INDUCTION OF ALLOGRAFT TOLERANCE AFTER TOTAL LYMPHOID IRRADIATION (TLI) - DEVELOPMENT OF SUPPRESSOR CELLS OF THE MIXED LEUKOCYTE REACTION (MLR) JOURNAL OF IMMUNOLOGY Slavin, S., Strober, S. 1979; 123 (2): 942-946

Abstract

We searched for the presence of suppressor cells of the MLR in C57BL/Ka leads to BALB/c chimeras. The chimeras were made with total lymphoid irradiation (TLI) and marrow transplantation. Spleen cells from the old chimeras inhibited the MLR of BALB/c responder cells against C57BL/Ka stimulator cells. Inhibition was specific for the stimulator cells, since no effect on the MLR was observed with C3H or BALB.C3H stimulator cells. Maximal inhibition was achieved when the responder cells in the MLR shared the H-2 haplotype of the chimeric recipient. Spleen cells obtained from chimeras young 30 to 40 days after BM transplantation inhibited the MLR nonspecifically, since similar marked inhibition was observed regardless of the H-2 haplotype of the responder or stimulator cells. The finding of antigen-specific and nonspecific suppressor cells is similar to that observed in mice rendered tolerant to bovine serum albumin after treatment with TLI.
