While the cell surface protein receptor CD4 has been identified as the primary receptor for HIV, additional molecules, called coreceptors, are required for the virus to enter and infect a cell. Studies over the past decade have demonstrated that these coreceptors also determine the types of viral strains responsible for person-to-person transmission and the rate of onset of AIDS. For example, cells with the receptor CD4 typically are the target of T-tropic but not M-tropic HIV. T-tropic viruses emerge gradually in HIV-positive ...
