| abstractText | To localize and characterize the MHC-linked diabetogenic gene of the NOD mouse, we studied the class III region of the MHC in the NOD mouse and related strains. Hsp70, Bat5, Tnfa and Tnfb loci were studied by microsatellite polymorphism analysis and/or restriction mapping. The CTS mouse had the same allele as the NOD mouse at the Hsp70 locus, but different alleles at the Bat5, Tnfa and Tnfb loci from those of the NOD mouse. Our previous studies indicated that in the CTS mouse, class II MHC was the same as that of the NOD mouse, but that class I MHC was different at both K and D loci, and that CTS MHC was diabetogenic in the presence of NOD background genes. These data map major genetic susceptibility to type 1 diabetes to the segment flanked by class I K and class III Bat5 loci. Moreover, since the diabetogenic effect of the CTS MHC is weaker than that of the NOD MHC, these data suggest the presence of a second MHC-linked gene or gene complexes that modulate susceptibility to type 1 diabetes outside this segment. |
