Exogenous T H 2-type cytokines, IL-10 and TGF-β, have inhibitory effects on HIV-1 replication in HCs. HCs were left untreated or pretreated for with IL-10, TGF-β, TNF-α, IFN-γ, IL-4 and IL-6 prior to infection with HIV-1BaL. HIV-1 replication was measured in the cell supernatants by HIV-1 p24 viral antigen ELISA. Data shown are expressed as the mean ± SE of triplicate samples and are representative of 3 independent experiments from different donors (* p < 0.05, **p < 0.01).
