 AB    The addition of IFN-gamma to cultures of peripheral blood mononuclear
       cells (PBMCs) obtained from asymptomatic HIV-infected patients increased
       cell proliferation in response to HIV envelope synthetic peptides (Env),
       influenza A virus (VIRUS), and allogeneic lymphocytes (ALLO) but not to
       phytohaemagglutinin (PHA) stimulation. F(Ab)2 fragments of IgG purified
       from the sera of HIV-seropositive patients specifically interfered with
       IFN-gamma-induced cell proliferation in response to recall antigens.
       Neutralization of the lymphokine activity was found to be sustained by
       specific IFN-gamma antibodies. Data obtained demonstrate that IFN-gamma
       can restore the cell-mediated immunity of a number of asymptomatic HIV+
       individuals in vitro, while IFN-gamma antibodies present in sera of
       patients with AIDS interfere with the activity of the lymphokine.
