TGR5是一种新兴的G蛋白偶联受体,被鉴定为胆汁酸的膜受体。TGR5的表达及其功能不同于先前鉴定的核胆汁酸受体farnesoid X受体(FXR)。这两种胆汁酸受体在维持胆汁酸稳态和介导胆汁酸信号传导方面相互补充。这两种受体也被证明在调节炎症和葡萄糖代谢中发挥作用。关于TGR5的一个有趣发现是它在能量代谢中的作用。褐色脂肪细胞组织(BAT)中TGR5表达的发现以及最近在成人体内BAT的证实表明,通过靶向TGR5增加产热可能是对抗肥胖的一种潜在方法。现就TGR5在能量代谢和葡萄糖稳态中的作用作一综述。
TGR5, an emerging G protein-coupled receptor, was identified as a membrane receptor for bile acids. The expression of TGR5 and its function are distinct from the previously identified nuclear bile acid receptor, farnesoid X receptor (FXR). These two bile acid receptors complement with each other for maintaining bile acid homeostasis and mediating bile acid signaling. Both receptors are also shown to play roles in regulating inflammation and glucose metabolism. An interesting finding for TGR5 is its role in energy metabolism. The discovery of TGR5 expression in brown adipocyte tissues (BATs) and the recent demonstration of BAT in adult human body suggest a potential approach to combat obesity by targeting TGR5 to increase thermogenesis. We summarize here the latest finding of TGR5 research, especially its role in energy metabolism and glucose homeostasis.
