    Abstract:
    A mixture of lymph node cells from CBA mice and spleen cells from C57Bl/6J mice stimulated by the cheep erythrocytes fro the first or second time was transplanted in the lethally irradiated mice (CBA X C57Bl/6j)Fl. The interaction of allogenic cells during the secondary immune response was accompanied by the complete inactivation of antibody producents. Under the ratio of interacting cell elements 1 : 1-1 : 2, 93-96% of precursor cells and 98% of antibody forming cells were inactivated. Under the ratio 1 : 5, the index of inactivation of precursor cells fell down to 35%. During the primary response, under the ratio 1 : 1, only 20-48% of precursor cells and 68% of antibody forming cells were inactivated. Under the ratio 1 : 2, no inactivation of precursor cells was observed and, under the ratio 1 : 10, the antibody formation was stimulated. Following the delayed by 1-3 days transplantation of CBA lymphocytes, the cooperative effect was registered with respect to the spleen cells from C57Bl/6J mice stimulated by the erythrocytes for the first time. The interaction of allogenic cells resulted in the 3-4-fold increase in the number of antibody forming cells.
