Human immunodeficiency virus type 1 (HIV-1) has been found in the vitreous of persons with AIDS. Here we investigated the susceptibility of human retinal pigment epithelial (RPE) cells to HIV-1 infection in culture and the effects of HIV-1 on the phagocytic function of the RPE. We found that 10 of 11 populations of RPE cells isolated from different fetal or adult eyes were susceptible to low-level replication of HIV-1/NL4-3 as determined by the detection of viral DNA and spliced viral RNA encoding envelope. HIV-1 infection was not inhibited by recombinant soluble CD4, suggesting that CD4 is not required for virus entry into RPE cells. RPE cells fused with target cells constitutively expressing HIV-1 envelope glycoproteins, indicating that HIV-1 enters cells by receptor-mediated fusion. Exposure to HIV-1 or recombinant gp120 caused a two- to four-fold increase in the binding and uptake of isolated rod outer segments by RPE cells. These findings introduce a new cell target of HIV-1 replication in the eye and indicate that RPE cells function aberrantly when exposed to HIV-1 or its envelope glycoprotein.
