中文摘要: HBV感染可导致肝炎、肝硬化和肝细胞癌,目前无特效治疗药物,关键问题在于HBV感染致病机制不清楚。本实验室前期研究结果显示磷脂爬行酶1(PLSCR1)与HBsAg具有相互作用,且在体内外具有显著的抑制HBV复制的作用,提示PLSCR1在HBV感染中具有重要作用。本项目拟在前期工作基础上,深入研究PLSCR1与HBV复制的关系,并通过研究PLSCR1对HBV复制周期的影响、对细胞功能以及HBV相关细胞信号通路的影响、与HBsAg相互作用对HBV感染复制的影响等,揭示PLSCR1调控HBV复制的分子机制,为研究HBV宿主相互作用奠定基础,为临床HBV治疗提供新的思路。该研究对于阐明HBV感染致病机理、促进新型抗HBV药物研发具有重要的科学价值和现实意义。

英文摘要: Chronic HBV infection causes hepatitis, even liver cirrhosis and hepatocellular carcinoma(HCC).Few effective treatments have been developed.The mechanism of HBV infection is not yet clear. Previous study in our lab have showed the interaction between PLSCR1 and HBsAg and the antiviral activities against HBV by PLSCR1 proteins in vitro and vivo. Such results suggest that PLSCR1 might play the important roles in HBV infection. In this study, we will further study to validate the involvement of PLSCR1 in HBV replication. Then to clairify the molecular machanism of the inhibition of HBV replication by PLSCR1,we will study the effects of PLSCR1 on HBV replication cycles,HBV replication pathways and host cellular functions, and also study the effects of the interaction between PLSCR1 and HBsAg on HBV replication.In conclusion, our study will provide the new insight into the machanism associated with HBV-host iteractions. Furtheremore, our study will facilitate the development of novel anti-HBV therapeutic strategies.
