Metabotropic glutamate receptor subtype 5 antagonism in learning and memory [PDF]

European Journal of Pharmacology, 2010
The role of the metabotropic glutamate receptor 5 (mGlu(5) receptor) in learning and memory and other behaviors are reviewed by examining the influence of selective antagonists and genetic knockout on performance. This receptor is involved in spatial learning, contextual fear conditioning, inhibitory avoidance, fear potentiated startle, and conditioned

Long-Term Depression of Striatal DA Release Induced by mGluRs via Sustained Hyperactivity of Local Cholinergic Interneurons

Frontiers in Cellular Neuroscience, 2021
The cellular mechanisms regulating dopamine (DA) release in the striatum have attracted much interest in recent years. By in vitro amperometric recordings in mouse striatal slices, we show that a brief (5 min) exposure to the metabotropic glutamate ...

Oligomers of Amyloid β Prevent Physiological Activation of the Cellular Prion Protein-Metabotropic Glutamate Receptor 5 Complex by Glutamate in Alzheimer Disease*

Journal of Biological Chemistry, 2016
The dysfunction and loss of synapses in Alzheimer disease are central to dementia symptoms. We have recently demonstrated that pathological Amyloid β oligomer (Aβo) regulates the association between intracellular protein mediators and the synaptic ...

An Appraisal of the Influence of the Metabotropic Glutamate 5 (mGlu5) Receptor on Sociability and Anxiety [PDF]

Frontiers in Molecular Neuroscience, 2019
Amongst the many neurotransmitter systems causally linked to the expression of social behavior, glutamate appears to play a pivotal role. In particular, metabotropic glutamate 5 (mGlu5) receptors have received much attention as its altered function has been reported in several mouse models of autism spectrum disorders and mental retardation. Inhibition

Metabotropic glutamate receptor 5 binding in male patients with alcohol use disorder

Translational Psychiatry, 2018
Glutamate signaling plays a major role in addiction. Preclinical research strongly suggests an implication of G-protein-coupled metabotropic glutamate receptor subtype 5 (mGluR5) in nicotine addiction and alcohol use disorder.

Ketamine, but not propofol, anaesthesia is regulated by metabotropic glutamate 5 receptors [PDF]

British Journal of Anaesthesia, 2006
Group I metabotropic glutamate receptors (mGluRs) have been reported to regulate N-methyl-d-aspartate (NMDA) receptor function in various brain regions. The selective mGluR5 antagonist 2-methyl-6-(phenylethynyl)-pyridine (MPEP) can potentiate NMDA antagonists such as PCP and MK-801-induced behavioural responses.

Genetic inactivation of mGlu5 receptor improves motor coordination in the Grm1crv4 mouse model of SCAR13 ataxia

Neurobiology of Disease, 2018
Deleterious mutations in the glutamate receptor metabotropic 1 gene (GRM1) cause a recessive form of cerebellar ataxia, SCAR13. GRM1 and GRM5 code for the metabotropic glutamate type 1 (mGlu1) and type 5 (mGlu5) receptors, respectively.

xCT-mediated glutamate excretion in white adipocytes stimulates interferon-γ production by natural killer cells in obesity

Cell Reports, 2023
Summary: Obesity-mediated hypoxic stress underlies inflammation, including interferon (IFN)-γ production by natural killer (NK) cells in white adipose tissue. However, the effects of obesity on NK cell IFN-γ production remain obscure.

Metabotropic glutamate receptor 5 in conditioned taste aversion learning [PDF]

Neurobiology of Learning and Memory, 2009
In conditioned taste aversion (CTA), animals learn to avoid a flavored solution (conditioned stimulus, CS) previously paired with internal malaise (unconditioned stimulus, US). Metabotropic glutamate receptor 5 (mGlu5) has been implicated in learning and memory processes and is necessary for CTA.

Participation of the Cholinergic System in Ameliorating Effect of Vasopressin Fragment by Group I Metabotropic Glutamate–Receptor Blockade

Journal of Pharmacological Sciences, 2008
The effect of [pGlu4,Cyt6,Arg8]-vasopressin fragment 4-9 (AVP4-9) on group I metabotropic glutamate (mGlu1) receptor antagonist–induced memory deficits was studied using 8-arm radial maze performance with 4 arms baited.
