A number of new experimental HIV drugs, called entry inhibitors, have been designed to interfere with the interaction between CCR5 and HIV, including PRO140 (Progenics), Vicriviroc (Schering Plough), Aplaviroc (GW-873140) (Glaxo Smith Kline) and Maraviroc (UK-427857) (Pfizer).

A potential problem of this approach is that, while CCR5 is the major co-receptor by which HIV infects cells, it is not the only such co-receptor.

Haplotype analysis of 192 Caucasian chromosomes revealed strong linkage disequilibrium between CCR5 and two microsatellite loci.

However, this is consistent with the observation that cells expressing the CCR5-Δ32 variant protein lack both the CCR5 and CXCR4 receptors on their surfaces, thereby conferring resistance to a broad range of HIV variants including HIV X4.

The geographic cline of CCR5-Delta32 frequencies and its recent emergence are consistent with a historic strong selective event (e.g.

Evan Quon, Yves Sere, Christopher Beh, Anant Menon and co-authors eliminate contact sites between the endoplasmic reticulum and the plasma membrane in yeast, revealing their role in the regulation of phospholipid synthesis and phosphatidylinositol-4-phosphate turn-over.

HIV uses CCR5 or another protein, CXCR4, as a co-receptor to enter its target cells.

Several chemokine receptors can function as viral coreceptors, but CCR5 is likely the most physiologically important coreceptor during natural infection.
