Abstract

Rejection of tailskin grafts exchanged between two male hybrids of the cross B10.M × B10.RIII(71NS) revealed a mutation in the H-2f haplotype from the B10.M congenic line. Complementation studies with skin grafting and cell-mediated lympholysis showed the mutant, named H-2fb, to be different from another H-2f mutant, H-2fa, and further, that the H H-2fb mutation occurred in the D end of the H-2 complex. Reciprocal skin grafts exchanged between mutant and normal mice were rejected. Hemagglutinating antibody reactive with B10.M cells was raised in the mutant mice. Mutant spleen cells responded weakly, but significantly, to wild-type cells in a mixed lymphocyte culture and in a graftversus-host assay, but no response was seen in the opposite direction. However, cytotoxic effector cells were generated against target cells in both directions in a cell-mediated lympholysis assay.
