The present disclosure relates to genetically modified non-obese diabetic (NOD) mice deficient in murine class I MHC molecules, class II molecules, or both class I and class II MHC molecules. The MHC knockout transgenic mice provided herein are useful, for example, for developing therapies for diabetes.

Murine-MHC-deficient HLA-transgenic nod-mouse models for T1D therapy development

Provided are oligopeptide antigens to AI4-like T cells, and mouse proteins comprising those antigens. The oligopeptide antigens comprise the amino acid sequence XX(I/D/F/L)ENY(I/L)(E/W/Y)(L/M) or VMLENYTHL. Additionally provided are methods for treating a mammal having or at risk for type 1 diabetes using these antigens, or compounds which reduce or eliminate expression of these antigens. Kits comprising these antigens, and methods for determining whether a mammal is at risk for or has type 1 diabetes are also provided.
