Outline of Research at the Start

関節リウマチは多数の関節に炎症を来し、関節機能の低下が問題となる病気である。近年、薬物治療の進歩により症状の改善する患者が増えてきているが、効果が不十分の患者が相当数存在することから、新たな治療法が必要である。本研究ではFGFR1と呼ばれる分子に注目し、炎症性関節炎の発症に関与する免疫機能をFGFR1が調節していると仮説を立てた。そこで実験的な関節炎および関節リウマチ患者の滑膜組織等を用いてその仮説を検証する。本研究により、既存の治療薬とは全く異なる新規の治療ターゲット候補を見出し、次世代の関節リウマチ治療戦略の基盤を構築する。

Outline of Final Research Achievements

It is well known that CD4+ T cells have roles in the pathogenesis of rheumatoid arthritis. However, the precise mechanisms are not well understood. We previously discovered that FGFR1 is a characteristic feature of CD4+ T cells from treatment-naive rheumatoid arthritis patient, and interestingly, the signal is diminished after the treatment.This study aimed to explore the characteristics of FGFR1-expressing CD4+ T cells in the patients with rheumatoid arthritis.
We performed single cell RNA-seq analysis and found FGFR1-expressing cells have activated phenotype. Consistent with this, flow cytometric analyses revealed that FGFR1-expressing CD4+ T cells have terminally differentiated phenotype with high production of inflammatory cytokines.
These results suggest that FGFR1-expressing CD4+ T cells have a potential to deteriorate the joint inflammation. Also, FGFR1+ CD4+ T cells may be a candidate for the novel therapeutic target.

Academic Significance and Societal Importance of the Research Achievements

関節リウマチは多数の関節に炎症が生じて、痛みや動きに支障が生じる疾患である。近年、薬物治療の進歩によって症状が改善する患者が増えているが、依然として症状の残る人もおり、新たな治療戦略が求められている。本研究ではFGFR1を発現するヘルパーT細胞に着目し、その機能を解析した。FGFR1陽性ヘルパーT細胞は活性化している形質を持っており、特に炎症物質を多く産生する機能があることが明らかとなった。今後、FGFR1陽性ヘルパーT細胞を標的とした治療法が確立されることで、既存の治療で改善しない関節リウマチ患者に新たな治療法を提案できる可能性がある。
