Regulatory T cells (Treg) are functionally mature T cell subpopulations which are key players of maintaining the balance of immunological defense system. Treg can proliferate in vivo or in vitro by antigen specific way or non-antigen specific way, and actively control the properties of other immune cells by suppressing their functional activity and their proliferation as well.
