Association of human mannose receptor in sexual transmission of human immunodeficiency virus in serodiscordant couples.

ABSTRACT: HIV binds specifically to the human mannose receptor (hMR) on vaginal epithelial cells that are devoid of a conventional CD4 receptor. HIV binding to hMR on vaginal epithelial cells induces the production of matrix metalloproteinase 9 (MMP9) leading to degradation of the extracellular matrix, which may increase the risk of HIV entry into vaginal epithelial cells and further transmission into distal cells. Immunofluorescent localization of hMR on vaginal epithelial cells of seronegative females from the general population included the control group (n=52) and seronegative females from serodiscordant couples. There was PCR amplification of DNA from peripheral blood mononuclear cells (PBMCs) of the serodiscordant females for the CCR5 gene flanking the CCR5-Δ32 region; PCR amplification and se
