(A) Resting CD4 T cells were challenged with X4 HIV-1*GFP carrying the indicated Vpx WT variants and mutants, the latter incapable of interaction with the proteasome complex. Cells were challenged with identical TZM-bl infectious units and analyzed for GFP expression 3 d postinfection. Primary dot plots for GFP expression are shown for one representative donor. (B) Quantification of the percentage of GFP⁺ cells shown in A. Depicted are arithmetic means + SEM of analyses of eight (SIVmnd-2WT and SIVmnd-2H72A) and four donors (SIVrcmWT and SIVrcmQ75A), respectively, each measured in technical triplicates.
