CD7, CD44, Both TYROBP and TNFRSF1B were expressed in the C7 and C10 subtypes of NKT cells.
즉, NKT세포의 아형인 C7는 세포활성이 감소(activation-L)되어 있는 세포이며, C7는 세포활성 및 세포독성이 감소(cytotoxicity-L, activation-L)되어 있는 세포이다.That is, C7, a subtype of NKT cells, is a cell with reduced cellular activity (activation-L), and C7 is a cell with reduced cytotoxicity and cytotoxicity (cytotoxicity-L, activation-L).
결국, EGFR 돌연변이를 포함하는 개체는 전술한 바와 같이 세포활성 및 세포독성이 감소되어 있는 아형을 다수 포함함에 따라, 종양에 대한 저항성 및 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응이 감소될 수 있다. After all, as the subject containing the EGFR mutation includes a number of subtypes with reduced cellular activity and cytotoxicity, as described above, resistance and toxicity to the tumor, that is, the anticancer effect, is reduced, and accordingly, the immune anticancer therapy treatment response may be reduced.
이에, PRF1, GZMB, TNFRSF18, IL2RB, CD7, CD44, TYROBP 및 TNFRSF1B 중 적어도 하나의 마커 유전자에 대한 mRNA 또는 이의 단백질을 발현하는 NKT세포의 수가 정상 대조군 또는 EGFR 돌연변이를 포함하지 않는 개체(EGFR-WT)보다 증가된 수준을 나타내는 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).Accordingly, the number of NKT cells expressing mRNA for at least one marker gene of PRF1, GZMB, TNFRSF18, IL2RB, CD7, CD44, TYROBP and TNFRSF1B or a protein thereof is a normal control or an individual that does not contain an EGFR mutation (EGFR-WT) ), it can be determined that the therapeutic responsiveness to immunotherapy is low (therapeutic response negative (-) subjects).
그 다음, 도 7을 참조하면, EGFR 돌연변이 유무에 따른 B세포에 대한 UMAP 및 모자이크 플롯 결과 및 주조직 적합 유전자 복합체(major histocompatibility complex, MHC)에 대한 발견 결과가 도시된다. 이때, B세포는 CD20 항원의 발현을 통하여 다른 면역 세포들과 구별될 수 있다.Then, referring to FIG. 7 , the results of the UMAP and mosaic plots for B cells and the findings of the major histocompatibility complex (MHC) are shown according to the presence or absence of EGFR mutations. At this time, B cells can be distinguished from other immune cells through the expression of the CD20 antigen.
B세포(C8)의 피어슨 잔차의 값은 -6.23인 것으로 나타난다. 즉, EGFR 돌연변이를 포함한 경우, 종양 침윤 B세포가 감소되어 있는 것으로 나타난다. The value of the Pearson residual of B cells (C8) appears to be -6.23. That is, when EGFR mutations are included, it appears that tumor-infiltrating B cells are reduced.
나아가, MHC에 대한 HLA-DPB1, HLA-DRB5, HLA-DQA2, HLA-C 및 TAP1의 유전자 발현은 EGFR 유전자를 포함하는 개체에서 모두 감소되어 있는 것으로 나타난다. 이때, MHC 발현이 결핍되거나 감소된 경우, 외부 항원에 대한 개체의 면역 반응이 약화될 수 있다. 이에, EGFR 돌연변이를 포함하는 개체는 전술한 바와 같이 B세포의 외부 항원 제시에 대한 MHC 발현이 감소되어 있음에 따라, B세포에 의한 T세포(CD4+T세포 및 CD8+T세포) 활성화가 감소될 수 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응이 감소될 수 있다. Furthermore, it appears that the gene expression of HLA-DPB1, HLA-DRB5, HLA-DQA2, HLA-C and TAP1 for MHC are all reduced in individuals including the EGFR gene. In this case, when MHC expression is deficient or reduced, the individual's immune response to the foreign antigen may be weakened. Accordingly, as described above, in the subject containing the EGFR mutation, as the MHC expression for the external antigen presentation of B cells is reduced, the activation of T cells (CD4 + T cells and CD8 + T cells) by B cells is reduced. and may reduce the therapeutic response to immune anticancer therapy.
즉, EGFR 돌연변이에 의하여 B세포의 항원 제시로 활성화된 T세포 수가 감소되어 있음에, 면역 관문 억제제를 통한 면역 항암 요법에 따른 T세포의 싸이토카인 분비 즉, 세포 독성 효과가 감소될 수 있다.That is, since the number of T cells activated by antigen presentation of B cells by EGFR mutation is reduced, cytokine secretion, ie, cytotoxic effect, of T cells according to immune anticancer therapy through an immune checkpoint inhibitor may be reduced.
결국, CD20+B세포의 수가 정상 대조군 또는 EGFR 돌연변이를 포함하지 개체(EGFR-WT)보다 감소된 수준을 나타내는 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).Ultimately, if the number of CD20 + B cells shows a reduced level than that of a normal control or a subject not containing an EGFR mutation (EGFR-WT), it can be determined that the therapeutic response to the immunotherapy is low (therapeutic response negative (-)). individual).
EGFR 돌연변이에 따른 CD4 및 Treg 세포의 아형에 대한 차이 확인Confirmation of differences in subtypes of CD4 and Treg cells according to EGFR mutation
이하에서는 도 8a 내지 8e를 참조하여, 본 발명의 일 실시예에 따른 폐암에서 면역 항암 요법에 대한 치료 반응 예측 방법에 이용되는 CD4 및 Treg 세포에 대하여 구체적으로 설명한다.Hereinafter, with reference to FIGS. 8A to 8E , CD4 and Treg cells used in a method for predicting a therapeutic response to an immuno-cancer therapy in lung cancer according to an embodiment of the present invention will be described in detail.
