Vasopressin (AVP) secretion and release are regulated by a number of central nervous system sites that receive peripheral signals from the osmoreceptors and baroreceptors. Aim of this paper is to review anatomical pathways and neurotransmitters involved as well as drugs affecting AVP secretion.
UNLABELLED A cohort of 66 healthy overweight and obese patients, 53 women and 13 men were examined. Waist circumference and fasting 25(OH)D, insulin, glucose, lipid (cholesterol, HDL cholesterol, and triglyceride), C-reactive protein (CRP), and complement 3 (C3), and 4 (C4) serum concentrations were measured. Insulin resistance was assessed by the(More)
The regulation of neurohypophyseal peptides secretion reflects the convergence of a large number of afferent neural pathways on vasopressinergic and oxytocinergic neurons of supraoptic (SON) and paraventricular nuclei (PVN). In addition to afferent input, vasopressin and oxytocin can also exert an autocrine regulation of neuronal activity. In fact,(More)
BACKGROUND Hereditary Coproporphyria (HCP) is characterized by abdominal pain, neurologic symptoms and psychiatric disorders, even if it might remain asymptomatic. The pathophysiology of both neurologic and psychiatric symptoms is not fully understood. Therefore, aiming to evaluate a possible role of brain blood flow disorders, we have retrospectively(More)
BACKGROUND Magnocellular neurosecretory neurons of the hypothalamic supraoptic (SON) and paraventricular (PVN) nuclei synthesize vasopressin and oxytocin in response to signals generated by osmoreceptors and baroreceptors and, respectively, by receptors of the nipples and cervix. METHODS We analyzed the literature identifying relevant articles dealing(More)
