Hepatitis C virus (HCV) is resistant to the antiviral cytokine type I interferon, representing a major clinical problem. Garaigorta and Chisari (2009) reveal that HCV uses the activation of the ds-RNA-dependent protein kinase R, which phosphorylates and inhibits the translation initiation factor eIF-2 alpha, to block translation of interferon-stimulated genes.
丙型肝炎病毒（HCV）对抗病毒细胞因子 I 型干扰素具有抗性，这是一个主要的临床问题。Garaigorta 和 Chisari（2009）揭示了 HCV 利用双链 RNA 依赖的蛋白激酶 R 的激活，磷酸化并抑制翻译起始因子 eIF-2α，从而阻断干扰素刺激基因的翻译。
