Absence seizures: Update on signaling mechanisms and networks

Epilepsia Open, EarlyView.
Abstract Absence seizures (AS) are a hallmark of genetic generalized epilepsies (GGE), characterized by brief episodes of impaired consciousness accompanied by electroencephalographic spike‐and‐wave discharges (SWDs). Traditionally attributed to cortico‐thalamo‐cortical (CTC) dysrhythmia, emerging evidence suggests a more intricate pathophysiological ...

Type 1 metabotropic glutamate receptors (m G lu1) trigger the gating of G lu D 2 delta glutamate receptors [PDF]

EMBO reports, 2013
The orphan GluD2 receptor belongs to the ionotropic glutamate receptor family but does not bind glutamate. Ligand-gated GluD2 currents have never been evidenced, and whether GluD2 operates as an ion channel has been a long-standing question. Here, we show that GluD2 gating is triggered by type 1 metabotropic glutamate receptors, both in a heterologous ...

Oligodendrocyte Precursor Cells in Demyelination Repair: Mechanisms, Crosstalk, and Therapeutic Frontiers

Medicine Bulletin, EarlyView.
ABSTRACT In multiple sclerosis (MS), demyelination is often accompanied by severe motor and cognitive disability. Remyelination is the process of regenerating new myelin sheath on impaired axons, which is typically carried out by oligodendrocyte precursor cells (OPCs).

a main role for metabotropic glutamate receptor 1 in the neuroprotective effect of estrogen

Molecular and Cellular Pharmacology, 2012
Estrogen exerts neuroprotective activity under different experimental conditions through classical nuclear receptors, but mainly receptors expressed at the cell surface. Transducing mechanisms activated by these membrane estrogen receptors in the brain have been intensely investigated and, among others, interaction with G-protein coupled, metabotropic ...

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

, 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

Neurochemical Changes in the Mouse Hippocampus Underlying the Antidepressant Effect of Genetic Deletion of P2X7 Receptors. [PDF]

, 2013
Recent investigations have revealed that the genetic deletion of P2X7 receptors (P2rx7) results in an antidepressant phenotype in mice. However, the link between the deficiency of P2rx7 and changes in behavior has not yet been explored.

A comprehensive review on adaptive plasticity and recovery mechanisms post‐acquired brain injury

Neuroprotection, EarlyView.
This figure illustrates the dynamic process of neurogenesis following brain injury, focusing on the roles of neural stem and progenitor cells at the injury site. Key mechanisms include axonal sprouting, synaptogenesis, dendritic remodeling, and brain‐derived neurotrophic factor signaling via TrkB receptors.

The G protein-coupled receptor heterodimer network (GPCR-HetNet) and its hub components [PDF]

, 2014
G protein-coupled receptors (GPCRs) oligomerization has emerged as a vital characteristic of receptor structure. Substantial experimental evidence supports the existence of GPCR-GPCR interactions in a coordinated and cooperative manner.

Exploring the pathophysiology underlying clozapine‐induced enhancement of glutamatergic transmission through L‐glutamate and D‐serine release associated with pannexin1 hemichannels

British Journal of Pharmacology, EarlyView.
Abstract Background and purpose Clozapine, an approved antipsychotic for treatment‐resistant schizophrenia (TRS), enhances glutamatergic transmission by increasing exocytosis and non‐exocytosis glutamate release; however, its full action remained to be clarified.

β‐arrestin dependent signaling of metabotropic glutamate receptor 1

The FASEB Journal, 2013
Metabotropic glutamate 1 (mGlu1) receptor is a G protein‐coupled receptor expressed mainly in the central nervous system. Classically, stimulation of mGlu1 receptors activates Gαq and increases production of the second messengers IP3 and DAG. In addition, our research has demonstrated that mGlu1 receptors activate a distinct, G protein‐independent ...
