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).

ARC Expands the DAAM1 Microexon‐Mediated Actin–RHOA/ROCK Interplay

Cytoskeleton, EarlyView.
ABSTRACT Actin cytoskeleton and its dynamics play a crucial role in synaptic function, influencing dendritic spines' structural and functional plasticity. Recent findings unveiled the significance of alternative splicing of a neural‐specific microexon in DAAM1 in modulating actin's role in synaptic processes.

Differential modulation of NMDA and AMPA receptors by cellular prion protein and copper ions

Molecular Brain, 2018
N-Methyl-D-aspartate receptors (NMDARs) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) are two major types of ionotropic glutamate receptors involved in synaptic transmission.

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 ...

Downregulation of GluA2 AMPA receptor subunits reduces the dendritic arborization of developing spinal motoneurons. [PDF]

PLoS ONE, 2012
AMPA receptors lacking the GluA2 subunit allow a significant influx of Ca(2+) ions. Although Ca(2+)-permeable AMPA receptors are a familiar feature at early stages of development, the functional significance of these receptors during the maturation of ...

Neuronal surface and intracellular antibody testing in patients with long‐term epilepsy

Epilepsia Open, EarlyView.
Abstract Objective We aimed to investigate the frequency of neuronal surface and intracellular antibodies in individuals with long‐term epilepsy and the associated clinical and laboratory characteristics. Methods We tested sera from 223 patients with epilepsy without signs of autoimmune encephalitis and 12 patients with epilepsy and a subacute onset of

Auxiliary Subunits: Shepherding AMPA Receptors to the Plasma Membrane

Membranes, 2014
Ionotropic glutamate receptors (iGluRs) are tetrameric ligand-gated cation channels that mediate excitatory signal transmission in the central nervous system (CNS) of vertebrates.

Effectiveness of perampanel as the only adjunctive anti‐seizure medication in adults: Final results from the observational PERPRISE study in Germany

Epilepsia Open, EarlyView.
Abstract Objective The PERPRISE study (Study 509; NCT04202159) was a prospective, observational, non‐interventional study in a real‐world setting in Germany. This study was conducted to evaluate the effectiveness of perampanel as the only adjunctive treatment for 12 months in patients aged ≥18 years with focal to bilateral tonic–clonic seizures (FBTCS)

The role of AMPA receptors in postsynaptic mechanisms of synaptic plasticity

Frontiers in Cellular Neuroscience, 2014
In the mammalian central nervous system, excitatory glutamatergic synapses harness neurotransmission that is mediated by ion flow through α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs).

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

Environmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...
