Figure 7: Depleting exosomes from HIV-1 suspensions increases CD4TL survival. CD4TL cultures were incubated for 2h with NL4-3Balenv viral suspensions with (filled bar) or without exosomes (open bar) then washed and cultured for four days. CD4TL RNA was reverse transcribed, purified and spliced TAT was quantified. Surviving cells were counted (panel c). Results are expressed as increases relative to the IgG1 control (n = 4).
