摘要: 肠道菌群紊乱破坏宿主免疫系统的平衡。肠道菌群代谢产生许多与宿主相互作用的生物活性分子,典型代表是次级胆汁酸(SBAs)。SBAs通过结合膜受体和核受体,例如武田G蛋白偶联受体5(TGR5)和法尼醇X受体(FXR),参与调控能量代谢和炎性反应相关基因的表达,对维持宿主免疫稳态具有重要意义。

Abstract: Disturbances of gut microbiota may affect the balance of the host immune system. The metabolism of gut microbiota produces many bioactive molecules interacting with host, typically secondary bile acids (SBAs). SBAs are involved in regulating the energy metabolism and the expression of inflammatory response-related genes by binding to membrane receptors and nuclear receptors, such as takeda G protein-coupled receptor (TGR5) and farnesol X receptor (FXR), which are essential for maintaining host immune homeostasis.

Key words: gut microbiota, secondary bile acids, immune regulation
