In vitro HIV-1 infection in Macaca nemestrina PBMCs is blocked at a step beyond reverse transcription

Various stages in the lifecycle of HIV-1 were investigated in Macaca nemestrina and humans in vitro. Early events were analyzed by end point dilution DNA PCR with HIV-1 and SHIV infected PBMCs, while p24 and p27 ELISA assays were used to analyze core antigen production from infected cells. The results demonstrate that a step in the virus life cycle, beyond reverse transcription is blocked for HIV-1 infection in macaque cells.
