能量调节的不平衡导致代谢紊乱,如肥胖和糖尿病。饮食在维持身体能量平衡中起着至关重要的作用,不仅作为能量来源,而且作为一种信号形式。除了葡萄糖外,哺乳动物还利用短链脂肪酸(SCFA)作为代谢燃料,而短链脂肪酸是由结肠细菌发酵膳食纤维产生的。SCFAs在能量调节中的作用仍不清楚,尽管葡萄糖的作用已得到充分研究。最近,一种G蛋白偶联受体去磷酸化策略成功地将GPR41(也称为游离脂肪酸受体3或FFAR3)鉴定为SCFA的受体。GPR41在脂肪组织、肠道和外周神经系统中表达,并且参与SCFA依赖性能量调节。在这篇简短的综述中,我们重点介绍GPR41在宿主能量调节中的作用。
Imbalances in energy regulation lead to metabolic disorders such as obesity and diabetes. Diet plays an essential role in the maintenance of body energy homeostasis by acting not only as energy source but also as a signaling modality. Excess energy increases energy expenditure, leading to a consumption of it. In addition to glucose, mammals utilize short-chain fatty acids (SCFAs), which are produced by colonic bacterial fermentation of dietary fiber, as a metabolic fuel. The roles of SCFAs in energy regulation have remained unclear, although the roles of glucose are well-studied. Recently, a G-protein-coupled receptor deorphanizing strategy successfully identified GPR41 (also called free fatty acid receptor 3 or FFAR3) as a receptor for SCFAs. GPR41 is expressed in adipose tissue, gut, and the peripheral nervous system, and it is involved in SCFA-dependent energy regulation. In this mini-review, we focus on the role of GPR41 in host energy regulation.
