Outline of Research at the Start

全身性強皮症(SSc)の主要病態は、過剰な臓器線維化・血管障害・自己免疫異常である。SSc病態における単球・マクロファージ(Mq)系細胞の重要視示されているが、その病態形成での制御機構は不明である。インターフェロン制御因子(IRF8)は、単球・Mqへの血球分化に必須の転写因子であり、これまで我々は、SSc病態におけるIRF8の関与に着目してきた。今回、IRF8を介した単球・Mq系細胞の分化・形質異常が、創傷治癒過程やSScの血管障害に影響を与えると考え、主として単球のIRF8発現を調節した創傷治癒モデルマウス・SScマウスを解析することで、SScの創傷治癒異常の病態解明を目指す。

Outline of Final Research Achievements

This study was aimed to evaluate whether IRF8 is involved in abnormal wound healing and vasculopathy as critical features of SSc pathology. An involvement of IRF8 in wound healing process was evaluated in full-thickness skin wound model and wound closure was further assessed in myeloid-specific IRF8 knockout mice (IRF8KO). Upregulation of IRF8 was observed in skin wound model of WT, suggesting IRF8 involvement in wound healing. Wound closure was significantly delayed in IRF8KO mice. Histological analysis found smaller granulation tissue in IRF8KO mice. mRNA levels of adhesion and angiogenesis-related factors such as S1pr1, GlyCAM1, and P-Selectin were upregulated and amphiregulin was downregulated in IRF8KO mice. Abnormal angiogenesis with enhanced number of small vessels was observed in IRF8 KO mice. The results suggest that IRF8 in myeloid lineage cells plays important roles in wound healing and may mimic a part of SSc pathology.

Academic Significance and Societal Importance of the Research Achievements

全身性強皮症は、血管障害と過剰線維化の双方が主要な病態であり、両者を一元化する病態解明、新規治療開発が重要な課題である。単球マクロファージ系細胞が、強皮症の病態に重要な関与をしていることはこれまでも示唆されており、我々は、その分化制御を行う転写因子に着目した解析を行ってきた。これまでの研究と今回の研究により、線維化と創傷治癒異常・血管異常の双方にIRF8が関与する可能性が示唆されている。強皮症の血管異常におけるIRF8の関与をさらに深く解明することで、新規治療開発に結び付けられる可能性がある。
