WebCCR5 antagonists inhibit HIV-1 entry by blocking the interaction of HIV-1 with the CCR5 cellular receptor. In patients with established HIV-1 infection, some viral strains use an alternative coreceptor for HIV-1 entry, CXCR4; CCR5 antagonists are not effective in patients harboring these viral strains. WebFeb 9, 2006 · The knowledge of this mechanism of HIV entry into cells has resulted in the development of a new class of HIV therapy called entry inhibitors, which blockade the CCR5 or CXCR4 co-receptors and prevent ongoing HIV infection of susceptible CD4+ cells.
