Parathyroid chief cells constitute one of the few cell types of the body that regulate intracellular calcium levels as a consequence of extracellular or serum changes in calcium concentration. The calcium sensing receptor CaSR is sensitive to an increase in serum calcium, and stimulates the uptake of calcium by the parathyroid chief cell.

A hormone receptor is a molecule that can bind to a specific hormone . Receptors for peptide hormones tend to be found on the cell membrane plasma membrane of cells, whereas receptors for lipophillicity lipid soluble hormones are usually found within the cytoplasm . Upon hormone binding, the receptor can initiate multiple signaling pathways which ultimately lead to changes in the behaviour of the target cells. Peptide hormone receptors Many hormones are composed of peptides polypeptides , e.g. thyroid stimulating hormone , follicle stimulating hormone , leutinizing hormone and insulin . These molecules are not lipid soluble and therefore cannot molecular diffusion diffuse through cell membranes. Consequently, receptors for peptide hormones are located on the plasma membrane. Peptide hormone receptors are often transmembrane protein s. They are also called G protein coupled receptor s, sensory receptor s or ionotropic receptor s. These receptors generally function via intracellular second messengers , including cyclic AMP cAMP , inositol 1,4,5 trisphosphate Inositol triphosphate IP3 and the Calcium signaling calcium Ca sup 2 sup calmodulin system. Lipid soluble hormone receptors Steroid hormone receptor s and related receptors are generally soluble proteins that function through gene activation. Their response elements are DNA sequences promoters that are bound by the complex of the steroid bound to its receptor. The receptors themselves are zinc finger proteins. ref http users.rcn.com jkimball.ma.ultranet BiologyPages S SteroidREs.html Steroid Hormone Receptors and their Response Elements ref These receptors include those for Glucocorticoid glucocorticoids , estrogen s, androgen s, thyroid hormone T3 , calcitriol the active form of vitamin D , and the retinoid s vitamin A .

distinguish Release factor A releasing hormone or releasing factor is a hormone whose main purpose is to control the release of another hormone. The main releasing hormones secreted by the hypothalamus are Thyrotropin releasing hormone TRH , Corticotropin releasing hormone CRH , Gonadotropin releasing hormone GnRH , Growth hormone releasing hormone GHRH , Two other factors are also classed as releasing hormones, although they in fact inhibit pituitary hormone release Somatostatin , Dopamine . For example, TRH is released from the hypothalamus in response to low levels of secretion of thyroid stimulating hormone TSH from the pituitary gland . The TSH in turn is under feedback control by the thyroid hormones Thyroxine T4 and Triiodothyronine T3 . When the levels of TSH are too high, they feed back on the brain to shut down the secretion of TRH. Synthetic TRH is also used by physicians as a test of TSH reserve in the pituitary gland as it should stimulate the release of TSH and prolactin from this gland. Releasing hormones are sometimes known as liberins. For example, TRH may be known as thyroliberin. Inhibiting hormones may be known as statins. For example, dopamine which inhibits prolactin release may be called prolactostatin. Mechanism Releasing hormones increase or, in case of inhibitory factors, decrease the intracellular concentration of calcium Ca sup 2 sup , resulting in vesicle fusion of the respective primary hormone. For GnRH, TRH and GHRH the increase in Ca sup 2 sup is achieved by the releasing hormone coupling and activating G protein coupled receptors coupled to the Gq alpha subunit G sub q sub alpha subunit , activating the IP3 DAG pathway to increase Ca sup 2 ... and Medicine in 1977 for their contributions to understanding the peptide hormone production ... 11 Fulltext .

It is a 44 ref name GeneGlobe amino acid peptide hormone produced in the arcuate nucleus of the hypothalamus . GHRH first appears in the human hypothalamus between 18 and 29 weeks of gestation, which corresponds to the start of production of growth hormone and other somatotropes in fetuses. ref name GeneGlobe Origin GHRH is released from neurosecretory nerve terminals of these arcuate neurons, and is carried by the hypothalamo hypophyseal portal system to the anterior pituitary gland where it stimulates growth hormone GH secretion by stimulating the growth hormone releasing hormone receptor . GHRH is released in a pulsatile manner, stimulating similar pulsatile release of GH. In addition, GHRH also promotes slow wave sleep directly. ref cite journal author Ob l F, Krueger J title The somatotropic axis and sleep. journal Rev Neurol Paris volume 157 issue 11 Pt 2 pages S12 5 year 2001 pmid 11924022 ref Growth hormone is required for normal postnatal growth, bone growth, regulatory effects on protein, carbohydrate, and lipid metabolism. ref name GeneGlobe https www1.qiagen.com ... pituitary.
