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 ...
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 ...
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 ...
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 ...
Controlling HIV in Africa: effectiveness and cost of an intervention in a high-frequency STD transmitter core group.
(1991)
Since 1985, a population of over 1,000 predominantly HIV-positive female prostitutes residing in a low-income area of Nairobi, has been enrolled in a sexually transmitted disease (STD)/HIV control programme. The major ...
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, ...
Genetic diversity and mosaicism at the por locus of Neisseria gonorrhoeae.
(1999)
The por genes of the predominant serovars of Neisseria gonorrhoeae circulating in a high-frequency transmitter core group located in Nairobi, Kenya, were examined for nucleotide sequence polymorphism. The level of por gene ...
Leukocyte esterase urine strips for the screening of men with urethritis--use in developing countries
(1994)
The leukocyte esterase (LE) strip is a useful tool for the screening of men with urethritis. In developing countries, where laboratory facilities are limited, and sexually transmitted diseases endemic, simple and inexpensive ...
