Cell proliferation is necessary for proviral integration and productive infection of most retroviruses. Nevertheless, the human immunodeficiency virus (HIV) can infect non-dividing macrophages. This ability to grow in non-dividing cells is not specific to macrophages because, as we show here, CD4+ HeLa cells arrested at stage G2 of the cell cycle can be infected by HIV-1. Proliferation is necessary for these same cells to be infected by a murine retrovirus, MuLV. HIV-1 integrates into the arrested cell DNA and produces viral RNA and protein in a pattern similar to that in normal cells. In addition, our data suggest that the ability to infect non-dividing cells is due to one of the HIV-1 core virion proteins. HIV infection of non-dividing cells distinguishes lentiviruses from other retroviruses and is likely to be important in the natural history of HIV infection.
