Rosette formation and humoral immune response to 2,4-dinitrophenol in mice of different inbred strains]

A study was made of the content of rosette-forming cells to DNP-ovalbumin in the spleen of mice of different inbred strains. The values of the rosette-forming cells and of the titre of serum agglutinins to the DNP-group in DNP--bovine gamma-globulin immunization of mice of these strains were determined. It was shown that there were interstrain differences in respect to the normal and immune rosette-forming cells and also humoral antibodies. There was noted a direct correlation between the number of the immune rosette-forming cells and the antibody titre in the serum of mice of the same inbred strain. Immune response (both by the content of rosettes in the spleen and by the antibody level) proved to be the minimal in mice with the highest level of rosette-forming cells. There proved to be no inverse relationship.
