Outline of Final Research Achievements |
In order to identify the candidate molecules for the development of the effector cell-targeted treatment for the inhibition of type 1 diabetes, we have developed IL-17/IFN-gamma receptor-double-deficient, Granzyme B-deficient, IRF4-deficient NOD mice. IL-17/IFN-gamma R double-deficiency significantly suppressed the development of diabetes, while independent deletion of IL-17 or IFN-gammaR did not alter the disease susceptibility in NOD mice. Granzyme B-deficient NOD mice spontaneously developed diabetes with similar kinetics to wild-type NOD mice. Diabetes/insulitis and autoantibody production were completely suppressed in IRF4-deficient heterozygous as well as homozygous NOD mice. These suggest that the an IRF4-targeted strategy may be useful for modulating autoimmunity in type 1 diabetes.
