Web2. Antigen specificity of thymus-derived Treg cells A large body of indirect evidence suggests that thymus-derived Treg (tTreg) cells recognize autologus antigens. However, the major self-antigens recognized by Treg cells have remained largely undefined, representing a major barrier to the understanding of immune regulation.
