摘要：Culture conditions suitable for specific sensitization of human peripheral blood lymphocytes were established. Production of antibody to sheep erythrocytes and to the 2,4,6-trinitrophenyl group conjugated to burro erythrocytes was investigated in terms of cross-sensitization, feedback control by antibody to the immunogen, and regulation by helper and suppressor T cells. Generation of antigen-specific antibody-forming cells was found to be restricted to a narrow concentration range of cultured peripheral blood lymphocytes. The data suggest that antibody formation is limited by suppressor T cells in high-cell-density cultures and by low frequencies of helper T cells in low-cell-density cultures.
