Decreased Immune Activation In Resistance To Hiv-1 Infection Is Associated With An Elevated Frequency Of Cd4(+)cd25(+)foxp3(+) Regulatory T Cells.
(University of Nairobi, 2009-05)
Human immunodeficiency virus (HIV)-resistant commercial sex workers provide a unique opportunity to study correlates of protection associated with natural resistance to HIV infection. Emerging data from studies of these ...
Cross-clade CD8(+) T-cell responses with a preference for the predominant circulating clade
(University of Nairobi, 2005-11)
Human immunodeficiency virus (HIV) genetic diversity is a major impediment to the design of a successful vaccine. Even if an HIV vaccine is proven effective, it remains to be seen whether this protection will extend to ...
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 ...
Genital levels of soluble immune factors with anti-HIV activity may correlate with increased HIV susceptibility
(University of Nairobi, 2008-10)
Despite the scale of the HIV pandemic, mucosal innate immune defenses prevent HIV infection after most sexual exposures. Several soluble immune factors with in vitro anti-HIV activity are present at the genital mucosa in ...
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 ...
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 ...
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 ...
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, ...
Cd4+ T Cell Responses In Hiv-exposed Seronegative Women Are Qualitatively Distinct From Those In Hiv-infected Women
(University of Nairobi, 2005-01)
The immune response of human immunodeficiency virus (HIV)-exposed seronegative (ESN) women may be qualitatively different from that in those infected with HIV (HIV(+)). In a cohort of female commercial sex workers in ...
