General comments on tissue sensitivity to thyroid hormones in starvation
Abstract:
The interrelationship between thyroid hormones and catecholamines is discussed. It is known that hypothyroidism will decrease tissue sensitivity to exogenous catecholamines. There is, however, no experimental proof that the thyroid hormones changes, particularly the low serum T(3) levels encountered in systemic illness and starvation, are sufficient to change tissue sensitivity to catecholamines. Catecholamines and thyroid hormones influence thermogenesis. Recently a decreased effectiveness of thyroid hormones in the starving hypothyroid rat has been documented. It has, however, not been excluded that part of this change is due to a combined change in effectiveness of thyroid hormones and catecholamines on thermogenesis.

Synthesis and Regulation of Thyroid Hormones
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...
Functions of Thyroid Hormones
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
