Outline of Research at the Start

本課題において申請者は、自己免疫性間質性肺炎病態形成の中心を担うT細胞、B細胞、マクロファージ、線維芽細胞を用いたエピゲノム解析を行い、TGF-βを介した相互作用という観点から疾患発症メカニズムを解明し、疾患層別化バイオマーカーの探索および個別化医療開発の基盤となる創薬ターゲットの探索を目指す。

Outline of Final Research Achievements

The aim of this study is to elucidate the mechanisms of progressive fibrosis in connective tissue disease (CTD) -associated interstitial lung diseases (ILD). First, we confirmed the synergistic effects of cytokines including TGF-β1 on fibroblast activation. Second, we identified a novel effector memory CD4+ T cell subset that highly expresses TGFB1 in the bronchoalveolar lavage fluid in ILD. ATAC-seq (Assay for Transposase-Accessible Chromatin using sequencing) revealed the epigenetic mechanisms that regulate the expression of TGFB1 on the CD4+ T cell subset. These findings indicate that the pro-fibrotic CD4+ T cell subset might play a pivotal role in the progression of lung fibrosis via TGFB1 production. Further detailed analysis of the pro-fibrotic CD4+ T cell induction mechanisms will provide a novel therapeutic target for CTD-associated ILD.

Academic Significance and Societal Importance of the Research Achievements

間質性肺炎は、肺胞以外の肺を支える間質部分を中心とした炎症および激しい線維化を来す疾患であり、代表的自己免疫疾患であるリウマチ・膠原病疾患の予後を規定する。本課題では、自己免疫性疾患患者の間質性肺炎の肺胞洗浄液より、線維化促進性のサイトカインを高発現する新規T細胞を同定し、その線維化促進メカニズムを明らかとした。本解析結果は、間質性肺炎治療の新規創薬ターゲット同定に繋がる可能性を内包している。
