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.

Involvement of hippocampal AMPA glutamate receptor changes and the cAMP/protein kinase A/CREB-P signalling pathway in memory consolidation of an avoidance task in rats

Brazilian Journal of Medical and Biological Research, 1997
Training in step-down inhibitory avoidance (0.3-mA footshock) is followed by biochemical changes in rat hippocampus that strongly suggest an involvement of quantitative changes in glutamate AMPA receptors, followed by changes in the dopamine D1 receptor ...

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).

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 ...

GluA2-lacking AMPA receptors in hippocampal CA1 cell synapses: evidence from gene-targeted mice

Frontiers in Molecular Neuroscience, 2012
The GluA2 subunit in heteromeric AMPA receptor channels restricts Ca2+ permeability and block by polyamines, rendering linear the current-voltage relationship of these glutamate-gated cation channels.

P2X7 receptors exert a permissive effect on the activation of presynaptic AMPA receptors in rat trigeminal caudal nucleus glutamatergic nerve terminals

The Journal of Headache and Pain, 2020
Background Purine receptors play roles in peripheral and central sensitization and are associated with migraine headache. We investigated the possibility that ATP plays a permissive role in the activation of AMPA receptors thus inducing Glu release from ...

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

Stargazin and AMPA receptor membrane expression is increased in the somatosensory cortex of Genetic Absence Epilepsy Rats from Strasbourg

Neurobiology of Disease, 2011
Absence-like seizures in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model are believed to arise in hyperexcitable somatosensory cortical neurons, however the cellular basis of this increased excitability remains unknown. We have previously

Medial prefrontal cortex neuronal activation and synaptic alterations after stress-induced reinstatement of palatable food seeking: a study using c-fos-GFP transgenic female rats [PDF]

, 2012
Relapse to maladaptive eating habits during dieting is often provoked by stress and there is evidence for a role of ovarian hormones in stress responses and feeding.

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)
