Outline of Research at the Start

急激に腎臓の機能が低下する急性腎障害に対しては、いまだ特異的な治療法は存在しない。近年、消化管ホルモンの投与が急性腎障害に対して保護的に働くことが動物実験で報告されているが、そのメカニズムは不明である。申請者は、過去の研究実績から、消化管ホルモンは神経系と免疫系の相互作用を介して急性腎障害に対して保護的に働く、という仮説を立て、本研究ではこの仮説が正しいかどうかを検証する。

Outline of Final Research Achievements

Administration of GI hormone X significantly ameliorated acute kidney injury in wild-type mice. The protective effect was completely abolished in splenectomized mice, suggesting that the spleen is necessary for the renoprotective effect of X. Administration of GI hormone X did not excite afferent vagus nerve. This finding suggests that the vagus nerve may not contribute to the kidney protection by X administration.

Academic Significance and Societal Importance of the Research Achievements

急性腎障害は急激な腎機能低下を特徴とし、入院患者の約1割、ICU患者の約半数が合併するとされる。急性腎障害があらゆる症例の予後を悪化させ、さらに急性腎障害を発症するとその後慢性腎臓病さらには末期腎不全に進展し得ることも大きな問題である。しかしこの急性腎障害に対する特異的な治療はいまだ存在せず、新たな治療戦略が求められている。このような背景から、本研究によって消化管ホルモンによる腎保護メカニズムが明らかになれば、新規の急性腎障害予防・治療戦略の開発につながり、社会的意義は大きいものと考えられる。