먼저, 도 8a를 참조하면, EGFR 돌연변이 유무에 따른 CD4 및 Treg 세포에 대한 UMAP 및 모자이크 플롯 결과가 도시된다.First, referring to FIG. 8a , the results of UMAP and mosaic plots for CD4 and Treg cells with or without EGFR mutation are shown.
*통계적으로 유의한 값을 나타내는 CD4 T세포의 아형은 C1, C3 및 C9인 것으로 나타나며, 각각에 대한 피어슨 잔차의 값은 8.48, 7.66 및 -7.37인 것으로 나타나며, Treg 세포(C4)의 피어슨 잔차의 값은 -7.07인 것으로 나타난다. 즉, EGFR 돌연변이를 포함한 경우, CD4 T세포의 아형인 C1 및 C3는 증가되어 있는 것으로 나타나며, CD4 T세포의 아형인 C9 및 Treg 세포는 감소되어 있는 것으로 나타난다.*The subtypes of CD4 T cells showing statistically significant values are shown to be C1, C3 and C9, and the Pearson residual values for each are 8.48, 7.66, and -7.37, respectively, and the Pearson residual of Treg cells (C4). The value appears to be -7.07. That is, when the EGFR mutation is included, CD4 T cell subtypes C1 and C3 are increased, and CD4 T cell subtypes C9 and Treg cells are decreased.
이때, CD4 T세포의 아형 및 Treg 세포에 대한 특성을 확인하기 위하여 DEGs(Differentially Expressed Genes) 분석을 수행하였다. 이에, 도 8b를 참조하면, EGFR 돌연변이 유무에 따른 CD4 T세포의 아형 및 Treg 세포에 대한 DEGs 분석 결과 즉, mRAN 및 이의 단백질의 발현량을 도시한 도트 플롯(Dot plot)이 도시된다. At this time, in order to confirm the characteristics of the CD4 T cell subtype and Treg cells, DEGs (Differentially Expressed Genes) analysis was performed. Accordingly, referring to FIG. 8b , a dot plot showing the expression levels of mRAN and its proteins is shown as a result of DEGs analysis for CD4 T cell subtypes and Treg cells according to the presence or absence of EGFR mutation.
보다 구체적으로, 면역 억제(immune suppression)에 관여하는 유전자인 CD52, ANXA1, ANXA2, 및 CXCR4은 C1 및 C3 아형에서 가장 많이 발현되어 있는 것으로 나타난다. 즉, 조력 T세포(helper T cell)인 CD4 T세포의 C1 및 C3는 면역을 억제하는 세포이다.More specifically, CD52, ANXA1, ANXA2, and CXCR4, which are genes involved in immune suppression, appear to be most expressed in the C1 and C3 subtypes. That is, C1 and C3 of CD4 T cells, which are helper T cells, are cells that suppress immunity.
결국, EGFR 돌연변이를 포함하는 개체는 전술한 바와 같이 면역반응을 억제하는 C1 및 C2의 아형을 다수 포함하고 있음에 따라, 종양에 대한 저항성 및 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다.After all, as the individual containing the EGFR mutation contains a number of subtypes of C1 and C2 that suppress the immune response as described above, the resistance and toxicity to the tumor, that is, the anticancer effect is reduced, and thus the immune anticancer effect Therapeutic responsiveness to therapy may be reduced.
이에, CD2, CD6, CD82. TMFRSF4, TNFRSF9, ICOS, CD27, CD28, TIGIT, PDCD1, CTLA4, CCR6, IL7R, SELL, CD52, ANXA1, ANXA2, CXCR4, FOXP3, IL3RA, IL2RB, IL3RG, IL10RA, MAGEH1, LAYN 및 GATA3 중 적어도 하나, 바람직하게는, CD52, ANXA1, ANXA2, 및 CXCR4의 마커 유전자에 대한 mRNA 또는 이의 단백질을 발현하는 CD4 T세포의 수가 정상 대조군 또는 EGFR 돌연변이를 포함하지 않는 개체보다 증가된 수준을 나타내는 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).Thus, CD2, CD6, CD82. At least one of TMFRSF4, TNFRSF9, ICOS, CD27, CD28, TIGIT, PDCD1, CTLA4, CCR6, IL7R, SELL, CD52, ANXA1, ANXA2, CXCR4, FOXP3, IL3RA, IL2RB, IL3RG, IL10RA, MAGEH1, LAYN and GATA3 Specifically, the number of CD4 T cells expressing mRNA for a marker gene of CD52, ANXA1, ANXA2, and CXCR4 or a protein thereof is higher than that of a normal control or an individual not containing the EGFR mutation. It can be determined that the treatment response to the therapy is low (therapeutic response negative (-) subjects).
한편, 세포활성(activation) 및 면역관문(immune checkpoint)에 관여하는 유전자인 CD2, CD6, CD82. TMFRSF4, TNFRSF9, ICOS, CD27, CD28, TIGIT, PDCD1 및 CTLA4은 CD4 T세포의 C9 아형에서 가장 많이 발현되어 있는 것으로 나타나며, 이러한 CD4 T세포의 C9 아형은 전술한 유전자 이외의 자가 항체 생성에 필수적인 여포 보조 T세포(Follicular helper T cells, TFH)의 마커인 CXCL13, ICOS, MAF, PDCD1, 및 SH2D1A 유전자와도 관련되어 있는 것으로 나타난다.On the other hand, CD2, CD6, CD82, which are genes involved in cell activation and immune checkpoint. TMFRSF4, TNFRSF9, ICOS, CD27, CD28, TIGIT, PDCD1 and CTLA4 appear to be most expressed in the C9 subtype of CD4 T cells. It also appears to be associated with CXCL13, ICOS, MAF, PDCD1, and SH2D1A genes, which are markers of Follicular helper T cells (T FH ).
