title: The genetic control of T cell-mediated immunity against the DBA/2 mastocytoma P-815. II. Low responsiveness in T cell-mediated cytotoxicity accompanied by the inability to produce antibodies in a secondary response.
abstract: Low responsiveness of DBA/1 mice in T cell-mediated cytotoxicity against the DBA/2 mastocytoma P-815 (H-2d) is genetically controlled and inherited as a recessive trait. For an analysis of the humoral anti-H-2d response of DBA/1 mice after immunization with P-815 mastocytoma cells both complement-dependent lysis (CDL) and the cytotoxicity inhibition assay (CIA) were used to demonstrate antibodies. Both assays show that DBA/1 mice are unable to produce anti-H-2d antibodies in a secondary response. Even high doses of immunizing cells give only a weak response. The response is fully recovered upon allogeneic interaction. A transient primary anti-H-2d activity can be found in the CIA but not by CDL. The data show that the genetically controlled determinant-specific defect in T cell-mediated cytotoxicity among DBA/1 mice has its correlate in a blockade of memory formation or expression in the humoral anti-H-2d response.
