Abstract

The therapeutic armamentarium against HIV has recently gained a drug belonging to a novel class of antiretrovirals, the entry inhibitors. The last decade has driven an in-depth knowledge of the HIV entry process, unravelling the multiple engagements of the HIV envelope proteins with the cellular receptorial complex that is composed of a primary receptor (CD4) and a co-receptor (CCR5 or CXCR4). The vast majority of HIV-infected subjects exhibit biological viral variants that use CCR5 as a co-receptor. Individuals with a mutated CCR5 gene, both homo- and heterozygotes, appear to be healthy. For these and other reasons, CCR5 represents an appealing target for treatment intervention, although certain challenges can not be ignored. Promising small-molecule, orally bioavailable CCR5 antagonists are under development for the treatment of HIV-1 infection.
