CCR5 promoter polymorphisms in a Kenyan perinatal human immunodeficiency virus type 1 cohort: Association with increased 2-year maternal mortality
(2001)The CCR5 chemokine receptor acts as a coreceptor with CD4 to permit infection by primary macrophage-tropic human immunodeficiency virus type 1 (HIV-1) strains. The CCR5Δ32 mutation, which is associated with resistance to ...

Cellular HIV-1 DNA levels in drug sensitive strains are equivalent to those in drug resistant strains in newly-diagnosed patients in Europe
(2010)Background HIV-1 genotypic drug resistance is an important threat to the success of antiretroviral therapy and transmitted resistance has reached 9% prevalence in Europe. Studies have demonstrated that HIV-1 DNA load in ...

A chemokine receptor CCR2 allele delays HIV-1 disease progression and is associated with a CCR5 promoter mutation
(1998)Viral and host factors influence the rate of HIV-1 disease progression. For HIV-1 to fuse, a CD4+ cell must express a co-receptor that the virus can use. The chemokine receptors CCR5 and CXCR4 are used by R5 and X4 viruses, ...

Effects of CCR5-Δ32, CCR2-64I, and SDF-1 3′ a alleles on HIV-1 disease progression: An international meta-analysis of individual-patient data
(2001)Background: Studies relating certain chemokine and chemokine receptor gene alleles with the outcome of HIV-1 infection have yielded inconsistent results. Objective: To examine postulated associations of genetic alleles ...

Evidence for recent selection of the CCR5-Δ32 deletion from differences in its frequency between Ashkenazi and Sephardi Jews
(2000)Recent studies have shown higher frequencies of the CCR5-Δ32 allele and the CCR5-A32/Δ32 genotype, which confers protection against HIV infection, in northern Europe as compared to Mediterranean countries. Here, we analyse ...

Global distribution of the CCR2-641/CCR5-59653T HIV-1 disease-protective haplotype
(2000)Objectives: Several natural polymorphisms in the genes for the human CC-chemokine receptors CCR5 and CCR2 are associated with HIV-1 disease. The CCR2-641 genetic variant [a G to A substitution resulting in a valine (V) to ...

HIV-specific cytotoxic T lymphocytes, HLA-A11, and chemokine-related factors may act synergistically to determine HIV resistance in CCR5 Δ32-negative female sex workers in Chiang Rai, northern Thailand
(2001)Understanding how highly HIV-exposed individuals remain HIV uninfected may be useful for HIV vaccine design and development of new HIV prevention strategies. To elucidate mechanisms associated with resistance to HIV ...

Investigation of substituent effect of 1-(3,3-diphenylpropyl)-piperidinyl phenylacetamides on CCR5 binding affinity using QSAR and virtual screening techniques
(2006)A linear quantitative-structure activity relationship model is developed in this work using Multiple Linear Regression Analysis as applied to a series of 51 1-(3,3-diphenylpropyl)-piperidinyl phenylacetamides derivatives ...

Persistent HIV-1 infection of natural killer cells in patients receiving highly active antiretroviral therapy
(2002)We have identified a subset of CD56+CD3- human natural killer (NK) cells that express CD4 and the HIV coreceptors CCR5 and CXCR4. These cells can be productively infected in vitro by both CCR5- and CXCR4-using molecular ...

A polymorphism in the regulatory region of the CC-chemokine receptor 5 gene influences perinatal transmission of human immunodeficiency virus type 1 to African-American infants
(1999)There are natural mutations in the coding and noncoding regions of the human immunodeficiency virus type (HIV-1) CC-chemokine coreceptor 5 (CCR5) and in the related CCR2 protein (the CCR2-64I mutation). Individuals homozygous ...

Use of coreceptors other than CCR5 by non-syncytium-inducing adult and pediatric isolates of human immunodeficiency virus type 1 is rare in vitro
(1998)We have tested a panel of pediatric and adult human immunodeficiency virus type 1 (HIV-1) primary isolates for the ability to employ the following proteins as coreceptors during viral entry: CCR1, CCR2b, CCR3, CCR4, CCR5, ...
