Outline of Final Research Achievements

Immune tolerance is maintained in the healthy condition; however, autoimmune diseases occur once immune tolerance is broken. We found that loss of a genome organiser, Special AT-rich binding protein-1 (SATB1), leads to autoimmune diseases in mice. In SATB1 deficient mice, negative selection, in which auto-reactive T cells are eliminated, is impaired. Therefore, SATB1 plays a critical role in establishment of immune tolerance.
