N2 - In the present experiments we have explored the possibilities of a modified immunoadsorbent technique to select for (1) mutagenized T cell receptor (Tcr) negative variants of Jurkat T lymphoma cells and (2) purified CD-4+ or CD-8+ T lymphocytes. The basic principle was to make large numbers of immunoglobulin (Ig) negative T cells Ig+ by T cell subset-specific monoclonal antibodies (mAb), and to select such cells on Ig anti-Ig columns. Our results demonstrated that Thy-1+, Fc receptor positive, antigen-specific T cells regulate the immune response in mice nonresponders to pork insulin, and the "autologous" mixed lymphocyte reaction. In addition, the immunoadsorbent method very efficiently selects Tcr/CD-3- variants from mutagenized Jurkat cell populations incubated with anti-CD3 mAb. The described method is easy and quick and can fractionate large numbers of cells; it is the "poor-man's cell sorter." The most important finding is the demonstration of antigen-specific Thy-1+, CD-8+, and Fc receptor+ T suppressor cell that apparently react with antigen in a non-major histocompatibility complex-restricted manner.
