Using 125I-interleukin-1 beta (125I-IL-1 beta) as a ligand, a specific receptor of high affinity dissociation constant (1.1 +/- 0.2 x 10(-10) M) with binding sites (350 +/- 40/cell) for interleukin-1 beta (IL-1 beta) has been demonstrated on cultured porcine thyroid cells. IL-1 alpha almost equally cross-reacted with the receptor (Kd = 1.2 +/- 0.3 x 10(-10) M and 350 +/- 50 binding sites/cell). TSH, IL-2 and other peptide hormones did not inhibit the binding of 125I-IL-1 beta to thyroid cells. Crosslinking study revealed a major band (approximately 95 kD) with a corrected molecular mass of approximately 78 kD. Moreover, both IL-1 beta and IL-1 alpha stimulated prostaglandin E2 production of cultured porcine thyroid cells, although the potency of IL-1 alpha was slightly greater than that of IL-1 beta. These results suggest that IL-1 may be involved in the regulation of thyroid cell function.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013961 Thyroid Gland A highly vascularized endocrine gland consisting of two lobes joined by a thin band of tissue with one lobe on each side of the TRACHEA. It secretes THYROID HORMONES from the follicular cells and CALCITONIN from the parafollicular cells thereby regulating METABOLISM and CALCIUM level in blood, respectively.

D017472 Receptors, Interleukin-1 Cell surface receptors that are specific for INTERLEUKIN-1. Included under this heading are signaling receptors, non-signaling receptors and accessory proteins required for receptor signaling. Signaling from interleukin-1 receptors occurs via interaction with SIGNAL TRANSDUCING ADAPTOR PROTEINS such as MYELOID DIFFERENTIATION FACTOR 88.
