Kinetics of in vitro productive infection of macrophages with T-tropic HIV-1.
Six-day MDMs cultured in the absence of cytokines (○, ■) or in the presence of IFN-γ (●) (A) or IL-6 (▪) (B) were infected with HIVLAI. Infected MDMs were cultured in the presence of cytokines. Viral replication was monitored by p24 measurements. Control cultures included uninfected MDMs (♦). Data represent 3 experiments performed with macrophages derived from different individuals.
