Effects of in Vivo CD8+ T cell depletion on virus replication in rhesus macaques immunized with a live, attenuated simian immunodeficiency virus vaccine
(2000)
The role of CD8+ T lymphocytes in controlling replication of live, attenuated simian immunodeficiency virus (SIV) was investigated as part of a vaccine study to examine the correlates of protection in the SIV/rhesus macaque ...
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 ...
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, ...
Dramatic rise in plasma viremia after CD8+ T cell depletion in simian immunodeficiency virus-infected macaques
(1999)
To determine the role of CD8+ T cells in controlling simian immunodeficiency virus (SIV) replication in vivo, we examined the effect of depleting this cell population using an anti-CD8 monoclonal antibody, OKT8F. There was ...
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) ...
Evidence of two distinct subsubtypes within the HIV-1 subtype A radiation
(2001)
Members of HIV-1 group M are responsible for the vast majority of AIDS cases worldwide and have been classified on the basis of their phylogenetic relationships into nine roughly equidistant clades, termed subtypes. Although ...
Effect of recent thymic emigrants on progression of HIV-1 disease
(2000)
Background. The concentration of T-cell receptor-rearrangement excision DNA circles (TREC) in peripheral-blood T cells is a marker of recent thymic emigrant αβ T cells. We studied the predictive ability of measurements of ...
