Ccr5 Coreceptor

Ccr5 Coreceptor is an important human cell-surface receptor involved in a variety of physiological processes, including immune cell trafficking and viral entry into cells. It is a G-protein coupled receptor (GPCR) that binds to chemokines, which are small signaling molecules involved in many immune-related processes. Ccr5 plays a major role in the early stages of infection with certain types of viruses, including HIV, and it is thus the target of the highly successful anti-HIV drugs maraviroc and vicriviroc. These drugs block the binding of HIV viruses to the Ccr5 receptor on human cells, thereby reducing their ability to replicate. Ccr5 is therefore a critical target for antiviral therapies, and its importance to public health cannot be understated.
