Monoclonal antibodies reactive with defined T lymphocyte surface antigens were covalently coupled to protein A-Sepharose beads using the bifunctional imidoester, dimethyl pimelimidate. Sepharose-immobilized antibody reactive with T3 induced the proliferation of resting T lymphocytes in the presence of either recombinant interleukin 2 or phorbol myristate acetate. When monoclonal antibodies reactive with T3 and T4 were coupled to the same Sepharose bead (hereafter designated Sepharose (T3:T4)), proliferation was enhanced an average of three-fold. Similarly prepared Sepharose beads coupled to anti-T3 and anti-T8 also enhanced proliferation over that observed with anti-T3 alone. Sepharose (T3:T4) similarly increased the proliferation of T4+ lymphocytes and a T4+ clone but failed to enhance the proliferation of T8+ lymphocytes. The increased proliferation of T4+ lymphocytes resulted from a preferential activation of the T4+2H4- helper population over the T4+2H4+ suppressor-inducer population. The enhanced proliferation induced by Sepharose (T3:T4) could be completely inhibited by soluble anti-T4. These results suggest that perturbation of T3 may be a minimal signal for T cell activation and that the assembly of a multimeric complex including T3 and T4 may be required for optimal T cell activation.
