Peptide and sCD4 inhibition of pseudovirus bearing Envs with E560K/D/G mutations. The IC50 values for the N36, IZN36, T20 and sCD4 were determined for pseudoviruses with Envs containing various mutations in RC4 cells, normalized to the IC50 for the wild-type pseudovirus (LAIwt). Averages and SD values (error bars) of at least three independent experiments are shown. The susceptibility and dose-dependent curves of pseudoviruses with indicated mutation to N36 (a, b), IZN36 (c, d), T20 (e, f) and sCD4 (g, h) are shown. *p < 0.05 compared with LAIwt
