每年约有80万人死于B型肝炎病毒(HBV)感染。在大约5%的感染成人中,免疫系统在对抗HBV感染方面无效,导致慢性B型肝炎(CH B)。CHB与肝细胞癌相关,可导致患者死亡。不幸的是,尽管目前针对CHB的治疗允许控制HBV感染,但它们无法实现病毒的完全根除。IFN家族的细胞因子代表先天免疫系统的一部分,并且是病毒清除的关键参与者。IFN分泌诱导干扰素刺激基因的表达,产生具有抗病毒特性并且对细胞自主免疫至关重要的蛋白质。IFN-α通常用作CHB的治疗方法。此外,IFN-γ已被确定为负责在急性感染期间根除HBV的主要IFN家族成员。在这篇综述中,我们总结了从HBV复制或感染的细胞或动物模型中获得的关于IFN-γ的潜在抗HBV作用的关键证据,特别关注一些IFN-γ诱导基因。
About 0.8 million people die because of hepatitis B virus (HBV) infection each year. In around 5% of infected adults, the immune system is ineffective in countering HBV infection, leading to chronic hepatitis B (CHB). CHB is associated with hepatocellular carcinoma, which can lead to patient death. Unfortunately, although current treatments against CHB allow control of HBV infection, they are unable to achieve complete eradication of the virus. Cytokines of the IFN family represent part of the innate immune system and are key players in virus elimination. IFN secretion induces the expression of interferon stimulated genes, producing proteins that have antiviral properties and that are essential to cell-autonomous immunity. IFN-α is commonly used as a therapeutic approach for CHB. In addition, IFN-γ has been identified as the main IFN family member responsible for HBV eradication during acute infection. In this review, we summarize the key evidence gained from cellular or animal models of HBV replication or infection concerning the potential anti-HBV roles of IFN-γ with a particular focus on some IFN-γ-inducible genes.
