Non-neutralizing antibodies and bnAbs to HIV-1 Env vaccine candidates. (A) Non-neutralizing and bnAbs used in this study with their specificities are listed in the table. (B) The crystal structure of BG505 SOSIP.664 trimer in a side view (left) and top view (right), and the location of bnAb epitopes: apex, V1-V2 loops (blue), CD4 binding site (green), high mannose patch/V3 (pink), and the gp41 ectodomain (orange). (C) Neutralization breadth as presented by neutralization coverage (%) (y-axis) of large panels of global isolates and potency (median IC50, in μg/mL) (x-axis) of bnAbs as determined previously.5,25 bnAbs, broadly neutralizing antibodies.
