据估计,全世界有7100万人感染丙型肝炎病毒(HCV)。小动物模型的缺乏阻碍了抗病毒免疫机制的研究。在这里,我们表明,在挪威大鼠中发现的HCV相关的肝炎病毒可以建立高滴度嗜肝性感染的免疫学特征类似于在人类病毒性肝炎的实验室小鼠。虽然免疫受损的小鼠发展为持续感染,但免疫能力强的小鼠在3-5周内清除了病毒。急性清除是T细胞依赖性的,并与肝损伤有关。感染前CD 4 + T细胞的瞬时耗竭导致慢性感染,其特征在于高水平的肝内调节性T细胞和肝内CD 8 + T细胞上抑制性分子的表达。自然杀伤细胞控制早期感染,但不是病毒清除所必需的。该模型可能为肝脏抗病毒免疫机制提供深入的见解,这是开发HCV疫苗的先决条件。
An estimated 71 million people worldwide are infected with hepatitis C virus (HCV). The lack of small animal models has impeded studies of antiviral immune mechanisms. Here we show that an HCV-related hepacivirus discovered in Norway rats can establish high titer hepatotropic infections in laboratory mice with immunological features resembling those seen in human viral hepatitis. While immune-compromised mice developed persistent infection, immune-competent mice cleared the virus within 3–5 weeks. Acute clearance was T cell dependent and associated with liver injury. Transient depletion of CD4+ T cells prior to infection resulted in chronic infection, characterized by high levels of intrahepatic regulatory T cells and expression of inhibitory molecules on intrahepatic CD8+ T cells. Natural killer cells controlled early infection but were not essential for viral clearance. This model may provide mechanistic insights into hepatic antiviral immunity, a prerequisite for the development of HCV vaccines.
