The results in this report indicate that the OKT3 monoclonal antibody, which is specific for a human T cell differentiation antigen present on 90 to 95% of peripheral T cells, can exert several effects that regulate the generation and expression of human influenza virus-immune cytotoxic T lymphocytes (CTL). The OKT3 antibody, but not OKT1 or OKT11 (which bind to all peripheral T cells), is able to inhibit anti-influenza CTL effector cell activity. An F(ab')2 preparation of OKT3 IgG were as effective as whole IgG for the inhibition of CTL effectors, indicating that the inhibitory activity of the antibody was not a function of the Fc portion of the molecule. OKT3 IgG and OKT3 F(ab')2 fragments (but not OKT4, OKT8, or OKI were able to inhibit the generation of anti-influenza CTL. The culture of human lymphoid cells with OKT3 in the presence or absence of influenza virus induced radioresistant cells that could suppress the CTL response of fresh autologous lymphocytes to influenza. These results suggest that T cell functions can be regulated by signals that are initiated by the binding of antibody to cell surface molecules that may not be related to the T cell antigen-specific receptor(s).
