Overview

abstract

  • A comparison of the proliferative responses of lymphocytes to human immunodeficiency virus (HIV) antigens from long-term, seronegative heterosexual partners of HIV-infected subjects, from normal unexposed controls and from healthy seropositive heterosexual partners or seropositive, asymptomatic men, reveals that lymphocytes from healthy seropositive individuals with strong proliferative responses to recall, microbial antigens respond only minimally to HIV proteins or envelope peptides, and that even these low responses do not occur in all individuals. If the frequency of responses to several HIV antigens are analyzed, lymphocytes from both HIV-exposed seropositive and seronegative partners of infected individuals proliferate to HIV antigens to a greater degree than lymphocytes from unexposed, normal control individuals. Although lymphocytes from seropositive partners proliferate to a greater degree than those from seronegative partners, the latter are more similar to seropositive partners than they are to normal controls. This observation suggests that these seronegative partners may have become sensitized to HIV antigens through sexual exposure but without infection, and/or that the presence or development of these small immune responses in some individuals might be associated with a failure to become infected.
