Individuals heterozygous for the mutant allele have a greater than 50% reduction in functional CCR5 receptors on their cell surfaces due to dimerization between mutant and wild-type receptors that interferes with transport of CCR5 to the cell surface.Heterozygote carriers are resistant to HIV-1 infection relative to wild types and when infected, heterozygotes exhibit reduced viral loads and a 2-3-year-slower progression to AIDS relative to wild types.Das setzt aber voraus, dass sich öffentliche Dienst offensiv und richtig auf die Generation Z einstellt.

The tyrosine sulfated amino terminus of this co-receptor is the "essential determinant" of binding to the gp120 glycoprotein.CCR5 Δ32 has an (heterozygote) allele frequency of 10% in Europe, and a homozygote frequency of 1%.The CCR5 Δ32 allele is notable for its recent origin, unexpectedly high frequency, and distinct geographic distribution, which together suggest that (a) it arose from a single mutation, and (b) it was historically subject to positive selection.However, because there is still another co-receptor available, this indicates that lacking the CCR5 gene doesn't make one immune to the virus; it simply implies that it would be more challenging for the individual to contract it. Unlike CCR5, which the body apparently doesn't really need due to those still living healthy lives even with the lack of/or absence of the gene (as a result of the delta 32 mutation), CD4 is critical in the body's defense system (fighting against infection).Even without the availability of either co-receptors (even CCR5), the virus can still invade cells if gp41 were to go through an alteration (including its cytoplasmic tail), resulting in the independence of CD4 without the need of CCR5 and/or CXCR4 as a doorway.
