Fig. 4. Effect of mutations in the CT on Env antibody sensitivity.

Fig. 4

a Antibody neutralization of pseudovirus containing the 92UG037.8 Env determined for non-neutralizing antibodies, including b6 (CD4 binding site; blue), 3791 (V3; cyan), and 17b (CD4-induced; purple), and trimer-specific bnAbs, including PG9 (orange), PG16 (red), and PGT145 (magenta). The CD4 binding site bnAb VRC01, used as a control antibody, is shown in green. b Antibody neutralization of pseudovirus containing the L702S-A756N-D759R mutant. Right panel shows the relative decrease of sensitivity to the trimer-specific bnAbs of double and triple mutants bearing the D759R. c Antibody neutralization of pseudovirus (upper panel) containing a larger number of mutations in the CT (lower panel). d Same as (c) but for the mutant with mutations on the opposite side of the CT–TMD interface. e Same as (c) but for the mutant containing TMD mutations that break the hydrophobic and hydrophilic TMD–CT interactions.