여포 보조 T세포는 B세포의 발달 및 면역 활성 등의 다양한 기능을 조절하며, IL-4, IL-21, PD-1, CD69, OX40 및 CXCL13 등의 다양한 항원을 발현하고 있으며, 이 중 PD-1은 TFH 세포의 배아 중심(germinal centers)의 위치를 조절하고, TFH 세포의 기능을 보조하는 역할을 함에 따라, 여포 보조 T세포가 감소되어 있는 경우, 항 PD-1 치료의 효과가 경감될 수 있다.Follicle helper T cells regulate various functions such as B cell development and immune activity, and express various antigens such as IL-4, IL-21, PD-1, CD69, OX40 and CXCL13, among which PD- 1 regulates the location of the germinal centers of T FH cells and serves to support the functions of T FH cells. Therefore, when follicle helper T cells are reduced, the effect of anti-PD-1 treatment is reduced. can be
나아가, TFH 세포는 B세포에 대한 여포(follicles) 내로 침투(homing)를 유도하기 위하여, CXCL13을 생산한다. 즉, TFH 세포에서 분비하는 CXCL13에 의하여 3 차 림프절 구조(tertiary lymphoid structures, TLS)가 형성될 수 있다. 이때, TLS는 림프 노드가 아닌 곳에 T세포 및 B세포가 섬유성 그물망 세포(fibroblasts-like synovial cell, FRC)-유사 그물망 세포, HEV (high endothelial venules) 및 FDC (follicular dendritic cells)과 함께 구성된 면역 구조를 의미할 수 있다.Furthermore, T FH cells produce CXCL13 to induce homing into the follicles for B cells. That is, tertiary lymphoid structures (TLS) may be formed by CXCL13 secreted by T FH cells. At this time, TLS is not a lymph node, but T cells and B cells are fibroblasts-like synovial cells (FRC)-like reticular cells, HEV (high endothelial venules) and FDC (follicular dendritic cells) together with the immune system It can mean structure.
이에, 도 8c를 참조하면, Treg 세포 및 CD4 T세포에서의 아형에서의 TFH 세포와 관련된 마커에 대한 발현 결과 및 EGFR 돌연변이 유무에 따른 C9 아형의 CXCL13 발현 결과가 도시된다. Accordingly, referring to FIG. 8c , the expression results of T FH cell-related markers in the Treg cells and the CD4 T cell subtypes and the CXCL13 expression results of the C9 subtype according to the presence or absence of EGFR mutation are shown.
먼저, 도 8c의 (a)를 참조하면, TFH 세포의 마커 유전자인 CXCL13, PDCD1, MAF 및 SH2D1A의 발현은, CD4 T세포의 아형인 CD9에서 증가되어 있는 것으로 나타난다. First, referring to (a) of FIG. 8C , the expression of CXCL13, PDCD1, MAF and SH2D1A, which are marker genes of T FH cells, is increased in CD9, a subtype of CD4 T cells.
나아가, 도 8c의 (b)를 참조하면, CD4 T세포의 아형인 CD9에 대한 CXCL13의 발현은 EGFR 돌연변이를 포함하지 않는 개체(EGFR-WT)에서 더 많은 것으로 나타난다. 즉, EGFR 돌연변이를 포함하는 개체(EGFR-MT)에서 CXCL12의 발현이 감소되어 있는 것으로 나타남에 따라, EGFR 돌연변이는 CD4 T세포의 아형인 CD9에 대한 CXCL13의 발현을 감소시킬 수 있다.Furthermore, referring to (b) of FIG. 8C , the expression of CXCL13 for CD9, a subtype of CD4 T cells, is shown to be higher in subjects not containing the EGFR mutation (EGFR-WT). That is, as it was shown that the expression of CXCL12 is reduced in an individual containing an EGFR mutation (EGFR-MT), the EGFR mutation may reduce the expression of CXCL13 for CD9, a subtype of CD4 T cells.
한편, CD4 T세포의 아형인 CD9에서는 TFH 세포의 또 다른 특징 중 하나에 해당하는 CXCL13에 대한 수용체인 CXCR5과 TFH 세포 계통의 전사 인자(lineage-defining transcription factor)인 BCL6가 검출되지 않았다. 즉, CD4 T세포의 아형인 CD9은 일반적인 TFH 세포가 아닌 TFH 유사 세포(TFH-like cell)인 것을 의미할 수 있으며, 이는 TLS가 자주 발생하는 국부적인 염증 부위(local inflammatory sites)에서 주로 발견된다.On the other hand, in CD9, a subtype of CD4 T cells, CXCR5, a receptor for CXCL13, which is another characteristic of T FH cells, and BCL6, a lineage-defining transcription factor of the T FH cell lineage, were not detected. In other words, CD9, a subtype of CD4 T cells, may mean that they are T FH -like cells rather than general T FH cells, which are located in local inflammatory sites where TLS frequently occurs. mainly found
결국, TFH 세포의 주요 역할이 B세포의 유도임에 따라, EGFR 돌연변이를 포함하는 개체에서의 감소된 TFH 유사 세포의 수준은 비효율적인 TLS 형성을 초래하여, TLS 발달을 감소시키고, 이에 따라 종양에 대한 면역 세포의 면역 반응을 감소시킬 수 있다.Ultimately, as the main role of T FH cells is the induction of B cells, reduced levels of T FH -like cells in individuals with EGFR mutations result in inefficient TLS formation, resulting in reduced TLS development, thus It can reduce the immune response of immune cells to the tumor.
