高致病性SARS冠状病毒(SARS-CoV)的出现重新点燃了人们对冠状病毒生物学和发病机制的兴趣。冠状病毒发病机制中的一个新兴主题是特定病毒基因与宿主免疫系统(特别是先天免疫系统)之间的相互作用是调节毒力和疾病结果的关键决定因素。以SARS-CoV为模型,我们将回顾冠状病毒感染与宿主先天免疫系统在体内相互作用的现有知识,然后讨论特定基因产物在细胞培养模型中拮抗宿主先天免疫应答的机制。我们的数据表明,SARS-CoV使用特定的策略来逃避和拮抗干扰素通路的传感和信号臂。我们通过确定未来的考虑点进行总结,这将极大地有助于我们理解冠状病毒致病和毒力的分子机制,以及人类和动物严重疾病的发展。
The emergence of the highly pathogenic SARS coronavirus (SARS-CoV) has reignited interest in coronavirus biology and pathogenesis. An emerging theme in coronavirus pathogenesis is that the interaction between specific viral genes and the host immune system, specifically the innate immune system, functions as a key determinant in regulating virulence and disease outcomes. Using SARS-CoV as a model, we will review the current knowledge of the interplay between coronavirus infection and the host innate immune system in vivo, and then discuss the mechanisms by which specific gene products antagonize the host innate immune response in cell culture models. Our data suggests that the SARS-CoV uses specific strategies to evade and antagonize the sensing and signaling arms of the interferon pathway. We summarize by identifying future points of consideration that will contribute greatly to our understanding of the molecular mechanisms governing coronavirus pathogenesis and virulence, and the development of severe disease in humans and animals.
