胆汁酸越来越被认为是全身代谢的关键调节剂。虽然胆汁酸长期以来一直被认为在营养吸收中发挥重要和直接的作用,但胆汁酸也可作为信号分子。胆汁酸与核激素受体法尼醇X受体(FXR)和膜受体G蛋白偶联胆汁酸受体5(TGR 5)的相互作用可调节肠促胰岛素激素和成纤维细胞生长因子19(FGF 19)分泌、胆固醇代谢和全身能量消耗。胆汁酸水平和分布在2型糖尿病中改变,并在减肥手术后增加,同时体重减轻,胰岛素敏感性和血糖控制改善。因此,使用胆汁酸结合树脂、TGR 5激动剂和FXR激动剂调节胆汁酸水平和信号传导可用作治疗人的肥胖症、2型糖尿病和代谢综合征的其它组分的有效治疗方法。
Bile acids are increasingly recognized as key regulators of systemic metabolism. While bile acids have long been known to play important and direct roles in nutrient absorption, bile acids also serve as signaling molecules. Bile acid interactions with the nuclear hormone receptor farnesoid X receptor (FXR) and the membrane receptor G-protein-coupled bile acid receptor 5 (TGR5) can regulate incretin hormone and fibroblast growth factor 19 (FGF19) secretion, cholesterol metabolism, and systemic energy expenditure. Bile acid levels and distribution are altered in type 2 diabetes and increased following bariatric procedures, in parallel with reduced body weight and improved insulin sensitivity and glycemic control. Thus, modulation of bile acid levels and signaling, using bile acid binding resins, TGR5 agonists, and FXR agonists, may serve as a potent therapeutic approach for the treatment of obesity, type 2 diabetes, and other components of the metabolic syndrome in humans.
