Background
12G5 binds specifically to both human and nonhuman cells that express recombinant CXCR4. 12G5 inhibits CD4-independent infection by some HIV-2 isolates, and preincubating cells with 12G5 abolishes syncytium formation. HIV-2/vcp-infected cells display a marked and selective reduction in 12G5 binding. 12G5 also inhibits induction of cell-to-cell fusion of CXCR4+ RD/CD4 cells by HIV-1 and HIV-2 strains.
