With the search for a preventive/therapeutic HIV vaccine elusive, the presence of CCR-2 gene polymorphisms that delay disease progression and prolong the lives of the infected in the Kenyan population may contribute to the growing evidence that host genetic factors are important in predicting susceptibility to HIV-1 infection.
Here, we determined the association of the CCR5 promoter SNPs, the CCR5-Δ32 mutation, CCR2-V64I SNP, and HH frequencies with resistance/susceptibility to HIV-1 infection in a cohort of HIV-1-serodiscordant couples from Colombia.
Mutations in the encoding genes, such as CCR5-∆32, CCR2-64I and SDF1-3'A are shown to result in protective effects against HIV-1 infection and disease progression.
To investigate the main and epistatic effects of the CCR5 promoter and CCR2-V64I polymorphisms on HIV-1 infection in the Northern Han Chinese, subjects of 91 HIV-1-infected patients and 91 health controls were recruited.
It has been reported that the CCR5-Delta32, CCR2-64I and SDF1-3'A polymorphisms have protective effects against HIV-1 infection and can delay the progression of AIDS in European populations.
The CCR2-64I allele and especially the SDF1-3'A allele are predominant in the Bahraini population and may be associated with resistance to fast HIV-1 infection in Bahrainis, and thus their genotyping can be used for prognosis in HIV-infected individuals.
The aim of this study was to investigate the correlation of CCR5-Delta32, CCR2b-64I, and SDF1-3'A polymorphisms with susceptibility to HIV-1 infection through sexual transmission in Han Chinese.
However, other mutations in the CCR5, CCR2, CX(3)CR1, CXCL12 (SDF1), and CCL5 (RANTES) genes have been identified and associated with host resistance and/or susceptibility to HIV-1 infection and disease progression.
Effect of genetic variants of CCR2 and CCL2 on the natural history of HIV-1 infection: CCL2-2518GG is overrepresented in a cohort of Spanish HIV-1-infected subjects.
Mutations in genes encoding chemokine receptors and their ligands, viz., CCR5delta32, CCR2-64I and SDF1-3'A are implicated to have protective effects against HIV-1 infection and/or disease progression.
Four SNPs (CCR2-V64I, CCR5-2459, MIP1A+954, and IL2+3896) and specific haplotypes in the IL2 and CCR2/CCR5 regions were significantly associated with HIV-1 infection susceptibility in different genetic models.
The chemokine receptor polymorphisms CCR5Delta32, CXCL12 3'A, CCR2-64I and CCR5-59029 G/A have been demonstrated to affect HIV-1 infection and progression.
We studied the prevalence of genetic variations in CCR2, SDF1, and the CCR5 gene and its promoter region at positions 59029, 59353, and 59356 in a seroprevalent cohort of 1057 children with symptomatic HIV-1 infection in the United States.
However, the CCR5-59029A, CCR2-64I, stromal cell-derived factor (SDF)-1-3'A, RANTES (regulated on activation, normally T cell-expressed and -secreted)-403A, and RANTES-28G polymorphisms were not associated with resistance to HIV-1 infection.
Genetic influence of CCR5, CCR2, and SDF1 variants on human immunodeficiency virus 1 (HIV-1)-related disease progression and neurological impairment, in children with symptomatic HIV-1 infection.
We have tested lentiviral vectors expressing shRNAs targetting CCR5 in primary CD4 T cells from donors representing various CCR5 and CCR2 genetic backgrounds covering the full spectrum of CCR5 expression levels and permissiveness for HIV-1 infection.
The large number of novel mutations/SNPs identified, using the CCR2-DGGE assay, indicates the importance for comprehensive analysis of all candidate genes in host susceptibility to HIV-1 infection, specifically in the under-studied African-based populations.
