| Research Abstract |
IkB-family protein, IkB-zeta located into nuclear, and control NF-kB target gene expression. IkB-zeta deficient (KO) mice caused autoimmune like sjogren's syndrome with age.
Thus, we hypothesis that KO mice have problem about the suppressor ability, stability or generation of regulatory T cells (Treg).
We found that regulatory T cells (Tregs) from KO mice has less suppression ability compared with control mice. We also found that stability of Tregs were comparable between control and KO mice. In addition, IkB-zeta plays an pivotal role for Tregs fate desition.
