The role of G protein gene GNB3 C825T Polymorphism in HIV-1 acquisition, progression and immune activation
(2012)
Background
The GNB3 C825T polymorphism is associated with increased G protein-mediated signal transduction, SDF-1α-mediated lymphocyte chemotaxis, accelerated HIV-1 progression, and altered responses to antiretroviral ...
Reduced Cellular Susceptibility to In Vitro HIV Infection Is Associated with CD4+ T Cell Quiescence
(2012)
Background
HIV preferentially establishes productive infection in activated CD4+ T cells. Since proportions of activated CD4+ T cells vary between individuals, this study aimed to determine if individuals with a greater ...
Elevated expression of LAG-3, but not PD-1, is associated with impaired iNKT cytokine production during chronic HIV-1 infection and treatment
(University of Nairobi, 2015)
Background:
LAG-3 is a potent negative regulator of the immune response but its impact in HIV infection in
poorly understood. Unlike exhaustion markers such as PD-1, Tim-3, 2B4 and CD160, LAG-3 is poorly expressed on
bulk ...
Enrichment of LAG-3, but not PD-1, on Double Negative T Cells at the Female Genital Tract
(University of Nairobi, 2014-12)
Problem
The expression of inhibitory markers such as LAG-3 and PD-1 on T lymphocytes regulates immune function. Their expression at the genital mucosa is poorly understood, but regulation of immune activation at the ...
