dc.description.abstract | We previously identified HIV-1 resistant prostitutes who remain persistently HIV-1 PCR- and
antibody-negative despite continued heavy exposure to HIV-1 through sex work. We hypothesized
that differences in virus-specific cytokine responses are associated with resistance vs. susceptibility
to infection. Although polyclonal activation failed to reveal such differences, antigen-mediated
activation of peripheral blood mononuclear cells (PBMC) in primary culture by using intact HIVIIIB
demonstrates that resistance is associated with enhanced virus-
d markedly
reduced IL-4 responses relative to those seen in HIV-1 seropositive prostitutes (CDC stage A1,
CD4>500/ml). No changes were detectable in HIV-stimulated interleukin (IL) 10 and IL-13
production, but IL-5 responses were somewhat increased in resistant sex workers. Moreover, the IL-
4 responses of HIV-1 resistant women to a panel of unrelated recall antigens were more than 20-fold
reduced relative to HIV-infected prostitutes or those of healthy Kenyan women not involved in sex
work. Thus, resistant women differ from seropositive-infected women and healthy controls by
exhibiting a profound global hyporesponsiveness in their capacity to generate IL-4 responses. | |
