CD4 and infection: Following infection at an MOI of 0.1, all 45 IMC-LucR replicated in CD4 T-cells expanded from PBMC from both ART naive subjects living with HIV-1 (Figure 1, left panel) and HIV-1 uninfected subjects (Figure 1, right panel) determined by luminescence in relative light units (RLU) as a result of LucR protein expression following 8 days of culture of infected CD4 T-cells.