이에, 도 8d를 참조하면, EGFR 돌연변이 유무에 따른 종양 조직에서의 CD4+T세포 및 CXCL13+CD4+T세포에 대한 면역조직화학법 결과가 도시된다.Accordingly, referring to FIG. 8D , the results of immunohistochemistry for CD4 + T cells and CXCL13 + CD4 + T cells in tumor tissues with or without EGFR mutation are shown.
먼저, 도 8d의 (a)를 참조하면, EGFR 돌연변이를 포함하지 않는 개체(EGFR-WT)의 종양 조직에서 CD4+T세포 및 CXCL13+CD4+T세포가 더 많은 면적을 차지하는 것으로 나타난다. 이에, 단위 면적당 각 세포수를 계수한 결과인 도 8d의 (b)를 참조하면, EGFR-WT에 대한 종양 조직에서의 CD4+T세포의 개수는 약 1300 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CD4+T세포의 개수는 약 750 no/mm2 이하인 것으로 나타난다.First, referring to (a) of FIG. 8D , it appears that CD4 + T cells and CXCL13 + CD4 + T cells occupy a larger area in the tumor tissue of an individual (EGFR-WT) that does not contain an EGFR mutation. Accordingly, referring to FIG. 8d (b), which is the result of counting the number of cells per unit area, the number of CD4 + T cells in the tumor tissue for EGFR-WT is about 1300 no/mm 2 It appears to be abnormal, and the number of CD4 + T cells in the tumor tissue for EGFR-MT is about 750 no/mm 2 or less.
나아가, EGFR-WT에 대한 종양 조직에서의 CXCL13+CD4+T세포의 개수는 약 420 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CXCL13+CD4+T세포의 개수는 약 230 no/mm2 이하인 것으로 나타난다.Furthermore, the number of CXCL13 + CD4 + T cells in the tumor tissue for EGFR-WT is about 420 no/mm 2 or more, and the number of CXCL13 + CD4 + T cells in the tumor tissue for EGFR-MT is about 230 no/mm 2 or less.
결국, EGFR 돌연변이를 포함하는 개체는 전술한 바와 같이 B세포를 유도하고, 이에 따른 면역 반응 구조인 TLS를 형성할 수 있는 CXCL13을 생산하는 CD4 T세포인 C9 아형이 감소되어 있음에 따라, 종양에 대한 저항성 및 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다.As a result, as described above, the individual containing the EGFR mutation induces B cells as described above, and the CD4 T cell C9 subtype that produces CXCL13 capable of forming TLS, an immune response structure, is reduced. Resistance and toxicity, that is, the anticancer effect is reduced, and thus the therapeutic responsiveness to the immune anticancer therapy may be reduced.
이에, 종양 조직 및 일반 조직에 대한 CD4+T세포의 수준이 750 no/mm2 이하인 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).Accordingly, the level of CD4 + T cells for tumor tissue and general tissue is 750 no/mm 2 In the case of the following subjects, it can be determined that the therapeutic response to the immuno-cancer therapy is low (therapeutic response negative (-) subjects).
또한, 종양 조직 및 일반 조직에 대한 CXCL13+CD4+T세포의 수준이 230 no/mm2 이하인 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).In addition, if the level of CXCL13 + CD4 + T cells for tumor tissue and normal tissue is 230 no / mm 2 or less, it can be determined that the therapeutic response to immunotherapy is low (therapeutic response negative (-) individual) .
다시, 도 8a를 참조하면, 종양 침윤(tumor-infiltration)에 관여하는 유전자인 FOXP3, IL2RA, IL2RB, IL2RG, IL10RA, MAGEH1, LAYN, 및 GATA3은 C4에서 가장 많이 발현되어 있는 것으로 나타남에 따라, C4는 자가면역억제 및 면역 항상성을 유지하는 Treg 세포의 아형이다.Again, referring to FIG. 8A , genes involved in tumor-infiltration, FOXP3, IL2RA, IL2RB, IL2RG, IL10RA, MAGEH1, LAYN, and GATA3, are shown to be most expressed in C4, C4 is a subtype of Treg cells that maintain autoimmune suppression and immune homeostasis.
결국, EGFR 돌연변이를 포함하는 개체는 자가면역반응을 억제하고 면역 항상성을 유지시킬 수 있는 C4의 아형이 감소되어 있음에 따라, 종양에 대한 저항성 및 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성 및 지속성이 감소될 수 있다.As a result, the individual containing the EGFR mutation suppresses the autoimmune response and the C4 subtype that can maintain immune homeostasis is reduced, so the resistance and toxicity to the tumor, that is, the anticancer effect, is reduced, and thus the immunity Therapeutic responsiveness and persistence to anti-cancer therapy may be reduced.
