缺乏有效根除乙型肝炎病毒(HBV)的药物及技术手段是限制HBV感染无法治愈的瓶颈.成簇的规律间隔短回文重复序列及其相关蛋白9系统是近年来新兴的对特定基因位点进行编辑的技术,可以特异性靶向HBV共价闭合环状DNA,有效抑制HBV DNA复制、调控HBV功能蛋白表达,有望成为彻底根除HBV的强有力基因治疗工具.如何利用成簇的规律间隔短回文重复序列及其相关蛋白9系统实现对HBV基因组高效靶向修饰,从而达到根治HBV感染的目的已经成为当前国内外学者关注的焦点.现结合国内外最新研究成果,重点总结成簇的规律间隔短回文重复序列及其相关蛋白9基因编辑技术在抗HBV感染治疗中应用的最新进展,阐述其作为彻底根治HBV感染方案的潜在可能和挑战.“,”A lack of effective drags and technical means to eradicate hepatitis B virus (HBV) is a bottleneck that limits the ability to fully cure HBV infection.Recently,genome-editing technology based on clustered regularly interspaced short palindromic repeats-associated protein 9 is an emerging technique for editing specific gene loci,which can specifically target HBV covalently closed circular DNA,effectively inhibits HBV DNA replication and regulates HBV functional protein expression,and is expected to become a powerful gene therapy tool for the complete eradication of HBV.Considering this,it has become the focus of attention for scholars at home and abroad that how to use clustered regularly interspaced short palindromic repeats-associated protein 9 to accomplish modification of HBV genomes for complete eradication of HBV.This paper summarizes the latest progress based on the latest research results at home and abroad in the application of clustered regularly interspaced short palindromic repeats-associated protein 9 gene editing technology in anti-HBV infection treatment,and expounds its potential and challenges as a radical cure for HBV infection.
