Human Normal Peripheral Blood CD4+/CD25+/CD127low Regulatory T Cells (T reg)A subpopulation of CD4+ T cells constitutively expresses the IL 2 receptor alpha chain (CD25). These CD4+ CD25+ CD127lo T cells are regulatory T cells (Tregs), and in charge of regulating the activity of other T cells, usually by suppressing or down regulating the activity of effector T cells, to suppress the immune system to maintain homeostasis and tolerance to self antigens. So it is formerly known as suppressor T cells. Our Human Normal
