Gene regulation in the magnocellular hypothalamo-neurohypophysial system.
The hypothalamo-neurohypophysial system (HNS) is the major peptidergic neurosecretory system through which the brain controls peripheral physiology. The hormones vasopressin and oxytocin released from the HNS at the neurohypophysis serve homeostatic functions of water balance and reproduction. From a physiological viewpoint, the core question on the HNS has always been, "How is the rate of horm...
متن کاملModel Roles of the Hypothalamo-Neurohypophysial System in Neuroscience Study
Studies on the Hypothalamo-Neurohypophysial System (HNS) have played a pivotal role in establishing the fundamental principles of neuroscience. Examples include the identification of excitation-secretion coupling, coexistence of peptides-containing large dense core vesicles with classical neurotransmitters, neuronal-glial interactions, functionsassociated morphological plasticity, and domain-sp...
متن کاملFluorescent visualization of oxytocin in the hypothalamo-neurohypophysial system
Oxytocin (OXT) is well known for its ability to the milk ejection reflex and uterine contraction. It is also involved in several other behaviors, such as anti-nociception, anxiety, feeding, social recognition, and stress responses. OXT is synthesized in the magnocellular neurosecretory cells (MNCs) in the hypothalamic paraventricular (PVN) and the supraoptic nuclei (SON) that terminate their ax...
متن کاملThe hypothalamo-neurohypophysial response to melatonin.
The present paper reviews the findings accumulated on the role of pineal gland and its hormone - melatonin - in regulation of the hypothalamo-neurohypophysial system activity. Effects of modified photoperiod, pinealectomy or treatment with melatonin on the vasopressin and oxytocin biosynthesis and/or secretion have been described. Taken together, the in vivo and in vitro data suggest that the e...
متن کاملThyrotropin-releasing hormone modulates vasopressin and oxytocin synthesis and release from the hypothalamo-neurohypophysial system of different age male rats.
Thyrotropin-releasing hormone (TRH) is engaged in the modulation of the hypothalamo-neurohypophysial system activity. Effects of repeated intravenously injections of TRH in a dose of 100 ng/100 g b.w. on vasopressin (VP) and oxytocin (OT) biosynthesis and release from the hypothalamo-neurohypophysial system was investigated in rats in different age (1-, 3- or 7-months of the life). To estimate ...
