Regulation of mucosal and systemic immune activation during the menstrual cycle of female sex workers from nairobi, kenya; local regulation and HIV-induced impairment
(University of Nairobi, 2015)
Problem:
Vaginal intercourse is the main route of HIV infection among women. To result in a productive infection, HIV must encounter activated targets that sustain replication. Sexual hormones modulate activation and ...
Increased levels of inflammatory cytokines in the female reproductive tract are associated with altered expression of proteases, mucosal barrier proteins, and an influx of HIV-susceptible target cells.
(University of Nairobi, 2015)
Elevated inflammatory cytokines (EMCs) at mucosal surfaces have been associated with HIV susceptibility, but the underlying mechanisms remain unclear. We characterized the soluble mucosal proteome associated with elevated ...
Murine Plasmodium chabaudi malaria increases mucosal immune activation and the expression of putative HIV susceptibility markers in the gut and genital mucosa.
(University of Nairobi, 2013-11)
To evaluate if systemic murine malarial infection enhances HIV susceptibility through parasite-induced mucosal immune alterations at sites of HIV sexual exposure.
BACKGROUND::
Malaria and HIV have a high degree of ...
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 ...
Hiv-specific Cd8+ T-cell Proliferation Is Prospectively Associated With Delayed Disease Progression.
(University of Nairobi, 2012-03)
Human immunodeficiency virus (HIV)-specific CD8(+) T-cell proliferation is consistently correlated with enhanced host HIV immune control, but whether proliferative responses are a cause or consequence of immune protection ...
Mucosal Serpin A1 And A3 Levels In Hiv Highly Exposed Sero-negative Women Are Affected By The Menstrual Cycle And Hormonal Contraceptives But Are Independent Of Epidemiological Confounders.
(University of Nairobi, 2013-01)
OBJECTIVE:
Serpins (serine protease inhibitors) are associated with protection against HIV infection. Here, we characterized mucosal serpin expression in the genital tract of HIV highly exposed sero-negative (HESN) women ...
Characterization of an HLA-C-restricted CTL response in chronic HIV infection
(University of Nairobi,, 2010-04)
HIV-specific CTL play an important role in the host control of HIV infection. HIV-nef may facilitate escape of HIV-infected cells from CTL recognition by selectively downregulating the expression of HLA-A and HLA-B molecules, ...
Association of high-risk sexual behaviour with diversity of the vaginal microbiota and abundance of Lactobacillus.
(University of Nairobi, 2017)
OBJECTIVE:
To compare the vaginal microbiota of women engaged in high-risk sexual behaviour (sex work) with women who are not engaged in high-risk sexual behaviour. Diverse vaginal microbiota, low in Lactobacillus species, ...
Impact of Standard Bacterial Vaginosis Treatment on the Genital Microbiota, Immune Milieu, and Ex Vivo Human Immunodeficiency Virus Susceptibility.
(Oxford Academic, 2018-09-12)
BACKGROUND:
Genital immunology is a key determinant of human immunodeficiency virus (HIV) susceptibility. Both factors are modulated by bacterial vaginosis (BV) and, to some extent, by Lactobacillus iners, the genital ...
Association between vaginal washing and vaginal bacterial concentrations.
(PLoS, 2019-01-24)
Vaginal washing is a common practice associated with adverse outcomes including bacterial vaginosis (BV) and HIV infection. Prior studies have not examined the associations between vaginal washing and individual vaginal ...
