Relative HIV Resistance In Kenyan Sex Workers Is Not Due To An Altered Prevalence Or Mucosal Immune Impact Of Herpes Simplex Virus Type 2 Infection.
(University of Nairobi, 2009-09)
Chronic infection by herpes simplex virus type 2 (HSV-2) increases HIV susceptibility, perhaps due to HSV-2-associated increases in activated mucosal immune cells. A small number of Kenyan female sex workers (FSWs) exhibit ...
HLA typing in a Kenyan cohort identifies novel class I alleles that restrict cytotoxic T-cell responses to local HIV-1 clades.
(University of Nairobi, 2002-09)
OBJECTIVES:
To investigate HLA class I allele frequencies in a Kenyan commercial sex worker (CSW) cohort, and to examine HIV-1 specific cytotoxic T lymphocyte (CTL) responses directed against epitopes derived from locally ...
Novel Interferon Regulatory Factor-1 Polymorphisms In A Kenyan Population Revealed By Complete Gene Sequencing
(University of Nairobi, 2004)
Variation in susceptibility to HIV-1 infection depends on numerous factors, and host genetic variation has been well-described as an important component. As a transcriptional regulator, interferon regulatory factor 1 (IRF-1) ...
Elevation Of Immune Activation In Kenyan Women Is Associated With Alterations In Immune Function: Implications For Vaccine Development.
(University of Nairobi, 2004-11)
The infectious burden leading to immune activation can vary between different populations and lead to various immune dysfunctions. We compared the effect of immune activation on apoptosis and T cell function in HIV uninfected ...
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 ...
Recombination following superinfection by HIV-1.
(University of nairobi, 2004)
Background: There is increasing recognition of recombinant HIV-1 strains globally, but it has been unclear whether recombination results from superinfection during untreated, chronic infection.
Objective: To search for ...
Construction of an infectious HIV type 1 molecular clone from an African patient with a subtype D/C Recombinant Virus.
(2004)
The majority of HIV-1 infections worldwide occur in Africa, where subtype B viruses are rare and intersubtype recombinants are common. Pathogenesis and vaccine studies need to focus on viruses derived from African patients, ...
Mucosal Neisseria gonorrhoeae coinfection during HIV acquisition is associated with enhanced systemic HIV-specific CD8 T-cell responses
(2008)
Background: The host immune response against mucosally acquired pathogens may be
influenced by the mucosal immune milieu during acquisition. As Neisseria gonorrhoeae
can impair dendritic cell and T-cell immune function, ...
Reduced rates of HIV acquisition during unprotected sex by Kenyan female sex wo kers predating population declines in H IV prevalence
(2008)
OBJECTIVES:
Female sex workers (FSWs) form a core group at high risk of both sexual HIV acquisition and secondary transmission. The magnitude of these risks may vary by sexual risk taking, partner HIV prevalence, host ...
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, ...
