Coinfection with herpes simplex virus type 2 is associated with reduced HIV-specific T cell responses and systemic immune activation.
(University of Nairobi,, 2008)
BACKGROUND:
Chronic coinfection with herpes simplex virus type 2 (HSV-2) and human immunodeficiency virus (HIV) has been associated with an increased HIV viral load and more rapid disease progression, perhaps related to ...
Relative HIV Resistance In Kenyan Sex Workers Is Not Due To An Altered Prevalence Or Mucosal Immune Impact Of Herpes Simplex Virus Type 2 Infection.
(University of Nairobi, 2009-09)
Chronic infection by herpes simplex virus type 2 (HSV-2) increases HIV susceptibility, perhaps due to HSV-2-associated increases in activated mucosal immune cells. A small number of Kenyan female sex workers (FSWs) exhibit ...
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 ...
Recombination following superinfection by HIV-1.
(University of nairobi, 2004)
Background: There is increasing recognition of recombinant HIV-1 strains globally, but it has been unclear whether recombination results from superinfection during untreated, chronic infection.
Objective: To search for ...
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, ...
Mucosal Neisseria gonorrhoeae coinfection during HIV acquisition is associated with enhanced systemic HIV-specific CD8 T-cell responses
(2008)
Background: The host immune response against mucosally acquired pathogens may be
influenced by the mucosal immune milieu during acquisition. As Neisseria gonorrhoeae
can impair dendritic cell and T-cell immune function, ...
Reduced rates of HIV acquisition during unprotected sex by Kenyan female sex wo kers predating population declines in H IV prevalence
(2008)
OBJECTIVES:
Female sex workers (FSWs) form a core group at high risk of both sexual HIV acquisition and secondary transmission. The magnitude of these risks may vary by sexual risk taking, partner HIV prevalence, host ...
HIV-neutralizing immunoglobulin A and HIV-specific proliferation are independently associated with reduced HIV acquisition in Kenyan sex workers.
(University of Nairobi,, 2008-03)
OBJECTIVES:
HIV-neutralizing immunoglobulin A (IgA) and HIV-specific cellular immunity have been described in highly exposed, persistently seronegative (HEPS) individuals, but well controlled studies have not been performed. ...
HIV-1-specific mucosal CD8+ lymphocyte responses in the cervix of HIV-1-resistant prostitutes in Nairobi
(, 2000)
Understanding how individuals with a high degree of HIV exposure avoid persistent infection is paramount to HIV vaccine design. Evidence suggests that mucosal immunity, particularly virus-specific CTL, could be critically ...
Plasma and mucosal fluid from HIV type 1-infected patients but not from HIV type 1-exposed uninfected subjects prevent HIV type 1-exposed DC from infecting other target cells.
(University of Nairobi, 2007-01-23)
Highly exposed persistently seronegative (HEPS) individuals have previously been shown to mount HIV-1-specific humoral and cellular immune responses in the mucosa, despite their uninfected status. It is thus possible that ...
