- SSc Systemic sclerosis

- the etiology of SSc is still unknown, but three abnormalities of autoimmunity, angiopathy, and fibrosis are largely involved.
- immune disorders extensive studies have been conducted on T cell activation and polarization in both SSc patients and animal models (Non-Patent Document 3).
- Non-Patent Document 4 it has been shown that CD4 + T cells infiltrate skin lesions in the early stages of SSc (Non-Patent Document 4). It has been shown that the infiltrated T cells highly express the activation marker (Non-Patent Document 5). Similarly, activation of T cells has been found in peripheral blood (Non-Patent Document 6). Furthermore, activated CD4 + T cells in SSc are biased towards T helper (Th) type 2 (Non-Patent Documents 3 and 7). In fact, the major Th2 cytokines (cytokines produced by Th2 cells), interleukin (IL) -4, IL-6, and IL-13, are overexpressed in the skin and serum of SSc patients (non-patented). Documents 8-11).

- Th2 cytokines have also been reported to be associated with skin and pulmonary fibrosis in bleomycin-induced SSc model (BLM-SSc) mice known as SSc-like animal models (Non-Patent Documents 12-13). Mechanically, these Th2 cytokines directly induce collagen production in fibroblasts (Non-Patent Documents 14 to 16). Furthermore, IL-4 and IL-6 differentiate naive CD4 + T cells into Th2 cells and sustain Th2 and fibrosis-promoting responses (Non-Patent Documents 17-18). Taken together, these reports suggest that Th2-dominance is an important immunological feature of SSc that promotes fibrosis.
- Th2-dominant diseases include IL-4, IL-6, IL-13, as well as IL-31, an IL-6 family of Th2 cytokines.
- IL-31 is highly expressed in Th2-dominant diseases such as allergic asthma, atopic dermatitis, and cutaneous T-cell lymphoma (Non-Patent Documents 19 to 24).
- SSc In relation to SSc, it has been reported that IL-31 expression is increased in the fibrotic lungs of BLM-SSc mice (Non-Patent Document 25).

マウスIL-31RAに対する中和抗体の例としては、配列番号:11に記載のアミノ酸配列を有する重鎖可変領域と、配列番号:12に記載のアミノ酸配列を有する軽鎖可変領域とを含む抗マウスIL-31受容体A機能遮断モノクローナル抗体が挙げられる。これら重鎖および軽鎖可変領域の塩基配列は、それぞれアクセッション番号LC554895およびLC554896として、DDBJ/EMBL/GenBank国際塩基配列データベースに登録されている。
野生型C57BL/6マウスをジャクソン研究所(バーハーバー、メイン州、米国)から購入した。ブレオマイシン(BLM、日本化薬株式会社、東京、日本)を1 mg/mlの濃度でリン酸緩衝生理食塩水(PBS)に溶解した。BLM誘発SScモデル(BLM-SSc)マウスを作成するために、既報(Yoshizaki A, Iwata Y, Komura K, et al. CD19 regulates skin and lung fibrosis via Toll-like receptor signaling in a model of bleomycin-induced scleroderma. Am J Pathol 2008;172:1650-63.)のように、雌マウスの背部の毛を剃り、そこに200μgのBLMを毎日皮下注射した。BLMの代わりにPBSで処置したマウス(PBS-ctrlマウス)をBLM-SScマウスの対照として使用した。IL-31シグナル伝達の遮断の影響を評価するために、抗マウスIL-31受容体A機能遮断モノクローナル抗体(重鎖可変領域:配列番号11;軽鎖可変領域:配列番号12;それぞれDDBJ/EMBL/GenBankアクセッション番号LC554895、LC554896として登録されている)、又はマウスIgG1κアイソタイプ対照(eBioscience、サンディエゴ、カリフォルニア州、米国)を、7日毎(1日目、8日目、及び15日目)に200 μgずつ腹腔内に注射した。本試験において使用したマウスはいずれも6週齢であった。各グループ5匹のマウスを試験した。
アッセイで使用するまで、血清サンプルを-80℃で凍結した。マウスにおけるIL-4及びIL-6の血清中濃度を、ELISAキット(R&D Systems)を用いて測定した。すべての実験を製造元の説明書に従って実施した。
皮膚及び肺組織をホルマリンで固定し、パラフィンに包埋し、ヘマトキシリン及びエオシンで染色して、組織学的評価に供した。表皮真皮接合部と真皮脂肪接合部との間の距離と定義される、真皮の厚さを計測した。肺線維化の重症度を、Ashcroftらの記載(Ashcroft T, Simpson JM, Timbrell V. Simple method of estimating severity of pulmonary fibrosis on a numerical scale. J Clin Pathol 1988;41:467-70.)のとおり、半定量的に評価した。簡潔に説明すると、グレードの判定基準は次のとおり:グレード0=正常な肺;グレード1=肺胞壁又は細気管支壁の最小限の線維性肥厚;グレード3=肺構造に明らかな損傷のない、中程度の壁の肥厚;グレード5=肺の構造に明確な損傷があり、線維帯又は小さな線維性の腫瘤形成を伴う線維化の増加;グレード7=構造の深刻な変形及び大きな線維性領域;及びグレード8=フィールドの完全な線維性閉塞。グレード2、4、及び6を、上記基準の間の中間像として使用した。
製造元の説明書に従ってRNeasyスピンカラム(Qiagen、クローリー、英国)を用いて、組織から全RNAを単離した。各サンプルの全RNAをcDNAへと逆転写させた。ABI Prism 7000 sequence detector(Applied Biosystems、フォスターシティ、カリフォルニア州、米国)を用いたSYBR greenリアルタイムPCRによって、遺伝子発現を定量化した。ロードしたcDNAの量を標準化するため、内在性コントロールとしてGAPDHを用いた。既報(Yoshizaki A, Iwata Y, Komura K, et al. CD19 regulates skin and lung fibrosis via Toll-like receptor signaling in a model of bleomycin-induced scleroderma. Am J Pathol 2008;172:1650-63.)のように、比較Ct法を用いて相対値(fold difference)を計算した。プライマーの配列は以下のとおり:

