A Comparison Of Parallel Pyrosequencing And Sanger Clone-based Sequencing And Its Impact On The Characterization Of The Genetic Diversity Of Hiv-1.
(University of Nairobi, 2011)
BACKGROUND:
Pyrosequencing technology has the potential to rapidly sequence HIV-1 viral quasispecies without requiring the traditional approach of cloning. In this study, we investigated the utility of ultra-deep ...
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 ...
Novel Interferon Regulatory Factor-1 Polymorphisms In A Kenyan Population Revealed By Complete Gene Sequencing
(University of Nairobi, 2004)
Variation in susceptibility to HIV-1 infection depends on numerous factors, and host genetic variation has been well-described as an important component. As a transcriptional regulator, interferon regulatory factor 1 (IRF-1) ...
Elevation Of Immune Activation In Kenyan Women Is Associated With Alterations In Immune Function: Implications For Vaccine Development.
(University of Nairobi, 2004-11)
The infectious burden leading to immune activation can vary between different populations and lead to various immune dysfunctions. We compared the effect of immune activation on apoptosis and T cell function in HIV uninfected ...
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 ...
Association of sex work with reduced activation of the mucosal immune system
(University of Nairobi, 2014-01)
Background. Unprotected intercourse and seminal discharge are powerful activators of the mucosal immune system and are an important risk factors for HIV transmission. This study was designed to determine if female sex work ...
Construction of an infectious HIV type 1 molecular clone from an African patient with a subtype D/C Recombinant Virus.
(2004)
The majority of HIV-1 infections worldwide occur in Africa, where subtype B viruses are rare and intersubtype recombinants are common. Pathogenesis and vaccine studies need to focus on viruses derived from African patients, ...
Anti-HIV-1 activity of elafin depends on its nuclear localization and altered innate immune activation in female genital epithelial cells.
(University of Nairobi, 2012-12-27)
Elafin (E) and its precursor trappin-2 (Tr) are alarm antiproteases with antimicrobial and immunomodulatory activities. Tr and E (Tr/E) have been associated with HIV-1 resistance. We recently showed that Tr/E reduced IL-8 ...
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, ...
