Contribution of astrocytes to synaptic transmission in the rat supraoptic nucleus

Neurochemistry International, 2004
Astrocytes, besides supporting metabolic and scaffolding functions, play a prominent role in the modulation of neuronal communication. In particular, they are responsible for clearing synaptically-released glutamate via highly specific transporters located on their plasma membrane.

Modulation of synaptic transmission by astrocytes in the rat supraoptic nucleus

Journal of Physiology-Paris, 2002
One of the functions of astroglial cells in the central nervous system is to clear synaptically-released glutamate from the extracellular space. This is performed thanks to specific transporters of the excitatory amino acid expressed on their surface.

Effects of water deprivation and rehydration on c-Fos and FosB staining in the rat supraoptic nucleus and lamina terminalis region.

American Journal of Physiology. Regulatory Integrative and Comparative Physiology, 2005
We studied cFos and FosB staining in the supraoptic nucleus (SON) the organum vasculosum of the lamina terminalis (OVLT) and the median preoptic nucleus (MnPO) in adult male rats after water deprivation (24 h, n = 11; 48 h, n = 12) and water deprivation ...

Pre- and postnatal synaptogenesis in the rat supraoptic nucleus

Peptides, 1980
Abstract The first synapses in the rat SON appear at fetal day 17; their number increases steadily to reach adult levels at postnatal day 25. Asymmetrical synapses are typical in the fetal SON, whereas throughout postnatal development symmetrical synapses occur more frequently and are characteristic of the adult SON.

ULTRASTRUCTURE OF NEUROSECRETORY CELLS IN THE SUPRAOPTIC NUCLEUS OF THE DOG AND RAT

Journal of Endocrinology, 1965
SUMMARY The hypothalamo-neurohypophysial systems of the dog and rat have been investigated with the electron microscope. The best preparations were obtained from anaesthetized animals cooled to about 7°. Neuronal cell bodies in the supraoptic nuclei of the dog were characterized both by their size, by their occasional proximity to the ...

Microarray screening of suppression subtractive hybridization-PCR cDNA libraries identifies novel RNAs regulated by dehydration in the rat supraoptic nucleus.

Physiological Genomics, 2006
The magnocellular neurons (MCNs) of the supraoptic nucleus (SON) and paraventricular nucleus (PVN) of the hypothalamus are the principal site of biosynthesis of prepropeptide precursor of the antidiuretic hormone vasopressin (VP).

Cell loss in supraoptic and paraventricular nucleus in Alzheimer's disease

Brain Research, 1993
Previous studies have shown an activation of the hypothalamo-neurohypophyseal system (HNS) in normal aging and in senile dementia. Among other explanations, this activation might be secondary to cell loss in the supraoptic (SO) and paraventricular (PV) nuclei.

Nicotine facilitates noradrenaline release in the rat supraoptic nucleus

Neuroreport, 2001
Nicotine injected in the supraoptic nucleus facilitates vasopressin release from the neurohypophysis. Nicotinic acetylcholine receptors have been found not only on vasopressin-producing cell bodies but also on presynaptic nerve terminals in the nucleus. Vasopressin cells receive excitatory synaptic inputs from noradrenergic neurones.

Neuronal loss and plasticity in the supraoptic nucleus in Parkinson's disease

Neurology, 1997
Disturbed circadian control of renal water excretion and blood pressure adaptation in Parkinson's disease (PD) suggest impaired hypothalamic magnocellular neurosecretion. To test the hypothesis that this may relate to specific hypothalamic pathology in PD, we studied morphometrically the neuronal population of the supraoptic nucleus (SON) in PD ...
