mPML knockout increases HIV-1 LTR-driven GFP expression. PML-KO and WT MEFs were infected with increasing doses of HIV-1_NL-GFP and cells were maintained in culture for 2 days (a) or 10 days (b), followed by FACS analysis. The percentage of infected (GFP-expressing) cells and the mean fluorescence intensity (MFI) were measured at each time point (top and bottom panels, respectively) (**P < 0.01; ***P < 0.001; one-tailed paired Student’s t test)
