Voltage-induced Ca release by ryanodine receptors causes neuropeptide secretion from nerve terminals
Velazquez-Marrero C, Custer E, Marrero H, Ortiz-Miranda S, Lemos J
J Neuroendocrinol
. 2020 Apr;
32(4):e12840.
PMID: 32227430
Depolarisation-secretion coupling is assumed to be dependent only on extracellular calcium ([Ca ] ). Ryanodine receptor (RyR)-sensitive stores in hypothalamic neurohypophysial system (HNS) terminals produce sparks of intracellular calcium ([Ca...

. 2020 Jan;
32(4):e12826.
PMID: 31917875
Hypothalamic magnocellular neuroendocrine cells have unique electrical properties and a remarkable capacity for morphological and synaptic plasticity. Their large somatic size, their relatively uniform and dense clustering in the supraoptic...

PMID: 29512852
Many different types of purinergic receptors are present in the Hypothalamic-Neurohypophysial System (HNS), which synthesizes and releases vasopressin and oxytocin. The specific location of purinergic receptor subtypes has important functional...

Alcohol Clin Exp Res
. 2015 Sep;
39(9):1671-9.
PMID: 26331878
Background: Alcoholics have been reported to have reduced levels of magnesium in both their extracellular and intracellular compartments. Calcium-dependent potassium channels (BK) are known to be one of ethanol (EtOH)'s...

J Gen Physiol
. 2014 May;
143(6):693-702.
PMID: 24863930
Highly localized Ca(2+) release events have been characterized in several neuronal preparations. In mouse neurohypophysial terminals (NHTs), such events, called Ca(2+) syntillas, appear to emanate from a ryanodine-sensitive intracellular Ca(2+)...

. 2014 Mar;
34(10):3733-42.
PMID: 24599471
μ-Opioid agonists have no effect on calcium currents (I(Ca)) in neurohypophysial terminals when recorded using the classic whole-cell patch-clamp configuration. However, μ-opioid receptor (MOR)-mediated inhibition of I(Ca) is reliably demonstrated...

. 2013 Sep;
229(3):333-42.
PMID: 24037803
Arginine-vasopressin (AVP) plays a major role in maintaining cardiovascular function and related pathologies. The mechanism involved in its release into the circulation is complex and highly regulated. Recent work has...

. 2013 Feb;
37(6):933-40.
PMID: 23421938
Background: Voltage-gated calcium channels (VGCCs) in rat neurohypophysial terminals exhibit molecular tolerance to alcohol, including desensitization to the drug and increased current density, after 3 weeks of alcohol drinking. Moreover,...

PMID: 23357790
The mitochondria are critical for steroidogenesis since the ability of cholesterol to move into mitochondria to be available for cytochrome P450, CYP11A1, determines the efficacy of steroid production. Several proteins...

PMID: 22341671
The hypothalamic-neurohypophysial system (HNS) controls diuresis and parturition through the release of arginine-vasopressin (AVP) and oxytocin (OT). These neuropeptides are chiefly synthesized in hypothalamic magnocellular somata in the supraoptic and...
