Deficient CD4+ CD25+ FOXP3+ T regulatory cells in acquired aplastic anemia

Abstract excerpt

Regulatory T cells are believed to control the development and progression of autoimmunity by suppressing autoreactive T cells. Decreased numbers of CD4(+)CD25(+) FOXP3(+) T cells (Tregs) are associated with impaired immune homeostasis and development of autoimmune diseases. The transcription factors FOXP3 and NFAT1 have key roles in regulatory T-cell development and function. We show that Tregs are decreased at...
