摘要
丙型肝炎是由丙型肝炎病毒(hepatitis C virus,HCV)引起的传染性疾病,是慢性肝病的主要原因之一.本文系统阐述病毒编码蛋白通过直接与细胞内重要调节分子结合,以病毒-宿主细胞相互作用方式影响细胞重要的信号通路,导致细胞增殖、分化等发生异常,干扰机体免疫防御功能,削弱宿主对HCV感染细胞的抗病毒应答,有利于慢性持续性感染的建立,最终促使HCV相关肝病的发生和发展.加强对病毒蛋白生物学功能的研究,将有助于探讨HCV致病机制和免疫逃逸机制,对HCV特异靶向药物和治疗性疫苗的研究和开发也具有重要的意义.
Hepatitis C virus (HCV) is a major causative agent of chronic hepatitis,liver cirrhosis and hepatocellular carcinoma.At present,the molecular pathogenesis of HCV-induced liver diseases is largely unknown.This review will highlight recent results providing an idea of how HCV structural and non-structural proteins affect RNA replication,viral particle assembly and release,and how these proteins interfere with the intracellular signaling pathways and finally evade host defense.Elucidation of the molecular by which HCV regulates host response may facilitate revealing targets for novel therapeutic vaccines and drugs.
