血浆蛋白质组学揭示COVID-19的生物标志物和发病机理

中国科学院武汉病毒所周溪等研究人员合作利用血浆蛋白质组学鉴定出COVID-19的生物标志物和发病机理。相关论文于2020年10月20日在线发表在《免疫》杂志上。

通过对包括非幸存者和从轻度或严重症状中恢复的幸存者在内的COVID-19患者队列进行血浆蛋白质组学分析,研究人员分析了宿主对COVID-19的反应,并发现了血浆蛋白的许多COVID-19相关改变。研究人员开发了一种基于机器学习的方法,用以识别11种蛋白质作为生物标志物和一组生物标志物组合,这些标志物已通过独立研究组验证并准确区分和预测了COVID-19结果。一些生物标记通过在更大队列中使用ELISA得以进一步验证。
 
这些显著改变的蛋白质(包括生物标记物)介导可能有助于发病机理的病理生理途径,例如免疫或炎性反应、血小板脱粒和凝结以及新陈代谢。这些发现提供了有关COVID-19生物标记物的宝贵知识,并阐明了COVID-19的发病机理和潜在的治疗靶标。
 
据介绍,COVID-19大流行是全球性的公共卫生危机。然而,关于COVID-19的发病机理和生物标志物知之甚少。

Abstract: The COVID-19 pandemic is a global public health crisis. However, little is known about the pathogenesis and biomarkers of COVID-19. Herein, we profiled host responses to COVID-19 by performing plasma proteomics of a cohort of COVID-19 patients including non-survivors and survivors recovered from mild or severe symptoms, and uncovered numerous COVID-19-associated alterations of plasma proteins. We developed a machine learning-based pipeline to identify 11 proteins as biomarkers and a set of biomarker combinations, which were validated by an independent cohort and accurately distinguished and predicted COVID-19 outcomes. Some of the biomarkers were further validated by ELISA using a larger cohort. These markedly altered proteins, including the biomarkers mediate pathophysiological pathways such as immune or inflammatory responses, platelet degranulation and coagulation, and metabolism, that likely contribute to the pathogenesis. Our findings provide valuable knowledge about COVID-19 biomarkers, and shed light on the pathogenesis and potential therapeutic targets of COVID-19.