既報(Wen X, He L, Chi Y, et al. Dynamics of Th17 cells and their role in Schistosoma japonicum infection in C57BL/6 mice. PLoS Negl Trop Dis 2011;5:e1399.)のように、フローサイトメトリーによってCD4+ T細胞の分化を分析した。簡潔に説明すると、Th1、Th2、又はTh17細胞を検出するために、脾細胞を2×106個/mlでRPMI 1640培地に懸濁し、2 μMモネンシン(Invitrogen、カールスバッド、カリフォルニア州、米国)の存在下、5% CO2、37℃にて、25 ng/ml PMA(Adipogen、サンディエゴ、カリフォルニア州、米国)及び1 mg/mlイオノマイシン(Sigma、セントルイス、ミズーリ州、米国)で6時間刺激した。次に、サンプルの表面を抗CD3-PE mAb及び抗CD4-FITC mAb(eBioscience)で染色した。Cytofix/Cytopermバッファー(BD PharMingen、サンディエゴ、カリフォルニア州、米国)による固定化及び透過化処理後、Th1、Th2、又はTh17細胞を検出するために、サンプルの細胞内を、それぞれIFN-γ、IL-4、又はIL-17Aに対するAPC結合mAb(eBioscience)で染色した。アイソタイプをマッチさせたAPC結合mAb(eBioscience)を対照として使用した。Treg細胞を検出するために、製造元のプロトコルとしてMouse Regulatory T Cell Staining Kit(eBioscience)を使用した。簡潔に説明すると、2×106個/mlで懸濁した脾細胞の表面を、抗CD3-PE/Cy7 mAb、抗CD4-FITC mAb、及び抗CD25-APC mAb (eBioscience)を用いて染色した。その後Cytofix/Cytopermにて固定及び細胞膜透過処理を行い、細胞内を抗Foxp3-PE mAb又は対照としてラットIgG2a-PEを用いて染色した。サンプルを、FACS Verseフローサイトメーター(BD Biosciences、サンディエゴ、カリフォルニア州、米国)を用いて分析した。
データは平均±標準偏差として表す。2グループ間の比較にはマンホイットニーU検定を用いて統計分析を行った。P値が0.05未満の場合に有意とした。すべての分析はGraphPad Prism 7.03(GraphPad Software、ラ・ホーヤ、カリフォルニア州、米国)を用いて行った。
SScの発症におけるIL-31の役割を明らかにするため、抗IL-31RA機能遮断mAbで処置したBLM-SScマウスにおける線維化及びTh2偏倚を評価した。3週間にわたり、BLMを毎日皮下注射すると共に、抗IL-31RA mAbを毎週投与した(図1A)。アイソタイプ対照IgGと比べて、抗IL-31RA mAbはBLM-SScマウスの真皮の厚さを有意に減少させた(p<0.01;図1B)。また、抗IL-31RA mAbは、BLM-SScマウスの肺の線維化スコアを顕著に減少させる効果を有した(p<0.001;図1B)。皮膚及び肺組織におけるサイトカインmRNAの発現に関して、抗IL-31RA mAbは、BLM-SScマウスにおいて上方制御されていたIL-4、IL-6、IL-10、及びTGF-β1の発現を抑制した(図1C)。更に、抗IL-31RA mAbは、BLM-SScマウスの脾臓T細胞において、Th2細胞の割合(p<0.01)、及びTh2/Th1比(p<0.05)を有意に低下させたが、Th17/Treg比を低下させなかった(図2A)。また、抗IL-31RA mAbは、BLM-SScマウスにおける血清中IL-4及びIL-6の過剰産生を改善した(それぞれp<0.01及びp<0.001;図2B)。全体として、抗IL-31RA mAbは、BLMによって誘導される線維化及びTh2偏倚を有意に低減した。
