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 ...

The multiple hit model of infantile and epileptic spasms: The 2025 update

Epilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.

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 ...

Neonatal seizures and GABAergic drugs: Scylla and Charybdis?

Epilepsia Open, EarlyView.
Abstract Neonates have a high incidence of seizures that are frequently difficult to control with conventional first‐line anti‐seizure medications, which are gamma‐aminobutyric acid (GABA) agonists. The reasons for this clinical problem are multifold but are likely related to the unique physiology of the immature nervous system. Specifically, the early

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

Impact of cenobamate on cortical responses to transcranial magnetic stimulation in people with drug‐resistant focal epilepsy

Epilepsia Open, EarlyView.
Abstract Objective Cenobamate (CNB) is an effective antiseizure medication, though its mechanisms of efficacy remain incompletely understood. We assessed changes in cortical responses to transcranial magnetic stimulation (TMS) following CNB treatment.

Kainate receptor function in rodent subcortical visual processing.

, 2007
Glutamate is found throughout the central nervous system and has been shown to be an important excitatory neurotransmitter in the visual system. There are two subdivisions of receptor on which this ubiquitous neurotransmitter acts, metabotropic (mGluR ...

Perampanel as add‐on in high‐grade glioma–related epilepsy: Seizure control and QoL in a prospective, multicenter, real‐world 6‐month follow‐up study

Epilepsia Open, EarlyView.
Abstract Objective High‐grade astrocytomas, including glioblastomas, are aggressive brain tumors with poor prognosis and a 5‐year survival below 7%. Seizures affect up to 75% of glioma patients, especially in low‐grade tumors but also in high‐grade cases.

Preferential assembly of heteromeric kainate and AMPA receptor amino terminal domains

eLife, 2017
Ion conductivity and the gating characteristics of tetrameric glutamate receptor ion channels are determined by their subunit composition. Competitive homo- and hetero-dimerization of their amino-terminal domains (ATDs) is a key step controlling assembly.
