Brain‐Derived Neurotrophic Factor‐Tyrosine Kinase B Pathway Mediates NMDA Receptor NR2B Subunit Phosphorylation in the Supraoptic Nuclei Following Progressive Dehydration
F. R. Carreño,Joseph D. Walch,Joseph D. Walch,Mayurika Dutta,Thekkethil Prashant Nedungadi,J. Cunningham +5 more
TL;DR: In this paper, the effects of water deprivation (WD) on the phosphorylation of tyrosine kinase B (TrkB) and NMDA receptor subunits in the supraoptic nucleus (SON) of the rat were studied.
Journal ArticleDOI
Somatodendritic dynorphin release: orchestrating activity patterns of vasopressin neurons.
TL;DR: It is shown that neuropeptide release from the soma and dendrites of vasopressed neurons activates vasopressin receptors and kappa-opioid receptors to cause activity-dependent modulation of vasobressin neuron activity, and that this is essential for activity patterning in vasoppressin neurons.
Journal ArticleDOI
Intracellular calcium increase and somatodendritic vasopressin release by vasopressin receptor agonists in the rat supraoptic nucleus: involvement of multiple intracellular transduction signals.
TL;DR: The V2 agonist activation of both PLC and AC pathways could result from an action on the PLC‐linked unknown receptor, and/or the AC‐linked dual angiotensin II‐vasopressin receptor.

Regulation of transmitter release by high-affinity group III mGluRs in the supraoptic nucleus of the rat hypothalamus.
TL;DR: Group III mGluR8, because of their high affinity for glutamate, are particularly well suited to detect small changes in the concentration of this excitatory amino acid in the extracellular space and may favor the negative feedback control exerted by glutamate on its own release as well as the intersynaptic crosstalk mediated by glutamate spillover on adjacent synapses.

Localization and osmotic regulation of vesicular glutamate transporter-2 in magnocellular neurons of the rat hypothalamus.
Erik Hrabovszky,Á.K. Csapó,Imre Kalló,Imre Kalló,Tamás Wilheim,Gergely F. Turi,Zs. Liposits,Zs. Liposits +7 more
TL;DR: Evidence is presented that magnocellular oxytocin as well as vasopressin cells contain the glutamatergic marker vesicular glutamate transporter-2, similarly to most of the parvicellular neurosecretory neurons examined so far, and novel mechanisms whereby glutamate of endogenous sources can regulate mag nocellular neuronal functions are suggested.

Expression of c-fos protein in brain: metabolic mapping at the cellular level
TL;DR: Fos immunohistochemistry provides a cellular method to label polysynaptically activated neurons and thereby map functional pathways in response to polysynaptic activation.

A potent and selective endogenous agonist for the mu-opiate receptor.
TL;DR: The discovery and isolation from brain of a peptide, endomorphin-1 (Tyr-Pro-Trp-Phe-NH2), which has the highest specificity and affinity for the µ receptor of any endogenous substance so far described and they maybe natural ligands for this receptor.

The organization of noradrenergic pathways from the brainstem to the paraventricular and supraoptic nuclei in the rat
TL;DR: The autoradiographic material, and additional double-labeling experiments, were used to identify and to characterize projections that interconnect the A1, A2 and A6 regions, as well as possible projections from these cell groups to the spinal cord.

TL;DR: The extremely high concentrations and widespread distribution of neuropeptide Y in the central nervous system suggests a number of important physiological roles for this neurotransmitter candidate.

Differential co-existence of neuropeptide Y (NPY)-like immunoreactivity with catecholamines in the central nervous system of the rat.
TL;DR: The findings indicate that central catecholamine neurons can be subdivided into distinct sub-groups based upon the coexistence of a specific peptide.
