Hepatitis B virus (HBV) infection is still a worldwide health problem; however, the current antiviral therapies for chronic hepatitis B are limited in efficacy. The outcome of HBV infection is thought to be the result of complex interactions between the HBV and the host immune system. While the role of the adaptive immune responses in the resolution of HBV infection has been well characterized, the contribution of innate immune mechanisms remains elusive until recent evidence implicates that HBV appears to activate the innate immune response and this response is important for controlling HBV infection. Here, we review our current understanding of innate immune responses to HBV infection and the multifaceted evasion by the virus and discuss the potential strategies to combat chronic HBV infection via induction and restoration of host innate antiviral responses.
乙型肝炎病毒(HBV)感染仍然是一个全球性的健康问题;然而,目前用于慢性乙型肝炎的抗病毒疗法在疗效上受到限制。HBV 感染的结果被认为是 HBV 与宿主免疫系统之间复杂相互作用的结果。虽然适应性免疫反应在 HBV 感染的清除中所起的作用已经得到很好的描述,但直到最近有证据表明 HBV 似乎激活了先天免疫反应,并且该反应对于控制 HBV 感染很重要,先天免疫机制的贡献仍然难以捉摸。在这里,我们回顾了我们目前对 HBV 感染的先天免疫反应的理解,以及病毒的多方面逃避,并讨论了通过诱导和恢复宿主先天抗病毒反应来对抗慢性 HBV 感染的潜在策略。
