Abstract

Genes located in the I region of the H-2 complex control a system of lymphocyte alloantigens (Ia) which are expressed on subpopulations of T and B cells. Specific anti-Ia serum plus rabbit complement removed the B-lymphocyte population responsive to the mitogen LPS and the subpopulation of T cells responsive to Con-A. Lymphocytes sensitive to PHA or leucoagglutinin were not removed by anti-Ia serum and complement. Significant inhibition of the proliferative response to LPS was also obtained by brief periods of cell pretreatment with anti-Ia antibodies without complement. This inhibition was specific with the appropriate anti-Ia serum and did not occur with anti-H-2K sera or when cells of a different I region were pretreated.
