Abstract

Hepatitis C virus (HCV) has evolved remarkable mechanisms that favor viral persistence by interfering with host innate and adaptive immune responses. These same mechanisms are likely to contribute to resistance to exogenously administered interferon used for HCV treatment. We review the host innate and adaptive immune responses in the context of HCV infection as well as the strategies by which these responses are subverted by the virus. In addition, the contribution of host factors, such as race and insulin resistance, to interferon non-responsiveness is discussed. Our progress in understanding the molecular underpinnings of interferon treatment failure in HCV infection has resulted in several promising and novel treatment strategies for HCV treatment non-responders.

摘要

丙型肝炎病毒(HCV)已经进化出了显著的机制,通过干扰宿主的先天性和适应性免疫反应来促进病毒的持续存在。这些相同的机制可能导致对用于HCV治疗的外源性干扰素产生耐药性。我们回顾了HCV感染背景下宿主的先天性和适应性免疫反应,以及病毒颠覆这些反应的策略。此外,还讨论了宿主因素,如种族和胰岛素抵抗,对干扰素无反应性的影响。我们在理解HCV感染中干扰素治疗失败的分子基础方面取得的进展,已经为HCV治疗无反应者带来了几种有前景的新型治疗策略。
