WebThe conclusions are then tested by reinterpreting a published probing set of data purporting to show that Treg cells regulate tolerance. It is concluded that the major role of suppression is to operate as a feedback mechanism modulating the magnitude of the effector response; it is not a determinant of the S-NS discrimination (i.e. tolerance).
