Comparison of the declines in CD4 counts in HIV-1-seropositive female sex workers and women from the general population in Nairobi, Kenya
(1995)
Studies from Kenya have reported rapid clinical disease progression among HIV-infected professional sex workers. The reasons for this rapid decline are unknown. To better understand factors influencing the course of disease, ...
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 ...
Molecular Definition Of Vaginal Microbiota In East African Commercial Sex Workers
(University of Nairobi, 2011-06)
Resistance to HIV infection in a cohort of commercial sex workers living in Nairobi, Kenya, is linked to mucosal and antiinflammatory factors that may be influenced by the vaginal microbiota. Since bacterial vaginosis (BV), ...
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 ...
