摘要
Individuals who are heterozygous for the CCR5-Delta 32 mutation provide a natural model to examine the effects of reduced CCR5 expression on human immunodeficiency virus (HIV) persistence. We evaluated the HIV reservoir in 18 CCR5-Delta 32 heterozygotes and 54 CCR5 wild-type individuals during suppressive antiretroviral therapy. Cell-associated HIV RNA levels (P = .035), RNA to DNA transcriptional ratios (P = .013), and frequency of detectable HIV 2-long terminal repeat circular DNA (P = .013) were significantly lower in CD4(+) T cells from CCR5-Delta 32 heterozygotes. Cell-associated HIV RNA was significantly correlated with CCR5 surface expression on CD4(+) T cells (r(2) = 0.136; P = .002). Our findings suggest that curative strategies should further explore manipulation of CCR5.
