Vpr increases cell killing during single-cycle infection of dividing Jurkat T cells. Jurkat T cells were mock infected or infected with VSV-G pseudotyped Vpr⁺ and Vpr⁻ HIV-1 viruses at MOIs of 5, 10, and 20 (respectively presented in panels a, b, and c). At different time intervals after infection, the number of viable cells was counted by trypan blue exclusion assay. The values represented means from duplicate samples. Similar data were obtained in two independent experiments.
