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 (ACE2) and facilitate viral entry into the host cell (2). Highly transmissible B.1.617 variant identified in India has mutations (∆Y145, ∆H146, E484K, D614G) in the spike protein. These mutations may result in increased transmissibility and re-infection or resistance to vaccine-elicited antibody. As new variants emerge, it is pivotal to evaluate their transmissibility, virulence and their possible tendency to escape antibody neutralization (3).
