摘要：

We investigated the fate of human immunodeficiency virus type 1 (HIV-1) viral DNA in infected peripheral blood lymphocytes and immortalized T-cell lines by using a replication-defective HIV-1. We observed that integrated HIV-1 DNA and viral gene expression decrease over time. A frameshift mutation in vpr resulted in maintenance of the HIV-1 provirus and stable persistence of viral expression. Transfection of vpr together,vith the neomycin resistance gene in the absence of other viral genes decreased the formation of geneticin-resistant colonies, indicating either a cytotoxic or a cytostatic effect upon cells. Therefore, maintenance of HIV-1 infection within an infected proliferating population is due to two competing processes, the rate of viral spread and the degree of cell growth inhibition and/or death induced by Vpr.
