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 ...
Cross-reactive cytotoxic T lymphocytes against a HIV-1 p24 epitope in slow progressors with B*57.
(2007-05)
OBJECTIVES:
To determine whether CD8 T lymphocytes from HIV-1-infected patients expressing B*5701 and B*5703 show broad cross-reactivity against different variants of a conserved p24 epitope, which might account for the ...
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 ...
Elevated elafin/trappin-2 in the female genital tract is associated with protection against HIV acquisition
(2009)
Globally, heterosexual intercourse is the primary route of HIV-1 (HIV) transmission. It follows that mechanisms that protect against HIV infection are likely operative at the genital mucosa. In HIV-resistant Kenyan sex ...
Sequence and peptide-binding motif for a variant of HLA-A*0214 (A*02142) in an HIV-1-resistant individual from the Nairobi Sex Worker cohort
(Springer-Verlag, 2001)
As part of the ongoing study of natural HIV-1 resistance in the women of the Nairobi Sex Workers' study, we have examined a resistance-associated HLA class I allele at the molecular level. Typing by polymerase chain reaction ...
Effect of human immunodeficiency virus (HIV) type 1 viral genotype on mother-to-child transmission of HIV-1.
(2000)
The objective of this study was to determine whether the maternal infecting human immunodeficiency virus (HIV) type 1 clade affects mother-to-child transmission frequency. Mothers in the mother-to-child HIV-1 transmission ...
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, ...
Characterization Of Protein-protein Interactions Between The Nucleocapsid Protein And Membrane Protein Of The Sars Coronavirus.
(University of Nairobi, 2004-10)
The human coronavirus, associated with severe acute respiratory syndrome (SARS-CoV), was identified and molecularly characterized in 2003. Sequence analysis of the virus indicates that there is only 20% amino acid (aa) ...
