Abstract
Description
例えば、非特許文献1及び2においては、特定疾病抗原のエピトープ等の9merペプチドを末梢血単核球に加えることにより、そこからCTLの誘導を試みている。また、非特許文献3及び4では、末梢血単核球よりDCを得、そこに抗原ペプチドを添加させることで抗原提示機能を付与し、そのDCとともに末梢血リンパ球より分離したCD8陽性T細胞を培養することで、該疾病抗原特異的なCTLを誘導している。
更に、非特許文献5では、造血前駆細胞より得たDCと抗原ペプチドによるDCワクチンを行い、次いで単球由来のDCに抗原を加えたものと末梢血単核球より分離したCD8陽性T細胞とを共培養することにより抗原特異的なCTLを誘導している。
このように、免疫細胞療法においては、より効果の高い細胞を培養・利用することが非常に重要であり、現在も多種多様な手法・技術の開発が行われている。
<第一の実施形態:本発明の疾病抗原特異的CTLとγδT細胞の同時誘導方法>
本発明の疾病抗原特異的CTLとγδT細胞の同時誘導方法(以下、単に「本発明の誘導方法」とも言う)は、末梢血に疾病抗原とアミノビスホスホネートとを添加する工程と、末梢血の培養を行う工程とを含むことを特徴とする。
1)採血により末梢血を得る。量としては15~25mLを必要とする。これだけの量を得られれば、好適に培養することが可能である。ただし、培養開始時に十分な末梢血量であればこの範囲に限らず、また、採血するドナーの負担が少ないようであれば、採血量が多くなるほど疾病抗原特異的CTLとγδT細胞の回収細胞数は増加するので、より多くの採血量が好ましい。
2)例えば密度勾配遠心法により、末梢血単核球を得る。個数としては15~25mLの末梢血からはおおむね1~2×107個の末梢血単核球を得ることができる。
5)フラスコ、バッグ又はプレート中に播種された末梢血単核球に濃度が0.05~100μM、好ましくは0.1~30μMとなるようにアミノビスホスホネートを添加する。
抗原の形態としては、ペプチドや、タンパクなど適宜用いることができる。また、がん細胞又は感染症細胞の細胞融解物、アポトーシス細胞、ネクローシス細胞、及びそれらの熱処理物等を使用することができる。
抗原としては、患者由来のもの(例えば、患者から外科手術によって摘出された腫瘍組織等)でも、合成したものでも良い。合成ペプチドを利用すれば、自己のがん組織等から採取したがん抗原を使用する場合と比べ、患者の負担を少なくすることができる。
添加する量は、ペプチドであれば0.02~2μg/ml程度添加すれば良い。例えば2μg/mlを添加する。
7)IL-2を添加した後34~38℃、より好ましくは37℃で、2~10%、より好ましくは5%CO2存在下で培養する。この際、培養する細胞数に応じ、培養液を適宜添加する。更に、培養液の増加に伴い、IL-2の濃度が50~2000U/mL、より好ましくは400~1000U/mLとなるように適宜添加する。
本発明の医薬は疾病抗原特異的CTLとγδT細胞からなる医薬であって、末梢血に疾病抗原とアミノビスホスホネートとを培養開始時に添加して培養することにより得られる医薬である。
1)本発明の培養方法によって得られた細胞を遠心分離法等により回収する。
2)回収した細胞を洗浄液で洗浄する。洗浄液は、細胞と浸透圧が等しい等張液であることが好ましく、医薬品として使用可能な液体であればより好ましい。ここで、患者に投与することを考慮すると、例えば生理食塩水、PBS(phosphate buffered saline;リン酸緩衝生理食塩水)等を利用することが好ましい。
本発明の医薬に用いる疾病抗原特異的CTLとγδT細胞を優位に含むリンパ球集団の数は、投与方法、疾病の種類、患者の症状等に応じて適宜選択されるが、通常、108~1012個/人であることが好ましく、より好ましくは109個/人以上である。
4)ついで生理食塩水に懸濁して本発明の医薬を得る。本発明の医薬はがんや感染症を対象とした治療・予防剤として用いることができる。
本発明の治療・予防方法は末梢血に疾病抗原とアミノビスホスホネートとを培養開始時に添加して培養することにより得られた疾病抗原特異的CTLとγδT細胞を投与する治療・予防方法である。
1)本発明の培養方法によって得られた細胞を遠心分離法等により回収する。
2)回収した細胞を洗浄液で洗浄する。洗浄液は、細胞と浸透圧が等しい等張液であることが好ましく、医薬品として使用可能な液体であればより好ましい。ここで、患者に投与することを考慮すると、例えば生理食塩水、PBS(phosphate buffered saline;リン酸緩衝生理食塩水)等を利用することが好ましい。

4)ついで生理食塩水に懸濁して細胞懸濁液を得る。
1)健常人ドナーから末梢血を42ml採血し、血球分離用比重液を用いて末梢血単核球を分離した。
2)得られた末梢血単核球を、AIM-Vに懸濁した。
3)6well plate(SUMILON)に、8×106/4mLの末梢血単核球を播種した。IL-2を1000U/mL加え、更に、ゾレドロン酸(ZOMETA(登録商標))を5μM、ペプチドとしてMart-1(A27L、配列;ELAGIGILTV)を2μg/ml添加し、37℃、5%CO2濃度条件下で培養を開始した。
4)更に培養開始後にAB血清を10%添加した。
5)細胞の増殖に応じて、IL-2を1000U/ml含有するAIM-V、及び、AB血清を添加し14日間培養した。
6)上述のとおり、7日間もしくは14日間培養した後に得られた細胞群中の疾病抗原特異的CD8陽性T細胞の割合、またTCRVγ9を発現している細胞の割合を抗CD8抗体(BD Pharmingen)、T-Select HLA-A*0201 Mart-1 Tetramer ELAGIGILTV(MBL)、抗TCRVγ9抗体(ベックマン・コールター)、抗CD3抗体(ベックマン・コールター)、を用いて、Fluorescence-Activated Cell Sorter(以下FACSという、Epics XL-MCL ADC,ベックマン・コールター)により測定した。測定により得られた値を以下に示す。
以下の手順により疾病抗原の添加がγδT細胞上のCD56発現率に影響を与えないかを調べた。CD56は神経系細胞接着分子(Neural Cell Adhesion Molecule、N-CAM)のアイソフォームで、NK細胞のマーカーとして知られる接着因子である。γδT細胞の有する細胞傷害活性の指標となるマーカーの一つである。
2)得られた末梢血単核球を、AIM-Vに懸濁した。
3)12well plate(SUMILON)に、1.8×106/2.5mLの末梢血単核球を播種した。IL-2を1000U/mL加え、更に、ゾレドロン酸(ZOMETA)を5μM、ペプチドとしてMart-1(A27L)を2μg/ml添加し、37℃、5%CO2濃度条件下で培養を開始した。
4)更に培養開始後にAB血清を10%添加した。
5)細胞の増殖に応じて、IL-2を1000U/ml含有するAIM-V、及び、AB血清を添加し最大14日間培養した。
6)上述のとおり、最大14日間培養した後に得られた細胞群中のTCRVγ9を発現している細胞の割合、またはCD56を発現している細胞の割合を抗TCRVγ9抗体(ベックマン・コールター)、抗CD56抗体(ベックマン・コールター)、抗CD3抗体(ベックマン・コールター)、を用いて、FACS(Epics XL-MCL ADC、ベックマン・コールター)により測定した。測定により得られた値を表5に示す。
