Sex steroid and glucocorticoid receptors in the bursa of Fabricius of obese strain chickens spontaneously developing autoimmune thyroiditis

Abstract

The female sex develops autoimmune disease far more often than the male. This is claimed to be due to differences in peripheral sex steroid levels. We have examined in the bursa of Fabricius of Obese strain (OS) chickens, which spontaneously develop autoimmune thyroiditis, as well as in their healthy counterparts androgen(AR)-, estrogen(ER)-, progestin(PR)- and glucocorticoid(GR)-receptors in an attempt to elucidate possible further pathomechanisms, namely at the target site of steroid hormones. The characterization (affinity, specificity, association- and dissociation-rate, sedimentation behaviour) of all four types of receptors revealed no difference between sex or strain. Furthermore, the ontogeny study of the receptor capacity and affinity from the 7th embryonic day (i.e. before lymphocyte settlement) until bursa involution, again showed no difference between OS and healthy chickens of either sex. Thus, it can be concluded that the principal sex dependency of the susceptibility to autoimmune disease results predominantly from differences in sex steroid levels per se, although alterations in mechanisms beyond the cytosolic receptor level can presently not be excluded.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.
