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 ...
Female-to-male infectivity of HIV-1 among circumcised and uncircumcised Kenyan men
(University of Nairobi,, 2005)
BACKGROUND:
A lack of male circumcision has been associated with increased risk of human immunodeficiency virus type 1 (HIV-1) acquisition in a number of studies, but questions remain as to whether confounding by behavioral ...
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 ...
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 ...
Relationship between markers of HIV-1 disease progression and serum beta-carotene concentrations in Kenyan women.
(University of Nairobi,, 2007)
Observational studies have suggested that low serum beta-carotene concentrations may influence HIV-1 disease progression. However, randomized trials have not demonstrated beneficial effects of beta-carotene supplementation. ...
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 ...
Increased interleukin-10 in the the endocervical secretions of women with non-ulcerative sexually transmitted diseases: a mechanism for enhanced HIV-1 transmission?
(1999)
OBJECTIVE:
Although non-ulcerative sexually transmitted diseases (STD) and bacterial vaginosis are implicated as cofactors in heterosexual HIV-1 transmission, the mechanisms have not been defined. Recent in vitro data ...
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 ...
Vitamin A supplementation and genital shedding of herpes simplex virus among HIV-1-infected women: a randomized clinical trial.
(University of Nairobi,, 2004)
Cross-sectional analyses have associated vitamin A deficiency with genital shedding of herpes simplex virus (HSV) among human immunodeficiency virus type 1 (HIV-1)-infected women. A randomized clinical trial of vitamin A ...
