紧密连接相关蛋白:胆汁淤积性肝损伤治疗的新靶点

Tight junctions-associated proteins:a novel therapeutic target for cholestatic liver injury

  • 摘要: 胆汁淤积性肝损伤的发生伴随着肝细胞极性的改变和胆汁酸稳态失衡。紧密连接(tight junctions,TJs)结构是存在于上皮细胞之间、维持细胞极性的一种特殊屏障结构,其在维持机体胆汁酸稳态中发挥着重要作用。本文以胆汁淤积性肝损伤为研究基础,从肝脏和肠道紧密连接结构出发,探讨该结构在胆汁淤积性肝脏疾病中的作用及其分子调控机制,系统介绍以紧密连接相关蛋白为靶点的胆汁淤积性肝脏疾病治疗药物的最新进展,以期寻找与紧密连接结构相关蛋白为靶点的潜在治疗药物。

     

    Abstract: The occurrence of cholestatic liver injury is accompanied by the alterations of hepatocyte polarization and bile acid homeostasis. Located in epithelial cells, tight junctions(TJs)are a special barrier structure which are important in maintaining permeability and bile acid homeostasis. Based on the fully analysis and discussion of TJs, the latest therapeutic drugs for cholestasis were summaried, which may provide new perspectives and potential therapeutic agents for the treatment of cholestatic liver injury.
