AMPA receptor subunit expression in the endoplasmic reticulum in frontal cortex of elderly patients with schizophrenia. [PDF]

PLoS ONE, 2012
Several lines of evidence indicate altered trafficking of α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA) receptors in schizophrenia. Previous reports have shown potential changes in the trafficking of AMPA receptors based on subunit expression

Real‐world use of adjunctive perampanel for focal‐onset seizures in Italy: A mirroring clinical practice study of perampanel in adults and adolescents (AMPA)

Epilepsia Open, EarlyView.
Abstract Objective The AMPA study (Study 501; NCT04257604) was a multicenter, prospective, 12‐month observational study in Italy that evaluated the effectiveness and safety of adjunctive perampanel in patients with focal‐onset seizures (FOS), with or without focal to bilateral tonic–clonic seizures (FBTCS).

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 ...

Desensitization dynamics of the AMPA receptor

Structure, 2023
To perform their physiological functions, amino methyl propionic acid receptors (AMPARs) cycle through active, resting, and desensitized states, and dysfunction in AMPAR activity is associated with various neurological disorders. Transitions among AMPAR functional states, however, are largely uncharacterized at atomic resolution and are difficult to ...

Stargazin Dephosphorylation Mediates Homeostatic Synaptic Downscaling of Excitatory Synapses

Frontiers in Molecular Neuroscience, 2018
Synaptic scaling is a form of homeostatic plasticity that is critical for maintaining neuronal activity within a dynamic range, and which alters synaptic strength through changes in postsynaptic AMPA-type glutamate receptors.

Calcineurin Mediates Synaptic Scaling Via Synaptic Trafficking of Ca2+-Permeable AMPA Receptors

PLoS Biology, 2014
Kim and Ziff examine the molecular mechanism of synaptic scaling, showing that inhibition of neuronal excitability reduces calcium influx into neurons, resulting in decreased calcineurin activity.

Perampanel as a second‐line therapy to midazolam reduces soman‐induced status epilepticus and neurodegeneration in rats

Epilepsia Open, EarlyView.
Abstract Objective A benzodiazepine (diazepam or midazolam) is one of the current standards of care therapies to effectively terminate organophosphorus nerve agent‐induced status epilepticus when administered shortly after onset. Preclinical studies showed that benzodiazepines were less effective in stopping status epilepticus when treatment was ...

Intracellular machinery for the transport of AMPA receptors [PDF]

British Journal of Pharmacology, 2008
AMPA‐type glutamate receptors are one of the most dynamic components of excitatory synapses. Their regulated addition and removal from synapses leads to long‐lasting forms of synaptic plasticity, known as long‐term potentiation (LTP) and long‐term depression (LTD).

Assembly and Stoichiometry of the AMPA Receptor and Transmembrane AMPA Receptor Regulatory Protein Complex [PDF]

The Journal of Neuroscience, 2010
Glutamate is a major excitatory neurotransmitter in the vertebrate brain. AMPA-type glutamate receptors mediate fast excitatory transmission. AMPA receptors assemble with transmembrane AMPA receptor regulatory protein (TARP) auxiliary subunits and function as native ion channels.

The essential role of AMPA receptor GluR2 subunit RNA editing in the normal and diseased brain

Frontiers in Molecular Neuroscience, 2012
AMPA receptors are comprised of different combinations of GluR1-GluR4 (also known as GluA1-GluA4 and GluR-A to GluR-D) subunits. The GluR2 subunit is subject to Q/R site RNA editing by the ADAR2 enzyme, which converts a codon for glutamine (Q), present ...
