美国加州大学旧金山分校Nevan J. Krogan等研究人员合作利用宿主与冠状病毒蛋白相互作用网络，揭示出泛病毒疾病机理。相关论文于2020年10月15日在线发表在《科学》杂志上。
据研究人员介绍，由SARS-CoV-2冠状病毒引起的COVID-19大流行是对公共卫生和全球经济的重大威胁。SARS-CoV-2与致死性更强、更不易传播的冠状病毒SARS-CoV-1和MERS-CoV密切相关。
研究人员对所有三种病毒进行了病毒与人类的蛋白质-蛋白质相互作用以及病毒蛋白质定位分析。随后的功能遗传筛选确定了在功能上影响冠状病毒增殖的宿主因子，包括Tom70（一种线粒体伴侣蛋白，可与SARS-CoV-1和SARS-CoV-2 Orf9b相互作用），研究人员使用cryo-EM在结构上表征了这种相互作用。 将经过基因验证的宿主因素与COVID-19患者的遗传数据和医疗账单记录相结合，可以确定重要的分子机制和潜在的药物治疗方法，这值得进一步的分子和临床研究。

Abstract: AbstractThe COVID-19 (Coronavirus disease-2019) pandemic, caused by the SARS-CoV-2 coronavirus, is a significant threat to public health and the global economy. SARS-CoV-2 is closely related to the more lethal but less transmissible coronaviruses SARS-CoV-1 and MERS-CoV. Here, we have carried out comparative viral-human protein-protein interaction and viral protein localization analysis for all three viruses. Subsequent functional genetic screening identified host factors that functionally impinge on coronavirus proliferation, including Tom70, a mitochondrial chaperone protein that interacts with both SARS-CoV-1 and SARS-CoV-2 Orf9b, an interaction we structurally characterized using cryo-EM. Combining genetically-validated host factors with both COVID-19 patient genetic data and medical billing records identified important molecular mechanisms and potential drug treatments that merit further molecular and clinical study.