이에, CD2, CD6, CD82. TMFRSF4, TNFRSF9, ICOS, CD27, CD28, TIGIT, PDCD1, CTLA4, CCR6, IL7R, SELL, CD52, ANXA1, ANXA2, CXCR4, FOXP3, IL3RA, IL2RB, IL3RG, IL10RA, MAGEH1, LAYN 및 GATA3 중 적어도 하나, 바람직하게는, FOXP3, IL2RA, IL2RB, IL2RG, IL10RA, MAGEH1, LAYN, 및 GATA3의 마커 유전자에 대한 mRNA 또는 이의 단백질을 발현하는 Treg 세포의 수가 정상 대조군 또는 EGFR 돌연변이를 포함하지 않는 개체보다 감소된 수준을 나타내는 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).Thus, CD2, CD6, CD82. At least one of TMFRSF4, TNFRSF9, ICOS, CD27, CD28, TIGIT, PDCD1, CTLA4, CCR6, IL7R, SELL, CD52, ANXA1, ANXA2, CXCR4, FOXP3, IL3RA, IL2RB, IL3RG, IL10RA, MAGEH1, LAYN and GATA3 Specifically, the number of Treg cells expressing mRNA for the marker genes of FOXP3, IL2RA, IL2RB, IL2RG, IL10RA, MAGEH1, LAYN, and GATA3 or a protein thereof is reduced compared to normal controls or individuals not containing the EGFR mutation. For individuals presenting, it can be determined that the therapeutic response to the immuno-cancer therapy is low (therapeutic response negative (-) individuals).
한편, Treg 세포는 전술한 FOXP3, IL2RA, IL2RB, IL2RG, IL10RA, MAGEH1, LAYN, 및 GATA3 유전자 마커 이외의 T세포 활성화에 관여하는 CD27, CD28, ICOS, and TNFRSF4 encoding OX40, TNFRSF9 encoding 41BB, 및 TNFRSF18 encoding GITR 마커 유전자 및 면역 관문 분자인 TIGIT 및 CTLA4 마커 유전자에서도 높은 발현 수준을 가질 수 있다. On the other hand, Treg cells are CD27, CD28, ICOS, and TNFRSF4 encoding OX40, TNFRSF9 encoding 41BB, and TNFRSF18 involved in T cell activation other than the aforementioned FOXP3, IL2RA, IL2RB, IL2RG, IL10RA, MAGEH1, LAYN, and GATA3 gene markers. The encoding GITR marker gene and immune checkpoint molecules TIGIT and CTLA4 marker genes may also have high expression levels.
나아가, 도 8e를 참조하면, EGFR 돌연변이 유무에 따른 Treg 세포의 아형인 C4에서 Treg 세포 활성 촉진 인자와 관련된 유전자 발현 결과가 도시된다. Treg 세포의 아형인 C4에서 TSC22D3 및 NR4A2의 발현은, EGFR-MT에서 증가되어 있는 것으로 나타난다. 이때, TSC22D3는 GILZ 및 NR4A2를 인코딩하는 유전자이며, 특히 GILZ는 수지상 세포 및 T세포에서 면역 억제 효과를 중재하는데, 종양 미세 환경과 같은 면역 억제성 환경에서의 GILZ의 과잉은 T세포의 암 항원에 대한 내성을 유발할 수 있다. Furthermore, referring to FIG. 8E , the results of gene expression related to the Treg cell activation promoting factor in C4, a subtype of Treg cells, are shown according to the presence or absence of EGFR mutations. Expression of TSC22D3 and NR4A2 in C4, a subtype of Treg cells, appears to be increased in EGFR-MT. At this time, TSC22D3 is a gene encoding GILZ and NR4A2, and in particular, GILZ mediates the immunosuppressive effect in dendritic cells and T cells. may lead to tolerance.
이에, EGFR 돌연변이를 포함하는 개체는 Treg 세포의 아형인 C4에 의하여 과잉 분비된 GILZ로 인하여, T세포의 항원에 대한 내성이 유도되어, 종양에 대한 저항성 및 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다.Accordingly, in the subject containing the EGFR mutation, due to GILZ excessively secreted by C4, a subtype of Treg cells, resistance to the antigen of T cells is induced, and resistance and toxicity to the tumor, that is, the anticancer effect is reduced, Accordingly, therapeutic responsiveness to immunotherapy may be reduced.
본 발명의 일 work of the invention 실시예에in the example 따른 폐암에서 면역 항암 Immunocancer in lung cancer following 요법에 대한 치료 반응treatment response to therapy 예측 방법에서 사용되는 면역 세포 검증 Immune Cell Validation Used in Predictive Methods
이하에서는, 도 9a 내지 10d를 참조하여, 본 발명의 일 실시예에 따른 EGFR 돌연변이를 포함하는 개체의 면역 항암 요법에서 사용되는 면역 세포에 대하여 항상성(homeostasis) 및 TLS를 통한 T세포의 활성화를 검증하도록 한다.Hereinafter, with reference to FIGS. 9a to 10d, the activation of T cells through homeostasis and TLS is verified for immune cells used in immune anticancer therapy of an individual containing an EGFR mutation according to an embodiment of the present invention. let it do
먼저, 면역 세포의 항상성에 대한 도 9a를 참조하면, EGFR 돌연변이를 포함하는 특이적인 빈도를 갖는 면역 세포인 CD8 T세포의 아형 간의 전환 확률에 대한 결과가 도시된다.First, referring to FIG. 9a for homeostasis of immune cells, the results for the conversion probability between subtypes of CD8 T cells, which are immune cells with specific frequencies containing EGFR mutations, are shown.
C2에서 C2로 다시 전환될 확률은, EGFR-WT인 경우, 0.57인 것으로 나타나며, EGFR-MT인 경우, 0.41인 것으로 나타나며, EGFR 돌연변이를 포함한 경우, C2에서 C2로 전환 확률이 더 낮은 것으로 나타난다. The probability of converting back to C2 from C2 is shown to be 0.57 in the case of EGFR-WT, and 0.41 in the case of EGFR-MT, and when EGFR mutation is included, the probability of conversion from C2 to C2 is lower.
