Genome‐Wide Insights and Polygenic Risk Scores in Common Epilepsies: A Narrative Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT The research of single gene‐related disorders or pathogenic copy‐number variations (CNVs) has given a significant impetus to the shift from a diagnostic work‐up focused on epileptic syndromes to genomic approaches in individuals with severe pediatric‐onset epilepsies and in developmental and epileptic encephalopathies.

Shedding Light on Metabotropic Glutamate Receptors [PDF]

Cell Chemical Biology, 2016
In this issue of Cell Chemical Biology, the elegant manuscript by Rovira et al. (2016) describes a negative allosteric modulator (NAM) of mGlu4 metabotropic glutamate receptors with in vivo activity. This compound is rapidly and reversibly inactivated by light and represents a powerful pharmacological tool for the study of mGlu4 receptors in their ...

Differential Presynaptic Localization of Metabotropic Glutamate Receptor Subtypes in the Rat Hippocampus

Journal of Neuroscience, 1997
Neurotransmission in the hippocampus is modulated variously through presynaptic metabotropic glutamate receptors (mGluRs). To establish the precise localization of presynaptic mGluRs in the rat hippocampus, we used subtype-specific antibodies for eight ...

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.

Membrane Topology of a Metabotropic Glutamate Receptor [PDF]

Journal of Biological Chemistry, 2003
The metabotropic glutamate receptors (mGluRs) have been predicted to have a classical seven transmembrane domain structure similar to that seen for members of the G-protein-coupled receptor (GPCR) superfamily. However, the mGluRs (and other members of the family C GPCRs) show no sequence homology to the rhodopsin-like GPCRs, for which this seven ...

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 ...

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).

Metabotropic glutamate receptor agonists for schizophrenia [PDF]

British Journal of Psychiatry, 2008
SummaryA drug acting at metabotropic glutamate receptors has recently been reported to be an effective antipsychotic, breaking the rule that only dopamine receptor-blocking drugs have this property. The finding complements accumulating evidence that glutamatergic abnormalities are important in the pathophysiology of schizophrenia.

Activation requirements for metabotropic glutamate receptors [PDF]

Neuroscience Letters, 2013
It has been common experimentally to use high frequency, tetanic, stimulation to activate metabotropic glutamate receptors (mGluRs) in cortex and thalamus. To determine what type of stimulation is actually necessary to activate mGluRs we examined the effects of varying stimulation duration and intensity on activating mGluR responses.

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.
