概述:

Novel coronavirus SARS-CoV-2 has caused the pandemic of the respiratory diseases (COVID-19) around the world since 2020 (1). The spike glycoprotein (S) of coronavirus, a type I transmembrane protein containing two subunits, S1 and S2 is known to bind with host cells through the interaction with angiotensin-converting enzyme 2 and facilitate viral entry into the host cell (2). D614G mutation in the SARS-CoV-2 spike protein has been associated experimentally with higher infectivity and clinically with higher viral loads in infected individuals (3). However, variants carrying both D614G and A222V mutations in the spike protein showed increased sensitivity to convalescent sera and sera elicited by inactivated-virus vaccines, which may be caused by the A222V mutation (4).
