Enhancement of SARS-CoV-2 Infection via Crosslinking of Adjacent Spike Proteins by N-Terminal Domain-Targeting Antibodies

The study published in Viruses journal provides new insights into the interaction between the spike protein of SARS-CoV-2 and certain human antibodies. These antibodies target the N-terminal domain (NTD) of the spike protein, which is a site away from where the virus binds to the host cell’s ACE2 receptor. Interestingly, these NTD-targeting infection-enhancing antibodies (NIEAs) were found to augment the virus’s ability to bind ACE2, thus enhancing infection. This effect is notable because it occurs independently of the antibody’s crystallizable fragment (Fc) region, differentiating it from other known antibody-dependent enhancement (ADE) mechanisms​​​​. Key Findings: Implications and Conclusion: This study not…
