Abstract. The modern views on the anatomical and physiological interactions between the hypothalamus, pituitary and thyroid gland have emerged only in the last fifty years, although their historical roots may be found in a number of ancient and still poorly known ideas and observations. The avian thyroid gland is primarily under the control of the hypothalamic-pituitary-thyroid axis. The hypothalamus produces 2 hormones, thyrotropin-releasing hormone (TRH)and somatostatin,both having stimulatory andinhibitory effects on the pituitary. TSH, which is produced by thyrotrophs in the anterior pituitary, is the major controller of the production and release of thyroid hormones by

1/02/2010 · These data identify the hypothalamic–pituitary–thyroid axis as an important target of the metabolic actions of JNK1. The thyroid hormone pathway is negatively regulated by JNK1. The increased amount of T4 and T3 in the blood of N KO mice compared with N WT mice correlates with increased expression of hypothalamic TRH and pituitary gland TSH. lin on the hypothalamic-pituitary-thyroid axis of nondiabetic rats and diabetic animals with streptozotocin models of acute and mild type 1 diabetes mellitus. This treatment was carried out for 28 days in acute (daily does of 0.3, 0.6, and 1.5IU of insulin per rat) and for 135 days in mild diabetes (daily dose of 0.45IU/rat). Nondiabetic rats were treated in a similar manner. Intrana-sal

Study of healthy aging of the hypothalamic-pituitary-thyroid axis is difficult, since aging is accompanied by the increased frequency of various thyroid diseases and of extrathyroidal disease, as well as by the increased intake of medicines modulating the function of this axis. Specifically, the hypothalamic-pituitary axis directly affects the functions of the thyroid gland, the adrenal gland, and the gonads, as well as influencing growth, milk production, and water balance .

The skin is commonly affected in thyroid diseases, but the mechanism for this association is still unclear. As the skin expresses numerous neuroendocrine elements, we tested the additional cutaneous expression of mediators operating in the hypothalamic–pituitary–thyroid axis. of a pivotal role for the thyroid hormone receptor beta in negative feedback of TH on the hypothalamic and pituitary level.
