Michael DISCOVERING THE ROLE OF AUTOINHIBITION IN KINETICS HETEROGENEITY OF EVOKEDABSTRACT DOPAMINE PAGE RESPONSES Han-Chen Wu, M.S. University of Pittsburgh, 2017 Dopamine (DA) contributes to critical functions in the central nervous system. By introducing electrical stimulation in vivo at the rat’s medial forebrain bundle, evoked DA signals can be measured at a carbon fiber electrode with fast scan cyclic voltammetry (FSCV) in rat’s dorsal striatum. Previously, evidence suggested that the heterogeneity in evoked DA responses reflects the difference in inherent kinetics, which might play an important role physiologically. A restricted diffusion based numerical model produced great fit between simulations and observed responses for stimulation lengths no longer than 3 seconds, using 4 or sometimes 3 adjustable parameters. A study was designed to explore different supra-physiological stimuli and examine these evoked responses in the dorsal striatum after raclopride, a D2 antagonist drug, was given. -

In astrocytes and microglia, MPEP depletes ATP. These findings seem to be self-contradictory, since ATP depletion is a fundamental stressor in ischemia. This study attempted to reconstruct the mechanism of MPEP-mediated ATP depletion and the consequences of ATP depletion on protection against ischemic injury. We compared the effects of MPEP and other mGluR5 negative modulators on ATP concentration when measured in rat hepatocytes and acellular solutions. We also evaluated the effects of mGluR5 blockade on viability in rat hepatocytes exposed to hypoxia. Furthermore, we studied the effects of MPEP treatment on mouse livers subjected to cold ischemia and warm ischemia reperfusion. -
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.

The G Protein-Coupled Glutamate Receptors As Novel Molecular Targets in Schizophrenia Treatment— a Narrative Review
Journal of Clinical Medicine Review The G Protein-Coupled Glutamate Receptors as Novel Molecular Targets in Schizophrenia Treatment— A Narrative Review Waldemar Kryszkowski 1 and Tomasz Boczek 2,* 1 General Psychiatric Ward, Babinski Memorial Hospital in Lodz, 91229 Lodz, Poland; [email protected] 2 Department of Molecular Neurochemistry, Medical University of Lodz, 92215 Lodz, Poland * Correspondence: [email protected] Abstract: Schizophrenia is a severe neuropsychiatric disease with an unknown etiology. The research into the neurobiology of this disease led to several models aimed at explaining the link between perturbations in brain function and the manifestation of psychotic symptoms. The glutamatergic hypothesis postulates that disrupted glutamate neurotransmission may mediate cognitive and psychosocial impairments by affecting the connections between the cortex and the thalamus. In this regard, the greatest attention has been given to ionotropic NMDA receptor hypofunction. However, converging data indicates metabotropic glutamate receptors as crucial for cognitive and psychomotor function. The distribution of these receptors in the brain regions related to schizophrenia and their regulatory role in glutamate release make them promising molecular targets for novel antipsychotics. This article reviews the progress in the research on the role of metabotropic glutamate receptors in schizophrenia etiopathology. Citation: Kryszkowski, W.; Boczek, T.

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. -
Research in Anxiety Disorders: from the Bench to the Bedside Matthew Garner A,⁎, Hanns Möhler B, Dan J
NEUPSY-10154; No of Pages 10 ARTICLE IN PRESS European Neuropsychopharmacology (2009) xx, xxx–xxx www.elsevier.com/locate/euroneuro REVIEW ARTICLE Research in anxiety disorders: From the bench to the bedside Matthew Garner a,⁎, Hanns Möhler b, Dan J. Stein c, Thomas Mueggler d, David S. Baldwin a a University of Southampton, UK b University of Zurich, Switzerland c University of Cape Town, South Africa d University and ETH of Zurich, Switzerland Received 13 January 2009; accepted 30 January 2009 KEYWORDS Abstract Anxiety; Treatment; The development of ethologically based behavioural animal models has clarified the anxiolytic Imaging; properties of a range of neurotransmitter and neuropeptide receptor agonists and antagonists, Cognition with several models predicting efficacy in human clinical samples. Neuro-cognitive models of human anxiety and findings from fMRI suggest dysfunction in amygdala-prefrontal circuitry underlies biases in emotion activation and regulation. Cognitive and neural mechanisms involved in emotion processing can be manipulated pharmacologically, and research continues to identify genetic polymorphisms and interactions with environmental risk factors that co-vary with anxiety-related behaviour and neuro-cognitive endophenotypes. This paper describes findings from a range of research strategies in anxiety, discussed at the recent ECNP Targeted Expert Meeting on anxiety disorders and anxiolytic drugs. The efficacy of existing pharmacological treatments for anxiety disorders is discussed, with particular reference to drugs modulating serotonergic, noradrenergic and gabaergic mechanisms, and novel targets including glutamate, CCK, NPY, adenosine and AVP. Clinical and neurobiological predictors of active treatment and placebo response are considered. © 2009 Published by Elsevier B.V. Anxiety symptoms are common in the community, and typically persist for many years, and are associated with anxiety disorders are common in primary and secondary significant personal distress, reduced quality of life, medical care settings (King et al., 2008). -
