Image Parathyroid gland high mag cropped.jpg thumb right 350px Micrograph of a parathyroid gland . H&E stain . Parathyroid chief cells also called parathyroid principal cells or simply parathyroid cells are cell biology cells in the parathyroid gland s which produce parathyroidhormone . The end result of increased secretion by the chief cell s of a parathyroid gland is an increase in the blood plasma serum level of Calcium . 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. This mechanism is critically important, as it describes a physiological feed back loop by which parathyroidhormone secretion is down regulated in response to a restoration of serum calcium.

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 .

A hormone receptor is a receptor protein on the surface of a cell or in its interior that binds to a specific hormone . The hormone causes many changes to take place in the cell. Binding of hormones to hormone receptors often trigger the start of a biophysical signal that can lead to further signal transduction pathway s, or trigger the activation or inhibition of genes. ref http www.bio balance.com Graphics.htm http www.bio balance.com Bot generated title ref Types of Hormone Receptors 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. 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 .
