The blockade of CD28 signalling is known to reduce pathological T cell responses in the context of both autoimmunity and transplantation, but has been associated with impairment of the regulatory T cell compartment. Here the authors show combining costimulation blockade with the administration of interleukin 2 selectively impairs the T effector response whilst maintaining the regulatory T cell pool and suggest functional effect in a murine model of autoimmune diabetes.
