do they really help us to understand human autoimmunity?
Organ-specific or endocrine autoimmune diseases are complex, polygenic afflictions the penetrance of which is heavily dependent on various environmental influences. Important target tissues are the thyroid, the islets of Langerhans, gastric parietal cells and steroid-producing cells in the adrenal and ovary. The etiology of these diseases remains to be clarified. The pathogenesis is strongly associated with autoimmune phenomena. None of the current treatment approaches provides a cure; rather they represent replacement therapy. An important objective in the treatment of endocrine/organ-specific autoimmune diseases is the detection of individuals at risk for the development of such diseases and the development of interventions to prevent an outbreak of the diseases. This requires an exquisite knowledge of the early etio-pathogenic stages of these diseases. This review concentrates on the usefulness of animal models for a precise understanding of these very early stages. It must be empha