이와는 대조적으로, C2에서 C0로 전환될 확률은, EGFR-WT인 경우, 0.39인 것으로 나타나며, EGFR-MT인 경우, 0.52인 것으로 나타나며, EGFR 돌연변이를 포함한 경우, C2에서 C0로 전환 확률이 더 높은 것으로 나타난다. In contrast, the probability of C2 to C0 conversion is shown to be 0.39 for EGFR-WT, 0.52 for EGFR-MT, and a higher probability of C2 to C0 conversion when including EGFR mutations appears to be
즉, EGFR 돌연변이는 강한 세포 독성을 나타내는 CD8 T세포에 대한 아형인 C2의 지속성(persistence)이 감소시키고, 낮은 세포 독성을 효과를 갖는 CD8 T세포에 대한 아형인 C0 세포로의 전환을 증가시키는 것으로 나타난다. 이에, EGFR 돌연변이를 포함한 경우, 종양 특이적으로 강한 세포 독성을 갖는 TRM 유사 세포(C2, TRM-like cells)의 항상성이 감소되어, 면역 항암 요법에 대한 항암 효과의 효과 즉, 항암 유지 지속 기간이 감소될 수 있다.That is, the EGFR mutation decreases the persistence of C2, a subtype for CD8 T cells, which exhibits strong cytotoxicity, and increases conversion to C0 cells, which is a subtype for CD8 T cells with low cytotoxicity. appear. Accordingly, when the EGFR mutation is included, the homeostasis of T RM-like cells (C2, T RM - like cells) having a tumor-specific strong cytotoxicity is reduced, so that the effect of the anti-cancer effect on the immune anti-cancer therapy, that is, the maintenance of anti-cancer is maintained. The period may be reduced.
결국, 종양 조직 및 일반 조직에 대한 CD8 T세포에 대한 아형인 C2(TRM 유사 세포, GZMB+CD103+CD8+T세포)에서 C2 세포로의 전환 확률이 41 % 이하인 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).After all, in the case of individuals with a conversion probability of 41% or less from C2 (T RM -like cells, GZMB+CD103+CD8+T cells), which is a subtype of CD8 T cells to tumor tissue and normal tissue, to C2 cells, immuno-cancer therapy can be determined to be low in response to treatment (negative (-) subjects responding to treatment).
나아가, 종양 조직 및 일반 조직에 대한 CD8 T세포에 대한 아형인 C2(TRM 유사 세포, GZMB+CD103+CD8+T세포)에서 C0 세포로의 전환 확률이 52 % 이상인 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(+) 개체).Furthermore, in the case of an individual with a conversion probability of 52% or more from C2 (T RM -like cells, GZMB+CD103+CD8+T cells), which is a subtype of CD8 T cells to tumor tissues and normal tissues, to C0 cells, immunotherapy may be determined to be low in response to treatment (negative (+) subjects responding to treatment).
그 다음, 면역 세포의 전사 조절에 대한 도 9b를 참조하면, CD8 T세포에 대한 아형인 C2(TRM 유사 세포, TRM-like cells)에서 차등적으로 발현되어 있는 전사 인자에 대한 DEGs 결과가 도시된다. 이때, 상향조절(upregulated)되어 있는 전사 인자(transcription factors, TFs)는 점선 테두리로 표시되었다.Next, referring to FIG. 9b for the transcriptional regulation of immune cells, the DEGs results for the transcription factors differentially expressed in C2 (T RM -like cells, T RM -like cells), which are subtypes for CD8 T cells, are is shown At this time, the upregulated (upregulated) transcription factors (transcription factors, TFs) are indicated by a dotted border.
CD8 T세포에 대한 아형인 C2(TRM 유사 세포)에서 상향 조절되어 있는 전사 인자는, SERTAD1, IRF1, ARID5B, ELF1, SLAZ, BHLHE40, FOSL2, RBPJ, ID2 및 HOPX인 것으로 나타나며, 이 중, ID2, RBPJ 및 BHLHE40은 TRM 세포의 발달 및 항상성에 관여하는 할 수 있다. 특히, RBPJ는 노치(NOTCH)와 관련되어 TRM 세포를 분화, 유지 및 활성화하는데 필요한 전사 활성화체(transcriptional activator)를 형성함에 관련되어 있다.Transcription factors up-regulated in C2 (T RM -like cells), a subtype for CD8 T cells, are SERTAD1, IRF1, ARID5B, ELF1, SLAZ, BHLHE40, FOSL2, RBPJ, ID2 and HOPX. Among them, ID2 , RBPJ and BHLHE40 may be involved in the development and homeostasis of T RM cells. In particular, RBPJ is involved in the formation of a transcriptional activator required for differentiation, maintenance and activation of T RM cells in association with Notch.
이에, 도 9c를 참조하면, EGFR 돌연변이 유무에 따른, TRM 세포를 분화, 유지 및 활성화에 관여하는 RBPJ 및 NOTCH1 유전자에 대한 발현 결과가 도시된다. 이때, 발현 결과는 스피어만 상관 계수(Spearman's rank correlation)를 통하여 표현되었으며, 상관 계수가 커질수록 두 유전자가 연관되어 있음을 의미할 수 있다.Accordingly, referring to FIG. 9c , the expression results for the RBPJ and NOTCH1 genes involved in T RM cell differentiation, maintenance and activation are shown according to the presence or absence of EGFR mutation. In this case, the expression result was expressed through Spearman's rank correlation, and as the correlation coefficient increases, it may mean that the two genes are related.
EGFR-WT의 경우, CD8 T세포에 대한 아형인 C2(TRM 유사 세포)에서 RBPJ 및 NOTCH1 모두 TRM 세포의 분화 및 유지에 관련된 다양한 유전자와 높은 양(+)의 상관 관계를 갖는 것으로 나타난다. In the case of EGFR-WT, both RBPJ and NOTCH1 in C2 (T RM -like cells), a subtype for CD8 T cells, have a high positive (+) correlation with various genes involved in the differentiation and maintenance of T RM cells.
