Functional HIV-1 specific IgA antibodies in HIV-1 exposed, persistently IgG seronegative female sex workers
(2001-11)
Although HIV-specific cellular immune responses are found in a number of HIV highly-exposed, persistently seronegative (HEPS) cohorts, late seroconversion can occur despite pre-existing cytotoxic T lymphocytes (CTL), ...
Prevalence and risk factors of three curable sexually transmitted infections among women in Nairobi, Kenya
(http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4812604/, 2016-03)
Background
Sexually transmitted infections (STIs) are a major public health problem, especially in developing countries. The complications of untreated STIs in the female genital tract and their role in adverse pregnancy ...
Prevention of mother-to-child transmission of HIV in Kenya: challenges to implementation
(University of Nairobi, 2014)
Background:
The prevention of mother-to-child transmission of human immunodeficiency virus (HIV) is lauded as
one of the more successful HIV prevention measures. However, despite some gains in the prevention of ...
Prevention of mother-to-child transmission of HIV in Kenya: challenges to implementation
(University of Nairobi,, 2014)
Background
The prevention of mother-to-child transmission of human immunodeficiency virus (HIV) is lauded as one of the more successful HIV prevention measures. However, despite some gains in the prevention of mother-to-child ...
Reduced HIV-1 long terminal repeat transcription in subjects with protective interferon regulatory factor-1 genotype: A potential mechanism mediating resistance to infection by HIV-1
(2010)
We previously described the polymorphism in the interferon regulatory factor-1 (IRF-1) gene as a novel correlate of resistance to HIV-1 infection in a Kenyan female sex worker cohort. However, the underlying mechanisms ...
A Trim5alpha Exon 2 Polymorphism is Associated with Protection from HIV-1 Infection in Pumwani Sexworker Cohort
(2010)
Objective
The innate immune component TRIM5α has the ability to restrict retrovirus infection in a species-specific manner. TRIM5α of some primate species restricts infection by HIV-1, while huTRIM5α lacks this specificity. ...
Presence of CD8+ T Cells in the Ectocervical Mucosa Correlates with Genital Viral Shedding in HIV-Infected Women despite a Low Prevalence of HIV RNA–Expressing Cells in the Tissue
(2014)
The female genital tract is a portal of entry for sexual HIV transmission and a possible viral reservoir. In this study, the ectocervical CD8+ T cell distribution was explored in situ and was related to expression of CD3 ...
High Prevalence of Genetically Similar HIV-1 Recombinants among Infected Sex Workers in Nairobi, Kenya
(University of Nairobi, 2008)
HIV-1, a highly diverse infectious agent, shows the greatest sequence diversity in highly exposed individuals, including greater levels of recombination. HIV-1 diversity in Nairobi, Kenya was examined in 240 individuals, ...
Low expression of activation and inhibitory molecules on NK cells and CD4+ T cells Is associated with viral control
(University of Nairobi, 2015)
Chronic HIV-1 infection induces severe immune alterations, including hyperactivation, exhaustion, and apoptosis. In fact, viral control has been associated with low frequencies of these processes. Here, we evaluated the ...
