五种人类肝炎病毒引起全世界大多数急性和慢性肝病。在过去的25年中,丙型肝炎病毒(HCV)特别受到了极大的关注,因为它能够在大多数免疫功能正常的成年人中持续存在,并且缺乏保护性疫苗。在这里,我们研究先天性和适应性免疫反应的HCV感染。虽然HCV激活先天免疫应答,但它采用一套精心设计的机制来逃避基于干扰素(IFN)的抗病毒免疫。通过比较先天性和适应性免疫反应,丙型肝炎病毒与甲型和B型肝炎病毒,我们认为,延长先天免疫激活损害成功的适应性免疫反应的发展。比较免疫学还提供了对维持免疫保护的见解。最后,我们讨论了丙型肝炎病毒疫苗的前景和未来的研究需要的肝炎病毒。
Five human hepatitis viruses cause most acute and chronic liver disease worldwide. Over the past 25 years hepatitis C virus (HCV) in particular has received much interest because of its ability to persist in most immunocompetent adults and the lack of a protective vaccine. Here we examine innate and adaptive immune responses to HCV infection. Although HCV activates an innate immune response, it employs an elaborate set of mechanisms to evade interferon (IFN)-based antiviral immunity. By comparing innate and adaptive immune responses to HCV with those to hepatitis A and B viruses, we suggest that prolonged innate immune activation impairs the development of successful adaptive immune responses. Comparative immunology furthermore provides insights into the maintenance of immune protection. We conclude by discussing prospects for an HCV vaccine and future research needs for the hepatitis viruses.