이와는 대조적으로, EGFR-MT의 경우, CD8 T세포에 대한 아형인 C2(TRM 유사 세포)에서 RBPJ 및 NOTCH1 모두 TRM 세포의 분화 및 유지에 관련된 다양한 유전자와 낮은 음(-)의 상관 관계를 갖는 것으로 나타난다. In contrast, in the case of EGFR-MT, both RBPJ and NOTCH1 in C2 (T RM -like cells), a subtype for CD8 T cells, showed a low negative correlation with various genes involved in the differentiation and maintenance of T RM cells. appears to have
보다 구체적으로, 전술한 도 9c의 발현 결과를 산점도(scatter plots) 및 회귀 곡선(regression curver)으로 나타낸, 도 9d를 참조하면, EGFR-MT의 경우, EGFR-WT보다 유전자 간의 상관 관계에 대한 계수가 0에 가깝거나 음의 상관 계수를 가짐에 따라, 관계가 소실되거나, 역 상관 관계를 갖는 것으로 나타난다.More specifically, referring to FIG. 9d , which shows the expression result of FIG. 9c described above as scatter plots and a regression curver, in the case of EGFR-MT, the coefficient of correlation between genes rather than EGFR-WT As is close to zero or has a negative correlation coefficient, the relationship disappears or appears to have an inverse correlation.
결국, EGFR 돌연변이는 RBPJ 및 NOTCH1에 의한 TRM 세포 및 TRM 유사 세포의 분화, 유지 및 항상성을 감소시킬 수 있으며, TRM 세포 및 TRM 유사 세포는 RBPJ 및 NOTCH1 네트워크에 의하여 분화, 유지 및 항상성이 조절됨을 의미할 수 있다.Ultimately, EGFR mutations can reduce the differentiation, maintenance and homeostasis of T RM cells and T RM-like cells by RBPJ and NOTCH1, and T RM cells and T RM -like cells differentiate, maintain and homeostasis by RBPJ and NOTCH1 networks. This may mean that it is regulated.
그 다음, TLS를 통한 T세포의 활성화에 대한 도 10a를 참조하면, EGFR 돌연변이 유무에 따른 세포 및 세포간의 상호 작용(cell-cell interaction) 즉, 리간드(ligand) 및 수용체(receptor)에 대한 DEGs 분석 결과 즉, mRAN 및 이의 단백질의 발현량을 도시한 도트 플롯(Dot plot)이 도시된다. 이때, 결과값은 유전자 쌍의 평균 발현 값을 의미할 수 있다.Then, referring to FIG. 10a for the activation of T cells through TLS, cell-cell interaction with or without EGFR mutation, that is, DEGs analysis for ligands and receptors A result, that is, a dot plot showing the expression level of mRNA and its protein is shown. In this case, the result value may mean an average expression value of a gene pair.
EGFR-MT의 경우, CXCL13-CXCR5 축(axis)을 통한 TRM 세포 및 B세포의 상호 작용이 약한 것으로 나타난다. 즉, 각 세포에서 발현되는 리간드 및 수용체에 대한 발현이 낮으며, 이에 따라, 리간드 및 수용체의 결합 및 상호작용으로 발생하는 면역 효과가 감소될 수 있다.In the case of EGFR-MT, the interaction between T RM cells and B cells via the CXCL13-CXCR5 axis appears to be weak. That is, the expression of the ligand and the receptor expressed in each cell is low, and thus, the immune effect generated by the binding and interaction of the ligand and the receptor may be reduced.
이에, 도 10b를 참조하면, CXCL13-CXCR5를 통한 면역 상호 작용을 검증하기 위하여, EGFR 돌연변이 유무에 따른 T세포 및 B세포의 리간드 및 수용체의 결합을 통하여 발생된 TLS 구조에 대한 면역조직화학법 결과가 도시된다. Accordingly, referring to FIG. 10b, in order to verify the immune interaction through CXCL13-CXCR5, immunohistochemistry results for the TLS structure generated through the binding of ligands and receptors of T cells and B cells according to the presence or absence of EGFR mutations is shown
먼저, 도 10b의 (a)를 참조하면, EGFR 돌연변이를 포함하지 않는 개체(EGFR-WT)의 종양 조직에서 CD4+T세포, CD8+T세포 및 B세포에 의하여 형성된 TLS가 더 많은 면적을 차지하는 것으로 나타난다. 이에, 면적을 측정하여, 수치적으로 비교한 결과인 도 10b의 (b)를 참조하면, EGFR-WT에 대한 종양 조직에서의 TLS의 면적은 약 17 mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 TLS의 면적은 약 5 mm2 이하인 것으로 나타난다. 즉, EGFR 돌연변이는 면역 세포의 상호 작용인 TLS 형성을 EGFR-WT에 비하여 약 70 % 감소시킬 수 있다.First, referring to FIG. 10b (a), in the tumor tissue of an individual (EGFR-WT) not containing the EGFR mutation, TLS formed by CD4 + T cells, CD8 + T cells and B cells occupies a larger area. appears to be Accordingly, referring to FIG. 10b (b), which is a numerical comparison result by measuring the area, the area of TLS in the tumor tissue for EGFR-WT is about 17 mm 2 appears to be abnormal, and the area of TLS in the tumor tissue for EGFR-MT is about 5 mm 2 appears to be below. That is, the EGFR mutation can reduce TLS formation, an immune cell interaction, by about 70% compared to EGFR-WT.
