Induction of FoxP3+CD4+CD25+ regulatory T cells by a bone marrow population distinct from plasmacytoid-DC.

abstract：:Bcl-2 proto-oncogene is expressed in normal lymphoid tissues and its role has been suggested to involve the selection of B and T cells. Here we report three-color flow cytometric studies on the expression of bcl-2 protein in the thymus and periphery. Bcl-2 was expressed in the majority of T and B cells and down-regula...
