Soluble TNF receptor type II (sTNF alpha RII) levels in serum, CD4 lymphocyte counts, and human immunodeficiency virus (HIV) burdens have each been correlated with HIV disease progression.
A mutant allele of CCR5 confers a high degree of resistance to HIV-1 infection in homozygous individuals and partial protection against HIV disease progression in heterozygotes.
In the HIV-1-positive Caucasian group, HLA-DQB1*0302 was associated with rapid HIV disease progression, but no marker was associated with a more favorable prognosis.
Effects of plasma HIV RNA, CD4+ T lymphocytes, and the chemokine receptors CCR5 and CCR2b on HIV disease progression in hemophiliacs. Hemophilia Growth and Development Study.
We conclude that plasma HIV RNA, CD4+ T lymphocytes, and CCR genotypes are correlated, and the protective affect of CCR2b against HIV disease progression is not completely explained by plasma HIV RNA or CD4+ T-lymphocyte number.
Genetic and phylogenetic analyses of the V3 region and the nef gene clones over time from uncultured peripheral blood mononuclear cells (PBMC) of American patients with varying HIV disease progression rates.
A 32-bp deletion of the CCR5 gene, leading to complete absence of functional CCR5 expression, has been associated with resistance to human immunodeficiency virus (HIV) infection in homozygotes and slower HIV disease progression in heterozygotes.
New polymorphisms have been recently identified in CX3CR1, a coreceptor for some HIV-1 strains, one of which was associated with a strong acceleration of HIV disease progression.
Single-nucleotide polymorphisms (SNPs) in the CCR2, CCR5, and CXCR4 genes as well as a 32-base pair deletion in the open reading frame of the CCR5 gene are associated with HIV disease progression among Caucasians and African-Americans in North America and Europe.
A mutation of the stromal cell-derived factor 1 gene (SDF-1 3'A) was shown to protect adults exposed to human immunodeficiency virus type 1 (HIV-1) from infection and to affect HIV disease progression in adults.
To examine hA3G's contribution to the protection against HIV disease progression in humans, we quantified hA3G mRNA levels in peripheral blood mononuclear cells from 6 HIV-uninfected and 25 HIV-infected subjects; the latter group included 8 long-term nonprogressors (LTNPs) and 17 progressors.
The findings are consistent with the hypothesis that CCR2-64I alleles may delay HIV disease progression without affecting susceptibility to infection among men.
Although polymorphisms of chemokine genes (SDF1, stromal cell-derived factor-1 and RANTES, regulated on activation, normal T cell expressed and secreted) and chemokine-receptor genes (CCR5, CCR2, CX(3)CR1) were shown to be associated with sensitivity to HIV infection and untreated HIV disease progression, their association with the response to highly active antiretroviral therapy (HAART) remains unclear.
