Human immunodeficiency virus type 1-infected women exhibit reduced interferon-gamma secretion after Chlamydia trachomatis stimulation of peripheral blood lymphocytes.
(2000)
Epidemiologic, animal, and in vitro models suggest an important role for interferon (IFN)-gamma in the clearance of Chlamydia trachomatis infection. IFN-gamma in the supernatants of in vitro-stimulated peripheral blood ...
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 ...
Immunogenicity Of Sequences Around Hiv-1 Protease Cleavage Sites: Potential Targets And Population Coverage Analysis For A Hiv Vaccine Targeting Protease Cleavage Sites.
(University of Nairobi, 2013-06)
Developing an effective preventative vaccine against HIV-1 has proved to be a great challenge. The classical and proven vaccine approach has failed so far or produced a modest effect, new approaches are needed. In this ...
Identification Of Four Novel Kir2dl2 Alleles And Two Novel Kir2dl3 Alleles In An East African Population.
(University of Nairobi, 2010-12)
We report four novel KIR2DL2 alleles and two novel KIR2DL3 alleles identified from an East African population using sequence-based typing. Sequencing and molecular cloning of exon 4 confirmed that the new 2DL2 alleles were ...
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, ...
Plummer Fa.HLA-A and HLA-B In Kenya, Africa: Allele Frequencies And Identification Of HLA- B*1567 And HLA- B*4426. Tissue Antigens.
(University of Nairobi, 2002-05)
HLA-A and HLA-B alleles of a population from Kenya, Africa were examined by sequencing exon 2 and exon 3 DNA and typing using a Taxonomy-based Sequence-analysis (TBSA) method. Extensive diversities were observed at both ...
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 ...
An Integrative Bioinformatic Approach For Studying Escape Mutations In Human Immunodeficiency Virus Type 1 Gag In The Pumwani Sex Worker Cohort.
(University of Nairobi, 2008-02)
Human immunodeficiency virus type 1 (HIV-1) is able to evade the host cytotoxic T-lymphocyte (CTL) response through a variety of escape avenues. Epitopes that are presented to CTLs are first processed in the presenting ...
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 ...
