The current pandemic is caused by the coronavirus disease 2019 (COVID-19), which is, in turn, induced by a novel coronavirus (SARS-CoV-2) that triggers an acute respiratory disease. In recent years, the emergence of SARS-CoV-2 is the third highly pathogenic event and large-scale epidemic affecting the human population. It follows the severe acute respiratory syndrome coronavirus (SARS-CoV) in 2003 and the Middle East respiratory syndrome coronavirus (MERS-CoV) in 2012. This novel SARS-CoV-2 employs the angiotensin-converting enzyme 2 (ACE2) receptor, like SARS-CoV, and spreads principally in the respiratory tract. The viral spike (S) protein of coronaviruses facilities the attachment to the cellular receptor, entrance, and membrane fusion. The S protein is a glycoprotein and is critical to elicit an immune response. Glycosylation is a biologically significant post-translational modification in virus surface proteins. These glycans play important roles in the viral life cycle, structure, immune evasion, and cell infection. However, it is necessary to search for new information about viral behavior and immunological host's response after SARS-CoV-2 infection. The present review discusses the implications of the CoV-2 S protein glycosylation in the SARS-CoV-2/ACE2 interaction and the immunological response. Elucidation of the glycan repertoire on the spike protein can propel research for the development of an appropriate vaccine.

SARS-CoV-2 S-蛋白糖基化在 SARS-CoV-2/ACE2 与免疫反应相互作用中的作用

当前的大流行是由 2019 年冠状病毒病 (COVID-19) 引起的,而该病又是由引发急性呼吸道疾病的新型冠状病毒 (SARS-CoV-2) 引起的。近年来,SARS-CoV-2的出现是第三次影响人群的高致病性事件和大规模流行病。它继 2003 年的严重急性呼吸综合征冠状病毒 (SARS-CoV) 和 2012 年的中东呼吸综合征冠状病毒 (MERS-CoV) 之后。这种新型 SARS-CoV-2 采用血管紧张素转换酶 2 (ACE2) 受体,如SARS-CoV,主要在呼吸道中传播。冠状病毒的病毒刺突 (S) 蛋白促进了与细胞受体、入口和膜融合的附着。S 蛋白是一种糖蛋白,对引发免疫反应至关重要。糖基化是病毒表面蛋白中具有生物学意义的翻译后修饰。这些聚糖在病毒生命周期、结构、免疫逃避和细胞感染中起着重要作用。然而,有必要寻找有关 SARS-CoV-2 感染后病毒行为和免疫宿主反应的新信息。本综述讨论了 CoV-2 S 蛋白糖基化在 SARS-CoV-2/ACE2 相互作用和免疫反应中的影响。阐明刺突蛋白上的聚糖库可以推动研究开发合适的疫苗。有必要寻找有关 SARS-CoV-2 感染后病毒行为和免疫宿主反应的新信息。本综述讨论了 CoV-2 S 蛋白糖基化在 SARS-CoV-2/ACE2 相互作用和免疫反应中的影响。阐明刺突蛋白上的聚糖库可以推动研究开发合适的疫苗。有必要寻找有关 SARS-CoV-2 感染后病毒行为和免疫宿主反应的新信息。本综述讨论了 CoV-2 S 蛋白糖基化在 SARS-CoV-2/ACE2 相互作用和免疫反应中的影响。阐明刺突蛋白上的聚糖库可以推动研究开发合适的疫苗。
