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.

WebDec 12, 2024 · The CCR5 in these cells was fully active as a chemokine receptor (Extended Data Fig. 2a), and formed a tight complex with HIV-1 gp120 in the presence of soluble CD4 (Extended Data Fig. 2b). WebA natural loss-of-function mutation CCR5-Δ32, preventing the mutated protein expression on the cell surface, renders homozygous carriers of the null allele resistant to HIV-1 infection. This phenomenon was leveraged in the development of … WebMar 4, 1997 · CXCR4 is the fusogenic receptor that promotes entry of T-tropic HIV-1 strains, while CCR5 allows entry of M-tropic HIV-1 strains (13–20). The importance of these findings recently has been underscored by the finding that individuals deficient in CCR5 remain uninfected in the face of high-risk exposure to virus (22–24).
