| Outline of Final Research Achievements |
The purpose of this study was to identify genes responsible for both autoimmuninty and organ-specificity of type 1 diabetes. Type 1 diabetes and autoimmune thyroid diseases (AITD), alopecia areata and AITD, are often develop in the same individuals, whereas type 1 diabetes and AA are very rare to be observed in the same individuals. HLA-DR4 haplotype (DRB1*04:05-DQB1*04:01) was found to be responsible for beta-cell specificity in autoimmune diseases. targeted disruption of MafA in NOD mice resulted in protection, but not accerelation, of beta-cell autoimmunity and type 1 diabetes. Accumulation of regulatory T-cells in insulitis legion was suggested to be possible mechanism of protection from beta-cell autoimmunity and type 1 diabetes.
