Distinct kinetics of Gag-specific CD4+ and CD8+ T cell responses during acute HIV-1 infection.
HIV infection is characterized by a gradual deterioration of immune function, mainly in the CD4 compartment. To better understand the dynamics of HIV-specific T cells, we analyzed the kinetics and polyfunctional profiles of Gag-specific CD4(+) and CD8(+) T cell responses in 12 subtype C-infected individuals with different disease-progression profiles, ranging from acute to chronic HIV infection...
متن کاملHIV-1-specific cellular immune responses among HIV-1-resistant sex workers.
The goal of the present study was to determine whether there were HIV-1 specific cellular immune responses among a subgroup of women within a cohort of Nairobi prostitutes (n = 1800) who, despite their intense sexual exposure to HIV-1, are epidemiologically resistant to HIV-1 infection. Of the 80 women defined to be resistant, 24 were recruited for immunological evaluation. The HIV-1-specific T...
متن کاملDecay Kinetics of HIV-1 Specific T Cell Responses in Vertically HIV-1 Exposed Seronegative Infants
OBJECTIVE The majority of infants born, in developed countries, to HIV-1 positive women are exposed to the HIV-1 virus in utero or peri/post-partum, but are born uninfected. We, and others, have previously shown HIV-1 specific T cell responses in HIV-1 exposed seronegative (HESN) neonates/infants. Our objective in this study was to examine the rate of decay in their HIV-1 specific T cell respon...

متن کاملHIV-1-specific CTLs effectively suppress replication of HIV-1 in HIV-1-infected macrophages.
Both CD4+ T cells and macrophages are major reservoirs of HIV-1. Previous study showed that HIV-1-specific cytolytic T lymphocytes (CTLs) hardly recognize HIV-1-infected CD4+ T cells because of Nef-mediated HLA class I down-regulation, suggesting that HIV-1 escapes from HIV-1-specific CTLs and continues to replicate in HIV-1-infected donors. On the other hand, the CTL recognition of HIV-1-infec...
