摘要: 非病毒性肝病主要包括非酒精性脂肪性肝病、酒精性肝病、自身免疫性肝病和胆汁淤积性肝病等,近年来患病率呈上升趋势。胆汁酸G蛋白偶联受体5(TGR5)隶属于G蛋白偶联受体超家族,由初级和次级胆汁酸激活,在胆汁酸稳态、基础代谢、能量平衡和减轻炎症反应等方面均发挥重要的调控作用,是多种疾病的潜在治疗靶点。越来越多的证据表明,TGR5可改善肝脏胆汁酸及糖脂代谢,减轻肝脏炎症反应,减少肝脂肪变性,从而发挥保护肝脏的作用。本文就目前TGR5在非病毒性肝病领域中的基础研究进展作一综述,期冀对TGR5的研究发展有所补益。

Abstract: Non-viral liver diseases mainly include nonalcoholic fatty liver disease, alcoholic liver disease, autoimmune liver disease, and cholestatic liver disease, and the prevalence rate of non-viral liver diseases tends to increase in recent years. Takeda G protein-coupled receptor-5 (TGR5) belongs to the G protein-coupled receptor superfamily and is activated by primary and secondary bile acids. TGR5 plays an important regulatory role in bile acid homeostasis, basal metabolism, energy balance, and alleviation of inflammatory response and is a potential therapeutic target for many diseases. An increasing number of evidence has shown that TGR5 exerts a protective effect on the liver by improving bile acid and glycolipid metabolism in liver, alleviating liver inflammation, and reducing liver steatosis. This article reviews the recent advances in the basic research on TGR5 in the field of non-viral liver diseases, so as to facilitate the development of the research on TGR5. -
