A Frank Assessment of SHANK: Impacts of Pathogenic Variations in SHANK3 on Preclinical Models of Phelan McDermid Syndrome

Autism Research, EarlyView.
ABSTRACT Although there are as many as 40 preclinical models of the neurodevelopmental disorder Phelan McDermid syndrome (PMS, or 22q13.3 deletion syndrome), detailed phenotypic analyses to compare the effects of different pathogenic variants and inform treatment design are lacking.

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 ...

Ionotropic glutamate receptors and their implications in cancer and cancer therapeutics

Biomedical and Biotechnology Research Journal, 2021
Glutamine, an excitatory neurotransmitter, is necessary for physiological as well as pathological processes. Other than neuronal disorders and/or cancers, glutamate receptors have also been associated with an array of other malignancies. The metabotropic

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).

Conformational diversity in class C GPCR positive allosteric modulation

Nature Communications
The metabotropic glutamate receptors (mGlus) are class C G protein-coupled receptors (GPCR) that form obligate dimers activated by the major excitatory neurotransmitter L-glutamate.

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.

Pharmacological treatments inhibiting levodopa-induced dyskinesias in MPTP-lesioned monkeys: brain glutamate biochemical correlates

Frontiers in Neurology, 2014
Antiglutamatergic drugs can relieve Parkinson’s disease (PD) symptoms and decrease L-3,4-dihydroxyphenylalanine (L-DOPA)-induced dyskinesias (LID).

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.

Calcium Signaling Pathways Involved in Long-Term Potentiation at Excitatory Synapses on Parvalbumin Positive Fast-Spiking GABAergic Neurons in the Mouse Visual Cortex [PDF]

Cell Journal, 2009
Objective: Recently, we reported the presence of metabotropic glutamate receptor type 5(mGluR-5) dependent long-term potentiation (LTP) at excitatory synapses on fast-spikingGABAergic (FS-GABA) cells in the visual cortex.

Astrocytes Control Neuronal Excitability in the Nucleus Accumbens

The Scientific World Journal, 2007
Though accumulating evidence shows that the metabotropic glutamate receptor 5 (mGluR5) mediates some of the actions of extracellular glutamate after cocaine use, the cellular events underlying this action are poorly understood.
