Outline of Annual Research Achievements

最近、本邦でも乾癬全体の14%に関節症性乾癬(PsA)患者がいることが報告された。PsAの約半数の症例に発症から2年以内に骨びらんや関節変形が出現することもわかってきた。PsA の約7割は皮膚症状が先行するため、皮膚科医は本症を早期診断、治療介入する責務がある。しかし、PsAの病態は未解明のままである。生物学的製剤が有効な症例がある一方、難治例も多く、病態解明とさらなる新規治療法の開発が期待されている。膿疱性乾癬の患者もしばしばPsAを併発する。ところで、同一ケージで複数匹のマウス(雄)を飼育するとよくファイティングするが、申請者らはIL36RN欠損マウス(雄)では、ファイティングによって関節の腫脹が生じるという驚くべき現象を観察した(野生型マウスではこの現象は生じない)「IL-36は関節炎に関与していない」という上記定説に一見逆説的にも思われるこの現象について、外傷に伴う感染から自然免疫が賦活化し関節の腫脹が起こった可能性があると考察し研究を進めた。具体的には、Toll様受容体4(TLR-4)に着目し、そのリガンドであるリポ多糖(LPS)をIL36RN欠損マウスの後足に皮下投与した。その結果、野生型に比べ、著明な腫脹・肥厚(付着部炎)を認めた。即ち、IL36RN欠損マウスの後足にTLR-4リガンドを注入することによってPsAの病態を誘導することに成功した。さらにTLR-4阻害薬治療効果があることを明らかにした(Shibata A, Sugiura K, et al, J Autoimmun 2017;80:28-38.)。
