HLA-G And Mother-child Perinatal HIVTransmission
(University of Nairobi, 2013-04)
Transplacental passage is a well-known phenomenon in HIV infection and immune responses at the maternal-fetal interface play a critical role in perinatal mother-to-child HIV transmission (MCHT). The high expression of HLA-G ...
The Shaping Of Modern Human Immune Systems By Multiregional Admixture With Archaic Humans
(University of Nairobi, 2011)
Whole genome comparisons identified introgression from archaic to modern humans. Our analysis of highly polymorphic human leukocyte antigen (HLA) class I, vital immune system components subject to strong balancing selection, ...
Influence of HLA Class I Haplotypes on HIV-1 Seroconversion and Disease Progression in Pumwani Sex Worker Cohort.
(University of Nairobi, 2014-07)
We examined the effect of HLA class I haplotypes on HIV-1 seroconversion and disease progression in the Pumwani sex worker cohort. This study included 595 HIV-1 positive patients and 176 HIV negative individuals. HLA-A, ...
Associations of human leukocyte antigen DRB with resistance or susceptibility to HIV-1 infection in the Pumwani Sex Worker Cohort
(2008)
OBJECTIVE:
A group of commercial sex workers in the Pumwani Sex Worker Cohort, established in 1985 in Nairobi, Kenya, remain HIV-1 uninfected despite heavy exposure to HIV-1 through active sex work. Previous studies showed ...
A Comparison Of Parallel Pyrosequencing And Sanger Clone-based Sequencing And Its Impact On The Characterization Of The Genetic Diversity Of Hiv-1.
(University of Nairobi, 2011)
BACKGROUND:
Pyrosequencing technology has the potential to rapidly sequence HIV-1 viral quasispecies without requiring the traditional approach of cloning. In this study, we investigated the utility of ultra-deep ...
Full-length Hiv Type 1 Proviral Sequencing Of 10 Highly Exposed Women From Nairobi, Kenya Reveals A High Proportion Of Intersubtype Recombinants.
(University of Nairobi, 2008-06)
Phylogenetic analysis has revealed that the current HIV/AIDS pandemic consists of a multitude of different viral clades and recombinant viruses. The predominant circulating HIV-1 clade in Kenya is A1; however, Kenya borders ...
Substantial Intrapatient Differences In The Breadth And Specificity Of Hiv-specific Cd8+ T-cell Interferon-gamma And Proliferation Responses.
(University of Nairobi, 2008-10)
HIV vaccine design and evaluation require a better understanding of protective immune responses. HIV-specific CD8+ T-cell responses have been characterized extensively using interferon-gamma (IFN-gamma) enzyme-linked ...
HLA class I associations with rates of HIV-1 seroconversion and disease progression in the Pumwani Sex Worker Cohort.
(2013)
Class I human leukocyte antigens (HLA) play an important role in the adaptive immune response by presenting antigens to CD8+ T cells. Studies have reported that several HLA class I alleles are associated with differential ...
Human leukocyte antigen-DQ alleles and haplotypes and their associations with resistance and susceptibility to HIV-1 infection
(2008)
Objectives: To determine the association of DQ antigens with resistance and susceptibility
to HIV-1.
Design: Despite repeated exposure to HIV-1, a subset of women in the Pumwani Sex
Worker cohort established in Nairobi, ...
