Genetic determination of the immune response in mice to cells of different histological type.

The intensity of the cellular immune response to strong transplantation antigens of the H-2 complex is related to the histological type of cells taken for immunization. Splenic cells from C3H mice immunized BALB/c mice better than cells of non-lymphoid origin from the same donor. The reverse was observed when, instead of BALB/c mice, C57B1/6 and A/He were used in immunization experiments. Analysis of the inheritance of this immunization pattern studied in mice of the first generation from various crosses between strains (BALB/c, C57B1/6 and A/He) and in mice from backcrosses has demonstrated that this immunization pattern is not inherited as a simple Mendelian character. Therefore, it could be supposed that efficiency of immunological control of cells having different histological types, may be genetically determined. [ABSTRACT FROM AUTHOR]
