Models to study the pathogenesis of thyroid autoimmunity.
In vitro and in vivo models to study the pathogenesis of thyroid autoimmunity are reviewed. Animal models with experimentally induced or spontaneously developed autoimmune thyroid disease as well as transplantation models have been used extensively in these studies, but also the use of thyroid cell cultures from both humans and animals has contributed to the present state of knowledge. Cytokines may play a role in the pathogenic mechanism in thyroid autoimmunity. The major in vitro and in vivo effects of for example interleukin-1, tumour necrosis factor and gamma-interferon on differentiated thyroid cell functions are inhibitory. The advantage of using cell cultures has been the possibility of studying an influence on thyrocytes from a single agent individually, such as cytokines, hormones or growth factors. The disadvantage is that an organism is under the influence of a multitude of factors that can only be investigated in vivo in intact organisms. Both types of models have therefore been important in the understanding of thyroid autoimmunity.
