Our understanding of the host factors that determine susceptibility and progression of HIV infection has been very limited. In particular, it has been not clear why some people remain uninfected being repeatedly exposed to HIV-1, and others who have been infected by HIV, remain clinically asymptomatic for long periods of time. Recently it has been demonstrated that mutated forms of a number of chemokine receptors that act as coreceptors for HIV-1 entry may account for some of these phenomena. Furthermore, chemokines such as RANTES and others, being the natural ligands for chemokine receptors, have been shown to be effective inhibitors of HIV-1 infection. In this review we discuss some of the genetic, immunological, virological and epidemiological data relevant to the very important role chemokines and chemokine receptors play in HIV pathogenesis with special reference to the increased susceptibility of the African host to HIV infection.
