abstractsThe occurance and development of autoimmune thyroid disease (AITD)is related with changes of quantities and function of CD4~+CD25~+ regulatory T(Treg) cells. Different studies indicated that Treg cells can inhibit the development of AITD. Depletion of Treg cells can improve the incidence of AITD or increase the severity of AITD. Treg cells play roles in inhibiting activation of effector T cell. No matter Treg cells or CD4~+ CD25~+ regulatory T cells generated in the periphery can influence the development of AITD.
