Evolving spike-protein N-glycosylation in SARS-CoV-2 variants

Authors : Baboo, Sabyasachi (2023)

It has been three years since SARS-CoV-2 emerged and the world plunged into a “once in a century” pandemic. Since then, multiple waves of infection have swept through the human population, led by variants that were able to evade any acquired immunity. The co-evolution of SARS-CoV-2 variants with human immunity provides an excellent opportunity to study the interaction between viral pathogens and their human hosts. The heavily N-gl...

HIV-1 CD4-binding site germline antibody–Env structures inform vaccine design

Authors : Dam, Kim-Marie A. (2023)

BG24, a VRC01-class broadly neutralizing antibody (bNAb) against HIV-1 Env with relatively few somatic hypermutations (SHMs), represents a promising target for vaccine strategies to elicit CD4-binding site (CD4bs) bNAbs. To understand how SHMs correlate with BG24 neutralization of HIV-1, we solved 4.1 Å and 3.4 Å single-particle cryo-EM structures of two inferred germline (iGL) BG24 precursors complexed with engineered Env-based immunogens lacking CD4bs N-glycans. St...
