FIG. 4.

Fusogenic capacity and susceptibility to T-20. (A) Fusion of SF162 and P3 gp120-expressing 293T cells with CEMx174 5.25 M7 cells. Results shown are the means and standard errors from three independent experiments. (B) Inhibition of luciferase reporter virus fusion with HOS.CD4.CCR5 cells by T-20. Viruses and T-20 were incubated for 1 h at 37°C before addition to cells, and inhibition relative to viruses in the absence of drug was calculated. The means and standard errors from three independent experiments are shown.
