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

Abstract

VRC01-class bNAbs against the CD4 binding site of HIV-1 Env are targets of vaccine design. Here, the authors structurally characterized germline versions of the VRC01-class bNAb, BG24, bound to Env. They reveal mechanisms of germline binding, informing the design of VRC01-class targeting immunogens.
