摘要
干扰素除具有免疫调节作用外,还能通过直接抗病毒作用抑制乙肝病毒(hepatitis B virus,HBV)的复制。干扰素与细胞膜上的受体结合后,通过激活JAK-STAT途径、干扰素调节因子(IRFs)信号传导途径等,产生一系列细胞因子,参与调节HBV增强子Ⅰ和X启动子(EhnⅠ/Xp)的功能,同时诱导宿主细胞产生抗病毒蛋白,作用于HBV复制周期的不同环节而产生直接抗病毒作用。本文主要对这一机制进行综述。
In addition to immune regulation, interferon could suppress hepatitis B virus (HBV) replication through direct antiviral effect. After binding with the receptors on cell membrane, interferon directly inhibits HBV at different steps in HBV replication cycle by activating cell signaling cascades such as JAK-STAT pathway, interferon regulatory factor (IRFs) signaling pathway, and so on, followed by inducing a series of cytokines which are involved in regulation of the function of HBV enhancer Ⅰ / X promoter (Ehn Ⅰ / Xp). Also, interferon could induce the host cells to produce anti-viral proteins. This review describes the direct antiviral mechanism of interferon on HBV.
