Pharmacological analysis of ionotropic glutamate receptor function in neuronal circuits of the zebrafish olfactory bulb. [PDF]

PLoS ONE, 2008
Although synaptic functions of ionotropic glutamate receptors in the olfactory bulb have been studied in vitro, their roles in pattern processing in the intact system remain controversial.

KIF1A‐Mediated Axonal Transport of Netrin‐1 in iPSC‐Derived Human Forebrain Neurons

Cytoskeleton, EarlyView.
ABSTRACT Netrin‐1 is a secreted laminin‐like protein that functions as a guidance cue for axon pathfinding in development. Netrin‐1 also modulates synapse formation in developing neurons and long‐term potentiation in mature neurons. Netrin‐1 is expressed in human neurons; however, its intracellular distribution and trafficking have not been assessed ...

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 ...

GRIA2 Variant Associated With Paradoxical Response to Perampanel Expanding the Spectrum of GRIA2‐Related Epileptic Encephalopathy: Case Report and Literature Review

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Introduction GRIA2 encodes the GluA2 ionotropic α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid (AMPA) receptor subunit. Pathogenic GRIA2 variants cause epilepsy, developmental delay, and neurobehavioral disorders. Characterizations of clinical features, including seizure types and their treatments, in patients with GRIA2‐related ...

Do Brain Extracellular Fluid Concentrations Predict PET‐Inferred Receptor Occupancy in Human CNS? A Mechanistic Model‐Based Analysis of Dopamine D2 Receptor Ligands

Clinical Pharmacology &Therapeutics, EarlyView.
A mechanistic CNS PBPK model framework was applied to eight antipsychotic D2 receptor ligands, comparing brain extracellular fluid (brainECF) and brain cell membrane (brainM) as biophase for predicting human receptor occupancy compared against PET neuroimaging data. BrainM concentrations showed improved agreement with PET‐derived receptor occupancy for

Stargazin Modulation of AMPA Receptors [PDF]

, 2016
Fast excitatory synaptic signaling in the mammalian brain is mediated by AMPA-type ionotropic glutamate receptors. In neurons, AMPA receptors co-assemble with auxiliary proteins, such as stargazin, which can markedly alter receptor trafficking and gating.

GRIP1 Binds to ApoER2 and EphrinB2 to Induce Activity-Dependent AMPA Receptor Insertion at the Synapse

Cell Reports, 2017
Regulation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor trafficking in response to neuronal activity is critical for synaptic function and plasticity.

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

Photoinactivation of Native AMPA Receptors Reveals Their Real-Time Trafficking [PDF]

, 2005
SummaryAMPA receptors mediate the majority of the fast excitatory transmission in the central nervous system. Much evidence suggests that the fast trafficking of AMPA receptors into and out of the postsynaptic membrane underlies changes in synaptic ...

Cenobamate use in super‐refractory status epilepticus: A report of three cases

Epileptic Disorders, EarlyView.
Abstract Objectives Super‐refractory status epilepticus (SRSE) is a neurological emergency with high morbidity and mortality. Cenobamate, a novel antiseizure medication, may be helpful in managing SRSE, but evidence is limited. Methods This retrospective case series reports the use of cenobamate as add‐on therapy in the management of three cases of ...
