Suppression of autoimmunity in nzb mice with steroid‐sensitive x‐radiation‐sensitive syngeneic young thymocytes

Abstract
NZB mice spontaneously lose thymic regulatory or suppressor cells and subsequently develop autoimmunity and lymphoreticular hyperlasia. Treatment with 2‐week‐old syngeneic thymocytes every 2 weeks starting at 4 weeks of age suppressed these disease manifestations. The active thymocyte subpopulation was found to be sensitive to corticosteroids and X‐irradiation.
