Augmented Cystine–Glutamate Exchange by Pituitary Adenylate Cyclase-activating Polypeptide Signaling via the VPAC1 Receptor [PDF]

open access: yes, 2014
In the central nervous system, cystine import in exchange for glutamate through system xc- is critical for the production of the antioxidant glutathione by astrocytes, as well as the maintenance of extracellular glutamate. Therefore, regulation of system

Neuronal hyperexcitability: A key to unraveling hippocampal synaptic dysfunction in Lafora disease

open access: yesEpilepsia, EarlyView.
Abstract Background and Objective Lafora disease (LD) is a rare progressive disorder caused by mutations in the EPM2A or EPM2B genes, characterized by the accumulation of Lafora bodies, drug‐resistant epilepsy, and cognitive decline. To investigate the early molecular mechanisms of LD, we studied electrophysiological changes in the dentate gyrus (DG ...

Acute Ketamine Infusion in Rat Does Not Affect In Vivo [C]ABP688 Binding to Metabotropic Glutamate Receptor Subtype 5

open access: yesMolecular Imaging, 2018
Detecting changes in metabotropic glutamate receptor 5 (mGluR5) availability through molecular imaging with the positron emission tomography (PET) tracer [ 11 C]ABP688 is valuable for studying dysfunctional glutamate transmission associated with ...

Repeated \u3cem\u3eN\u3c/em\u3e-Acetylcysteine Administration Alters Plasticity-Dependent Effects of Cocaine [PDF]

open access: yes, 2007
Cocaine produces a persistent reduction in cystine–glutamate exchange via system xc− in the nucleus accumbens that may contribute to pathological glutamate signaling linked to addiction.

Lower density of calretinin‐immunopositive neurons in the putamen of subjects with schizophrenia

open access: yesJournal of Anatomy, Volume 246, Issue 4, Page 505-516, April 2025.
Recent neuroimaging and histological studies highlight the striatum as a key area involved in SCH, but the specific impairment of neuronal subtypes in subcortical structures is not fully understood. This study is the first detailed investigation of neuroanatomical changes in the putamen in SCH, specifically examining the density of calretinin ...

An expanding range of targets for kynurenine metabolites of tryptophan [PDF]

open access: yes, 2013
The kynurenine pathway of tryptophan metabolism accounts for most of the tryptophan that is not committed to protein synthesis and includes compounds active in the nervous and immune systems.

Effect of novel metabotropic glutamate receptor 5 antagonist on gastroesophageal reflux in dogs during anaesthesia

open access: yesJournal of Small Animal Practice, EarlyView.
Objectives Gastroesophageal reflux during anaesthesia is a common event occurring in dogs with the potential to cause oesophageal injury and aspiration pneumonia. The objective of the current study was to evaluate the effect of the novel metabotropic glutamate receptor 5 antagonist TT001 on gastroesophageal reflux during anaesthesia in dogs using two ...

Binge drinking triggers VGLUT3-mediated glutamate secretion and subsequent hepatic inflammation by activating mGluR5/NOX2 in Kupffer cells

open access: yesNature Communications
Glutamate, a crucial player in hepatic amino acid metabolism, has been relatively unexplored in immune cell activation. We show in a study with male mice that hepatic glutamate accumulates in vesicles of perivenous hepatocytes through vesicular glutamate

How copy number variations shape brain developmental disorders: Unraveling the synaptic puzzle

open access: yesPsychiatry and Clinical Neurosciences, EarlyView.
Neurodevelopmental disorders (NDDs), such as schizophrenia (SCZ), Attention‐deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), learning disabilities, and intellectual disabilities (ID), are highly prevalent. One significant genetic factor associated with NDDs is copy number variations (CNVs), which are structural changes in the ...

A combinatorial approach of Proteomics and Systems Biology in unravelling the mechanisms of acute kidney injury (AKI): involvement of NMDA receptor GRIN1 in murine AKI [PDF]

open access: yes, 2013
BACKGROUND: Acute kidney injury (AKI) is a frequent condition in hospitalised patients undergoing major surgery or the critically ill and is associated with increased mortality.
