Recent data have suggested that non-obese diabetic (NOD) mice display a defect in negative thymic selection. Using mixed bone marrow chimeras, we demonstrate that the NOD allele of the diabetes susceptibility region 5 (Idd5) locus on chromosome 1, confers defective negative selection in response to endogenous superantigens (SAg) Mtv8 and Mtv9. We generated mixed bone marrow (BM) chimeras in which the donor cells of NOD and C3H or NOD.Idd5(b10) and C3H coexist and are similarly exposed to the Mtv8 and Mtv9 SAg. Under these conditions, SAg-mediated deletion of Vbeta11+ T cells is less efficient in chimeric mice reconstituted with NOD+C3H BM, compared with chimeras reconstituted with NOD.Idd5(b10)+C3H BM. Interestingly, the observed discrepancy was not T cell autonomous but was found to be mediated by a BM derived cellular subset, and under control of a gene(s) in the Idd5 region.
