The chemokine receptors CCR5 and CXCR4 are the two major coreceptors for HIV entry. Numerous efforts have been made to develop a new class of anti-HIV agents that target these coreceptors as an ...

In addition to switching to the coreceptor CXCR4, the virus can adapt to use CCR5 in the presence of the coreceptor blocker, or preexisting minority variants can emerge that use CXCR4.

Other targets for entry inhibitors include two co-receptors on the cell surface—CCR5 and CXCR4—which together with CD4 mediate virus binding and membrane fusion 3. As CCR5, but not CXCR4 ...

the CD4 receptor and a co-receptor (CCR5 or CXCR4). Once HIV has attached to both, its envelope can fuse with the host cell membrane and release viral components into the cell. CCR5 inhibitors prevent ...

An individual’s virus may be exclusively CCR5-tropic, CXCR4-tropic (using the other co-receptor), or dual- or mixed-tropic (able to use both pathways). CCR5 antagonists only work against CCR5-tropic ...

Both mutations affect the formation of a molecule called CCR5, which the virus uses to enter its victim's cells. Individuals resistant to HIV-1 infection were found to have two identical copies of ...

HIV infects cells by attaching to a protein on their surface, called CCR5. Some people have a genetic mutation that changes the shape of this protein, meaning HIV can no longer attach to their ...

Experiments using cells that expresses both CXCR4 and CCR5, such as human peripheral blood mononuclear cells, rarely result in the selection of drug-resistant viruses that change coreceptor usage.
