Human immunodeficiency virus (HIV) and related viruses require coreceptors in addition to CD4 to infect target cells. Some G protein-coupled receptors in the chemokine receptor family, including CCR5, CXCR4, CCR3, CCR2b, and CCR8 in the chemokine receptor family, have been identified as HIV coreceptors. CXCR4 (also called Fusin, LESTR, HUMSTR) is a principal coreceptor for T-cell tropic strains of HIV-1. CXCR4 is also required for the infection by dual-tropic strains of HIV-1 and mediates CD4-independent infection by HIV-2. The alpha-chemokine SDF-1 is the ligand for EXCR4 and prevents infection by T-cell tropic HIV-1. CXCR4 associates with the surface CD4-gp120 complex before HIV enters target cells. The amino-terminal domain and the second extracellular loop of CXCR4 serve as HIV binding sites. CXCR4 messenger RNA levels correlate with HIV-1 permissiveness in diverse human cell types. Antibodies to CXCR4 may block HIV-1 and HIV-2 infection of human target cells.
