Abstract:The chemokine receptor 5 (CCR5) serves as a co-receptor for the human immunodeficiency virus-1 (HIV-1) that facilitates viral entry into cells. Individuals who are homozygous for a 32 bp deletion of the CCR5 gene are resistant to infection, while for heterozygote carriers their HIV disease progression is delayed. To understand the variable HIV-1 disease course that still exists among rare carriers of this deletion, studies have focused on polymorphisms of the CCR5 gene. Nine different CCR5 human haplotypes (HH… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
