Broadly neutralizing antibodies (bnAbs) show promise in HIV prevention, yet viral escape remains a challenge. In the Antibody-Mediated Prevention (AMP) trials, the CD4 binding site (CD4bs) bnAb VRC01 blocked acquisition by VRC01-sensitive strains. However, its influence on viral evolution post acquisition is not fully...

This work shows that persistent germinal centers (GCs) support continued affinity maturation of founder clones and ipsilateral boosting preferentially engages these lineages in secondary GCs, and identifies disfavored mutational trajectories within the V3-glycan bnAb lineage, revealing intrinsic constraints on bnAb lin...

Ex vivo, ΔV1 gp120 reduced CCR5 expression on CD4+ T cells relative to WT gp120, consistent with the anti-inflammatory mucosal response by ΔV1-vaccine regimens in vivo, promotes an anti-inflammatory mucosal landscape less permissive to HIV seeding and dissemination following virus exposure.
