CD4(+)CD25(+) regulatory T cells are thought to be a subgroup of cells which have the function of immune suppression. 5 to 10 percentage of peripheral CD4(+) T cells and 1% - 2% of peripheral mononuclear cells are CD4(+)CD25(+) regulatory T cells in mouse or healthy human. They can suppress immune response through many pathways and sustain the stabilization of internal environment. Idiopathic thrombocytopenic purpura is a kind of autoimmunity disease which mainly has a manifestation of hemorrhage in some locations such as skin, mucosa or viscera. Recent findings support that CD4(+)CD25(+) regulatory T cells are relevant to the morbidity of idiopathic thrombocytopenic purpura. In this review, the recent advance on characteristics and function of CD4(+)CD25(+) regulatory T cells, pathogenesis of idiopathic thromocytopenic purpura and role CD4(+)CD25(+) regulatory T cells in pathogenesis of idiopathic thrombocytopenic purpura were summarized.
