Research Abstract

臨床的検討として、(1)自己免疫性膵炎(AIP)、SC-AIP、PSC、他の慢性膵炎の各患者および健常人に対して、血清IL-6,IL-10,IL-17,TGF-βの測定をELISA法にて行うとともに、(2)末梢血の制御性T細胞(Treg)、Th17細胞、IL10-産生T細胞の解析をフローサイトメトリーにより、行った。その結果、Th17細胞、IL-17には、差異を認めなかったが、IL-10陽性細胞と制御性T細胞は、AIPで有意に増加していた。(3)膵・胆管・肝組織を用いて検討すると、IgG4陽性細胞、制御性T細胞がPSCに比して、AIP, SC-AIPにおいて有意に浸潤していた。(II)基礎的検討として、(1)LF,CA-II,PSTIなどの疾患関連抗原に特異的な自己免疫性膵炎マウスやpoly-IC免疫マウス膵炎の作成を行った。(2)膵炎自然発症WB/Kobラットの解析と骨髄由来幹細胞の移入による発症阻止実験、によりTregやTh17細胞の関与を明らかにしつつあるが、Th17の関与は低いことが示唆された。
