为了正确理解SARS-CoV-2感染的传播和体液免疫的发展,研究人员评估了世界各地经历大流行的人的血清抗体的存在。这些研究依赖于使用来自病毒基因组的重组蛋白,以鉴定识别SARS-CoV-2表位的血清抗体。在这里,我们讨论了SARS-CoV-2抗体与其他四种引起人类疾病的β冠状病毒(MERS-CoV,SARS-CoV,HCoV-OC 43和HCoV-HKU 1)的完整刺突蛋白的交叉反应潜力。使用酶联免疫吸附试验(ELISA),我们检测了抗SARS-CoV-2抗体对其他四种冠状病毒的潜在交叉反应性,SARS-CoV-2和SARS /MERS-CoV抗体之间的交叉识别最强,正如基于其各自刺突蛋白序列同源性所预期的那样。对交叉反应性的进一步分析可以提供信息性数据,从而可能导致智能设计的泛冠状病毒疗法或疫苗。在线版本包含补充材料,可通过10.1007/s10875-021-00997-6获得。
In order to properly understand the spread of SARS-CoV-2 infection and development of humoral immunity, researchers have evaluated the presence of serum antibodies of people worldwide experiencing the pandemic. These studies rely on the use of recombinant proteins from the viral genome in order to identify serum antibodies that recognize SARS-CoV-2 epitopes. Here, we discuss the cross-reactivity potential of SARS-CoV-2 antibodies with the full spike proteins of four other betacoronaviruses that cause disease in humans, MERS-CoV, SARS-CoV, HCoV-OC43, and HCoV-HKU1. Using enzyme-linked immunosorbent assays (ELISAs), we detected the potential cross-reactivity of antibodies against SARS-CoV-2 towards the four other coronaviruses, with the strongest cross-recognition between SARS-CoV-2 and SARS /MERS-CoV antibodies, as expected based on sequence homology of their respective spike proteins. Further analysis of cross-reactivity could provide informative data that could lead to intelligently designed pan-coronavirus therapeutics or vaccines.
