Outline of Research at the Start

肥満では腸内細菌叢の異常 (dysbiosis) と菌体成分リポ多糖 (LPS) の産生増加により代謝性高LPS血症をきたす. LPSはGut-Muscle axisやGut-Liver-Muscle axisのルートより,炎症性の骨格筋障害をきたし,サルコペニア(骨格筋減少+筋力低下) 形成に関与する. 生体ストレスセンサーの転写因子Nrf2はLPSによる炎症シグナル発生の抑制因子である. 各種Nrf2遺伝子改変マウスを用いて, 肥満, dysbiosisと代謝性高LPS血症による骨格筋障害の発症に対して, Nrf2の果たすサルコペニア形成の抑止に関する生体の防御機構について解明する.

Outline of Final Research Achievements

Hyper-endotoxicemia associated with obesity induces an inflammatory and/or oxidative stress in skeletal muscles and thereby underlies the development of sarcopenia via gut-muscle axis or gut-liver-muscle axis. On the other hand, Nrf2 acts as an in vivo regulator for oxidative stress. In this study, the roles of Nrf2 in muscles were investigated with special reference to an inhibition of sarcopenia. In obese mice, Nrf2 contributed to inhibit the atrophic changes of slow muscle fibers and to preserve the mitochondrial function in muscles. Moreover, Nrf2-related muscle preservation also contributed to prevent steatohepatitis via gut-liver-muscle axis in the mice.

Academic Significance and Societal Importance of the Research Achievements

肥満にサルコペニアを随伴したサルコペニア肥満は生命予後が不良であり,その抑止は重要な医療課題である.本研究では,肥満者がサルコペニアに至るルートに着目し,Nrf2がサルコペニアの形成に対して防御的に機能することを明らかにした.本研究の結果は,肥満者における骨格筋劣化に対して,Nrf2を標的とした新たな予防・治療法を構築する基盤となる可能性があり,今後の発展が期待される.
