Outline of Final Research Achievements |
The applicants aimed to elucidate the proliferative potential of synovium in arthritis from the viewpoint of apoptosis, chemotaxis and its functional relationship with inflammation. They aimed to develop previously unidentified factors by comprehensive gene expression analysis using RNA-seq. In synovial fibroblasts stimulated by the proinflammatory cytokine IL-1β, they found decreased gene expression of apoptosis-promoting factors. It was also confirmed that blood coagulation Factor XIII increased the expression of apoptosis inhibitory factor and chemokine genes.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、関節リウマチ(RA)の病態の中心である関節滑膜・滑膜線維芽細胞について、病態の解明を目的とした研究である。RAにおける滑膜線維芽細胞の特徴として、炎症性サイトカインの産生能、及び、旺盛な増殖能が挙げられる。本研究で得られた結果は、その病態を分子生物学的に説明することを可能にしており、炎症に伴う滑膜増殖の分子メカニズムを表現することでRAの病態解明に寄与すると考えられた。
