CCR5-Δ32 (or CCR5-D32 or CCR5 delta 32) is an allele of CCR5. CCR5 Δ32 is a 32-base-pair deletion that introduces a premature stop codon into the CCR5 receptor locus, resulting in a nonfunctional receptor. CCR5 is required for M-tropic HIV-1 virus entry. Individuals homozygous (denoted Δ32/Δ32) for CCR5 Δ32 do not express functional CCR5 receptors on their cell surfaces and are resistant to HIV-1 infection, despite multiple high-risk exp… WebFeb 1, 2024 · C–C chemokine receptor 5 (CCR5) has been implicated in the regulation of multiple forms of learning and memory via its regulation on learning-related cell signaling … WebC-C chemokine receptor 5 (CCR5) has been implicated in the regulation of multiple forms of learning and memory via its regulation on learning-related cell signaling … jetwing and fountain colorado springs
