NMDA Receptor Dynamics Dictate Neuronal Plasticity and Function
NMDA Receptor Dynamics Dictate Neuronal Plasticity and Function Tommy Weiss Sadan, Ph.D. and Melanie R. Grably, Ph.D. N-Methyl-D-Aspartate Receptor (NMDAR) are ubiquitously expressed along the central nervous system and are instrumental to various physiological processes such as synaptic plasticity and learning. Nevertheless, several mental disabilities including schizophrenia and Alzheimer’s disease are all related to NMDAR dysfunction. Here, we review many aspects of NMDAR function and regulation and describe their involvement in pathophysiological states using Alomone Labs products. Right: Cell surface detection of GluN2B in rat hippocampal neurons. Introduction Mechanism of Action Glutamate is a key neuro-transmitter in the central nervous system and NMDAR activation depends on sequential conformational changes to acts on a variety of cell surface receptors, collectively termed ionotropic relieve the magnesium blockade which is achieved by rapid membrane glutamate receptors (iGluRs)15.

This in are members of the iGluR superfamily and are pivotal to many physiological turn removes the inhibitory electrostatic forces of magnesium and enables processes such as the formation of long term memory, synaptic plasticity calcium influx and transmission of long lasting signals (i.e. long-term and many other cognitive functions. Therefore, it is not surprising that potentiation), a key mechanism to learning and memory formation10. -
Metabotropic Glutamate Receptors
mGluR Metabotropic glutamate receptors mGluR (metabotropic glutamate receptor) is a type of glutamate receptor that are active through an indirect metabotropic process. They are members of thegroup C family of G-protein-coupled receptors, or GPCRs. Like all glutamate receptors, mGluRs bind with glutamate, an amino acid that functions as an excitatoryneurotransmitter. The mGluRs perform a variety of functions in the central and peripheral nervous systems: mGluRs are involved in learning, memory, anxiety, and the perception of pain. mGluRs are found in pre- and postsynaptic neurons in synapses of the hippocampus, cerebellum, and the cerebral cortex, as well as other parts of the brain and in peripheral tissues. Eight different types of mGluRs, labeled mGluR1 to mGluR8, are divided into groups I, II, and III. Receptor types are grouped based on receptor structure and physiological activity. www.MedChemExpress.com 1 mGluR Agonists, Antagonists, Inhibitors, Modulators & Activators (-)-Camphoric acid (1R,2S)-VU0155041 Cat.

Box 1346 Ann Arbor, Ml 48106-1346 Abstract Nitric oxide (NO) has emerged as an ubiquitous signaling molecule in the central nervous system (CNS). NO is synthesised from molecular oxygen and the amino acid L-arginine (L- ARG) by the enzyme NO synthase (NOS), and the availability of L-ARG has been implicated as the limiting factor for NOS activity. Previous studies have indicated that L- ARG is localised in astrocytes in vitro and that the in vitro activation of non-N-methyl-D- aspartate (NMDA) receptors, as well as the presence of peroxynitrite (ONOO ), led to the release of L-ARG. Microdialysis was therefore used in this study to investigate whether this held true in vivo. -

PRODUCT INFORMATION Fantofarone Item No. 26381 CAS Registry No.: 114432-13-2 Formal Name: 3,4-dimethoxy-N-methyl-N-[3-[4-[[2- N (1-methylethyl)-1-indolizinyl]sulfonyl] O phenoxy]propyl]-benzeneethanamine S O Synonym: SR 33557 MF: C31H38N2O5S FW: 550.7 Purity: ≥98% N O UV/Vis.: λmax: 233, 304 nm Supplied as: A crystalline solid O Storage: -20°C O Stability: ≥2 years Information represents the product specifications. Batch specific analytical results are provided on each certificate of analysis. Laboratory Procedures Fantofarone is supplied as a crystalline solid. A stock solution may be made by dissolving the fantofarone in the solvent of choice. Fantofarone is soluble in organic solvents such as DMSO and dimethyl formamide, which should be purged with an inert gas. The solubility of fantofarone in these solvents is approximately 10 mg/ml. Description Fantofarone is a calcium channel inhibitor.1 It selectively inhibits the L-type voltage-gated calcium channel in isolated rat aorta (IC50 = 0.61 nM) over α1- and β-adrenergic, muscarinic, and histamine H2 receptors in rat heart homogenates (IC50s = >10, >10, 4, and >10 µM, respectively), and the serotonin receptor subtypes 5-HT1 and 5-HT2, as well as histamine H1 and adenosine A1 receptors, in rat brain homogenates (IC50s = >10, 4, >10, and >10 µM, respectively). Fantofarone inhibits peak calcium current in depolarized 2 and hyperpolarized L-type voltage-gated calcium channels (IC50s = 1.4 and 150 nM, respectively). It inhibits potassium chloride- and norepinephrine-induced contractions in isolated rat aorta (IC50s = 5.64 and 96 nM, respectively).1 It enhances recovery of cardiac output during reperfusion of isolated rat hearts when used at a concentration of 10 nM.3 Fantofarone prevents angioplasty-induced vasospasms in the femoral artery in a rabbit model of focal atherosclerosis when administered at a dose of 50 µg/kg.4 References 1. -

Glutamate and Microglia Activation As a Driver of Dendritic Apoptosis: a Core Pathophysiological Mechanism to Understand Schizop
Parellada and Gassó Translational Psychiatry (2021) 11:271 https://doi.org/10.1038/s41398-021-01385-9 Translational Psychiatry PERSPECTIVE Open Access Glutamate and microglia activation as a driver of dendritic apoptosis: a core pathophysiological mechanism to understand schizophrenia Eduard Parellada 1,2,3 and Patricia Gassó 1,2,4 Abstract Schizophrenia disorder remains an unsolved puzzle. However, the integration of recent findings from genetics, molecular biology, neuroimaging, animal models and translational clinical research offers evidence that the synaptic overpruning hypothesis of schizophrenia needs to be reassessed. During a critical period of neurodevelopment and owing to an imbalance of excitatory glutamatergic pyramidal neurons and inhibitory GABAergic interneurons, a regionally-located glutamate storm might occur, triggering excessive dendritic pruning with the activation of local dendritic apoptosis machinery. The apoptotic loss of dendritic spines would be aggravated by microglia activation through a recently described signaling system from complement abnormalities and proteins of the MHC, thus implicating the immune system in schizophrenia. Overpruning of dendritic spines coupled with aberrant synaptic plasticity, an essential function for learning and memory, would lead to brain misconnections and synaptic inefficiency underlying the primary negative symptoms and cognitive deficits of schizophrenia. This driving hypothesis has relevant therapeutic implications, including the importance of pharmacological interventions during
