[Animal models for autoimmune thyroid disease].

Animal models for chronic thyroiditis include (1) experimental autoimmune thyroiditis induced by immunizing rabbits or rodents with thyroid extracts or thyroglobulin and (2) spontaneous thyroiditis in certain species of rodents and chickens. For Graves' disease, no spontaneous animal models are reported. An animal model for Graves' disease has been developed by xenotransplantation of Graves' thyroid tissue plus autologous immune cells to immunodeficient mice. Another animal model for Graves' disease is made by immunizing TSH receptor-peptide or protein to mice. Animal models are very useful for studying etiology of autoimmune thyroid diseases, although no current animal models are satisfactory for human autoimmune thyroid disease.
