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, ...

Genetic analysis of human immunodeficiency virus type 1 strains in Kenya: A comparison using phylogenetic analysis and a combinatorial melting assay
(1999)We surveyed human immunodeficiency virus (HIV) subtype distribution from peripheral blood mononuclear cells (PBMCs) collected in 1995 from 24 HIV-1- infected Kenyan residents (specimens from predominantly male truck drivers ...

Genotyping HIV-1 and HCV strains by a combinatorial DNA melting assay (COMA)
(1998)Background: Human immunodeficiency virus type 1 (HIV-1) and hepatitis C virus (HCV) strains can be genetically classified into genetic lineages known as genetic types of subtypes according to phylogenetic analyses of ...

Measuring recent thymic emigrants in blood of normal and HIV-1-infected individuals before and after effective therapy
(1999)The role of the thymus in HIV-1 pathogenesis remains unclear. We developed an assay to quantify the number of recent thymic emigrants in blood based on the detection of a major excisional DNA byproduct (termed α1 circle) ...

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 ...

Quantitative analysis of serum neutralization of human immunodeficiency virus type 1 from subtypes A, B, C, D, E, F, and I: Lack of direct correlation between neutralization serotypes and genetic subtypes and evidence for prevalent serum-dependent infectivity enhancement
(1996)Human immunodeficiency virus type 1 (HIV-1) M group strains have been assigned to date to nine distinct genetic subtypes, designated A through I, according to phylogenetic analyses of nucleotide sequences of their env or ...

Article
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, ...

Use of real-time PCR and molecular beacons to detect virus replication in human immunodeficiency virus type 1-infected individuals on prolonged effective antiretroviral therapy
(1999)We have designed a novel, precise, and sensitive assay to measure unspliced (US) human immunodeficiency virus type 1 (HIV-1) mRNA in peripheral blood mononuclear cells of HIV-1-infected individuals by using real-time PCR ...