나아가, 10c를 참조하면, 전술한 9b의 TLS 영역에서 EGFR 돌연변이 유무에 따른 면역 세포에 대한 면역조직화학법 결과가 도시된다.Furthermore, referring to 10c, immunohistochemistry results for immune cells according to the presence or absence of EGFR mutations in the TLS region of 9b are shown.
CD4, CD20, CD8, CXCL13, CXCR5 및 CD103을 발현하는 세포의 빈도 및 개수는 EGFR-WT의 TLS에서 더 많은 것으로 나타난다. 보다 구체적으로, 도 9c에 대한 결과를 단위 면적당 각 세포수를 계수한 결과인 도 10d를 참조하면, EGFR-WT에 대한 종양 조직에서의 CD4+T세포의 개수는 약 27000 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CD4+T세포의 개수는 약 600 no/mm2 이하인 것으로 나타난다.The frequency and number of cells expressing CD4, CD20, CD8, CXCL13, CXCR5 and CD103 appear to be higher in TLS of EGFR-WT. More specifically, referring to FIG. 10d , which is the result of counting the number of cells per unit area, the number of CD4 + T cells in the tumor tissue for EGFR-WT is about 27000 no/mm 2 appears to be abnormal, and the number of CD4 + T cells in the tumor tissue for EGFR-MT is about 600 no/mm 2 appears to be below.
또한, EGFR-WT에 대한 종양 조직에서의 CXCL13+CD4+T세포의 개수는 약 10000 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CXCL13+CD4+T세포의 개수는 약 1500 no/mm2 이하인 것으로 나타난다.In addition, the number of CXCL13 + CD4 + T cells in the tumor tissue for EGFR-WT is about 10000 no/mm 2 or more, and the number of CXCL13 + CD4 + T cells in the tumor tissue for EGFR-MT is about 1500 no/mm 2 or less.
또한, EGFR-WT에 대한 종양 조직에서의 CD8+T세포의 개수는 약 7500 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CD8+ CD4+T세포의 개수는 약 1000 no/mm2 이하인 것으로 나타난다.In addition, the number of CD8 + T cells in the tumor tissue for EGFR-WT was about 7500 no/mm 2 appears to be abnormal, and the number of CD8+ CD4+ T cells in the tumor tissue for EGFR-MT is about 1000 no/mm 2 or less.
또한, EGFR-WT에 대한 종양 조직에서의 CD103+CD8+T세포의 개수는 약 2900 no/mm2 이상인 것으로 나타나며, EGFR-MT에 대한 종양 조직에서의 CD103+CD8+ CD4+T세포의 개수는 약 500 no/mm2 이하인 것으로 나타난다.In addition, the number of CD103 + CD8 + T cells in the tumor tissue for EGFR-WT is about 2900 no/mm 2 or more, and the number of CD103 + CD8 + CD4 + T cells in the tumor tissue for EGFR-MT is about It appears to be less than 500 no/mm 2 .
결국, EGFR 돌연변이를 포함하는 개체는 TLS를 형성할 수 있는 B세포, CD4+T세포 및 CD8+T세포 바람직하게는, 및 B세포, B세포와 상호 작용을 야기할 수 있는 리간드인 CXCL12을 발현하는 CD4+T세포(CXCL13+CD4+T세포), 종양 특이적으로 강한 세포 독성을 나타낼 수 있는 CD103+CD8+T세포 및 GZMB+CD103+CD8+T세포가 감소되어 있음에 따라, 종양에 대한 저항성 및 독성 즉, 항암 효과가 감소되어 있으며, 이에 따른 면역 항암 요법에 대한 치료 반응성이 감소될 수 있다.Consequently, an individual containing an EGFR mutation expresses CXCL12, a ligand capable of causing interaction with B cells, CD4 + T cells and CD8 + T cells, preferably, and B cells, capable of forming TLS. CD4+ T cells (CXCL13+CD4+ T cells), CD103+CD8+ T cells and GZMB+CD103+CD8+ T cells that can exhibit strong tumor-specific cytotoxicity are decreased. Resistance and toxicity, that is, the anti-cancer effect is reduced, and thus the therapeutic responsiveness to the immune anti-cancer therapy may be reduced.
이에, 종양 조직 및 일반 조직에 대한 TLS의 면적이 5mm2 이하이거나, 정상 대조의 조직에 대한 TLS 면적의 수준보다 70 %이상 감소된 수준을 나타내는 개체의 경우, 면역 항암 요법에 대한 치료 반응성이 낮은 것으로 결정할 수 있다(치료 반응 음성(-) 개체).Therefore, the area of TLS for tumor tissue and general tissue is 5 mm 2 or less, or for an individual exhibiting a level that is reduced by 70% or more than the level of TLS area for tissue of a normal control, the therapeutic response to immunotherapy is low. (negative (-) subjects responding to treatment).
이상의 결과에 따라, EGFR 돌연변이와 같은 원인에 의하여 면역 항암 요법에 대한 반응성이 낮은 개체의 경우, CD8 T세포의 아형인 C2뿐만 아니라, CXCR5+CD20+B세포 또는 CXCL13+CD4+T세포를 포함하는 다양한 면역 세포들의 수준이 차별적으로 분포되어 있음에 따라, 이를 통하여 면역 항암 요법에 대한 반응성을 예측할 수 있다.According to the above results, in the case of individuals with low reactivity to immunotherapy due to causes such as EGFR mutation, not only C2, which is a subtype of CD8 T cells, but also CXCR5 + CD20 + B cells or CXCL13 + CD4 + T cells. As the levels of various immune cells are differentially distributed, it is possible to predict the responsiveness to immuno-cancer therapy through this.
