[IgM and IgG rosette formation in the primary and secondary immune response in the system of syngeneic transfer of spleen cells].

In the system of syngenous transfer of cells a study was made of the dynamics of IgM- and IgG- of the rosette-froming cells of the spleen in the primary and secondary immune response in mice of the CBA inbred strain immunized with sheep erythrocytes. It was shown that in prolongation of the interval between donor immunization and the transfer of cells to the recipient with his simultaneous immunization for up to 40 days there occurred an increase of the IgG-memory; as to IgM memory-it is expressed with shorter intervals. It is supposed that rosette-forming cells were not bearers of immunological memory.
