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 ...
CD8(+) lymphocytes respond to different HIV epitopes in seronegative and infected subjects.
(University of Nairobi, 2001-05)
HIV-1-specific cytotoxic T-lymphocyte (CTL) responses have been detected at a low frequency in many HIV-1-exposed, persistently seronegative (HEPS) subjects. However, it is unclear how CTLs could protect against HIV ...
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 ...
Associations of sexual risk taking among Kenyan female sex workers after enrollment in an HIV-1 prevention trial.
(2005-03)
BACKGROUND:
Female sex workers (FSWs) often lack the ability to negotiate safer sex and are at high risk for HIV-1 infection and sexually transmitted infections (STIs).
METHODS:
Seronegative FSWs were enrolled in an ...
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 ...
HIV-1 Env-specific cytotoxic T-lymphocyte responses in exposed, uninfected Kenyan sex workers: a prospective analysis.
(University of Nairobi, 2004-10-21)
The prospective significance of HIV-specific cytotoxic T lymphocyte (CTL) responses in highly exposed, persistently seronegative populations is unknown. In 1996-1997 we screened for CTL responses against HIV clade B Env ...
Coinfection with herpes simplex virus type 2 is associated with reduced HIV-specific T cell responses and systemic immune activation.
(University of Nairobi,, 2008)
BACKGROUND:
Chronic coinfection with herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus (HIV) has been associated with an increased HIV viral load and more rapid disease progression, perhaps related to ...
