Pulsatile arginine vasopressin release from the rat hypothalamo neurohypophyseal system during osmotic stimulation.
Arginine vasopressin (AVP) was released in vitro in a pulsatile pattern from the hypothalamo-neurohypophyseal system (HNS) and from the hypothalamus during continuous hyperosmotic stimuli with NaCl or fructose. No significant difference was found in the AVP pulse frequency between the two kinds of hyperosmotic agents. AVP was released from the HNS in a dose-related manner under NaCl stimulation...
متن کاملDehydration-induced proteome changes in the rat hypothalamo-neurohypophyseal system.
The hypothalamo-neurohypophyseal system (HNS) mediates neuroendocrine responses to dehydration through the action of the antidiuretic hormone vasopressin (VP). VP is synthesized as part of a prepropeptide in magnocellular neurons of the hypothalamic supraoptic nucleus (SON) and paraventricular nucleus. This precursor is processed during transport to axon terminals in the posterior pituitary gla...
متن کاملThe Nature of Hypothalamo-neurohypophyseal Neurosecretion in the Rat
The nature of hypothalamo-neurohypophyseal neurosecretion was examined in the rat by means of intraventricular injections of tritiated amino acids. Quantitation of autoradiographs was used at the light microscope level to study the sites of synthesis of proteins and their time of arrival in the neural lobe. Electron microscope autoradiographs were used to study the labeling of neural lobe tissu...
متن کاملRole of non-NMDA receptors in vasopressin and oxytocin release from rat hypothalamo-neurohypophysial explants.
Glutamate is recognized as a prominent excitatory transmitter in the supraoptic nucleus (SON) and is involved in transmission of osmoregulatory information from the osmoreceptors to the vasopressin (VP) and oxytocin (OT) neurons. Explants of the hypothalamo-neurohypophysial system were utilized to characterize the roles of the non-N-methyl-D-aspartate (NMDA) glutamate receptor subtypes (non-NMD...
متن کاملGalanin influences vasopressin and oxytocin release from the hypothalamo-neurohypophysial system of salt loaded rats.
Galanin is a peptide present in the nervous system and peripheral tissues which exerts a broad range of physiological functions. The influence of centrally administered galanin (Gal; 100 pM i.c.v.) on arginine vasopressin (AVP) and oxytocin (OT) content in the hypothalamus and neurohypophysis as well as on their blood plasma concentration was estimated in male Wistar rats drinking ad libitum 2%...
