丙型肝炎病毒(HCV)感染全世界超过1.7亿人,是肝硬化和肝细胞癌的主要原因。大约20%的急性感染者清除了感染,而剩下的80%进展为慢性感染。因此,丙型肝炎提供了一个模型,其中成功和不成功的反应可以进行比较,以更好地了解人类对病毒感染的反应。我们的实验室研究HCV逃避适应性免疫应答的策略。本文综述了病毒突变对T细胞识别的影响,细胞表面抑制性受体在识别HCV中的作用,以及中和HCV感染的抗体的发展。了解什么是控制HCV的有效免疫应答,可能有助于开发HCV和其他慢性病毒感染的预防性和治疗性疫苗。
Hepatitis C virus (HCV) infects over 170 million people worldwide and is a leading cause of cirrhosis and hepatocellular carcinoma. Approximately 20% of those acutely infected clear the infection, whereas the remaining 80% progress to chronic infection. Hepatitis C thus provides a model in which successful and unsuccessful responses can be compared to better understand the human response to viral infection. Our laboratory studies the strategies by which HCV evades the adaptive immune response. This review describes the impact of viral mutation on T cell recognition, the role of cell surface inhibitory receptors in recognition of HCV, and the development of antibodies that neutralize HCV infection. Understanding what constitutes an effective immune response in the control of HCV may enable the development of prophylactic and therapeutic vaccines for HCV and other chronic viral infections.
