摘要: 目的 探索腺相关病毒介导的IFN体外抑制HBV的效果,寻求治疗HBV感染的新策略。方法 3种质粒共转染制备重组病毒AAV-IFN,用AAV-IFN感染肝细胞系HepG2.2.15,感染后1、3、6和9d,qPCR检测HBV DNA;ELISA方法检测HBsAg和HBeAg含量;MTT法检测HepG2.2.15细胞增殖的情况。结果 AAV-IFN可通过抑制HepG2.2.15细胞增殖的方式显著抑制HBV的复制与表达(P<0.05)。结论 AAV-IFN是一种有潜力的抗HBV的药物。

Abstract: To identify the anti-HBV efficiency of AAV-IFN by infecting HepG2.2.15 cell line, and to develop a new strategy of curing hepatitis B. Method Firstly,recombinant vector was packaged into AAV by three plasmids co-transfection method; then AAV-IFNα infected HepG2.2.15 cell line, and samples were collected on the1st, 3rd,6th and 9th day; thirdly, The time-course of HBV DNA,HBsAg and HBeAg were detected by qPCR and ELISA. The proliferation of HepG2.2.15 cells detected by MTT. Result Recombinant AAV-IFN can significantly inhibit HBV replication and expression in vitro because of the proliferation of HepG2.2.15 cells inhibited by AAV6-IFNα(P<0.05). Conclusion AAV-IFN is a potential antiviral therapeuticsfor curing hepatitis B.
