Identification and characterization of HLA-A*0301 epitopes in HIV-1 gag proteins using a novel approach
(2010-01)
Identification of CTL epitopes correlated to immune protection is important for the development of vaccines that enhance T-cell mediated immune responses. The correlation of positively selected amino acids (PS) of HIV-1 ...
The origins of a research community in the Majengo observational cohort study, Nairobi, Kenya
(2010-10-21)
Abstract
Background
Since the 1980s the Majengo Observational Cohort Study (MOCS) has examined sexually transmitted infections, in ...
CD26/ dipeptidyl peptidase IV (CD26/DPPIV) is highly expressed in peripheral blood of HIV-1 exposed uninfected Female sex workers
(2010-11-25)
Abstract
Background
Design of effective vaccines against the human immunodeficiency virus (HIV-1) continues to present formidable challenges. However, individuals who are exposed HIV-1 but do not get infected may reveal ...
Effect of Baseline HIV Disease Parameters on CD4+ T Cell Recovery After Antiretroviral Therapy Initiation in Kenyan Women
(2010)
Background
Antiretroviral therapy (ART) for HIV infection reconstitutes the immune system and improves survival. However, the rate and extent of CD4+ T cell recovery varies widely. We assessed the impact of several ...
HIV-Exposed seronegative commercial sex workers show a quiescent phenotype in the CD4+ T cell compartment and reduced expression of HIV-dependent host factors
(2010)
Studies of human immunodeficiency virus (HIV)–exposed seronegative individuals are crucial to informvaccine
design. In the present study we demonstrated that HIV-exposed seronegative commercial sex workers produce
lower ...
Evaluation of a quantitative real-time PCR assay to measure HIV-specific mucosal CD8+ T Cell responses in the cervix
(2010)
Several candidate HIV vaccines aim to induce virus-specific cellular immunity particularly in the genital tract, typically the
initial site of HIV acquisition. However, standardized and sensitive methods for evaluating ...
Evaluation of a quantitative real-time PCR assay to measure HIV-specific mucosal CD8+ T cell responses in the cervix
(Univerisyt of Nairobi, 2010-10)
Several candidate HIV vaccines aim to induce virus-specific cellular immunity particularly in the genital tract, typically the initial site of HIV acquisition. However, standardized and sensitive methods for evaluating ...
'Relief of oppression': An organizing principle for researchers' obligations to participants in observational studies in the developing world
(2010-06-30)
Abstract
Background
A central question in the debate about exploitation in international research is whether investigators and ...
Effects of a mobile phone short message service on antiretroviral treatment adherence in Kenya (WelTel Kenya1): a randomised trial
(2010)
Mobile (cell) phone communication has been suggested as a method to improve delivery of health services. However, data on the effects of mobile health technology on patient outcomes in resource-limited settings are limited. ...
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 ...
