肝星状细胞凋亡信号途径及其药物治疗的研究进展

各种致病因素所致慢性肝损伤均可引起肝纤维化,肝星状细胞(hepatic stellate cells,HSC)的激活是肝纤维化发生发展的中心环节,促进其凋亡被认为是肝纤维化逆转的始动因素。HSC的凋亡机制十分复杂,调控活化HSC凋亡的信号转导途径研究甚少。目前已知的HSC凋亡信号途径主要包括线粒体途径、死亡受体途径和非死亡受体途径。基于这些信号转导途径,研究出选择性诱导HSC凋亡的药物将成为抗肝纤维化治疗的重要手段。该文将对HSC凋亡信号转导通路的最新进展进行综述,并对目前已知的具有促HSC凋亡作用的药物进行总结分类。

The research progress of hepatic stellate cell's apoptosis signaling pathway and the relative drugs

Liver fibrosis can be caused by chronic liver injury arising from various etiological factors.The activation of the hepatic stellate cell(HSC) is the central event in liver fibrosis,the apoptosis of which was the initiating factor for the reversal process.The apoptosis of HSC is very complicated.The signaling pathways lack of enough research in regulating and controlling and activating HSC's apoptosis.The apoptosis pathways as known currently mainly include mitochondrial pathway,death receptor pathway and non-death receptor pathway.Based on these signaling pathways,selectively inducing cell death of activated HSCs is becoming the new antifibrotic treatment.This review focuses on the new progress of HSC's apoptosis signaling pathways,and summarizes the drugs that have the effect of inducing HSC apoptosis.
