A consensus roadmap for post‐traumatic epilepsy: Clinical biomarkers, research priorities, policy barriers, and pathways to interventional trials

open access: yesEpilepsia, EarlyView.
Abstract Understanding the mechanisms underlying post‐traumatic epilepsy (PTE) following traumatic brain injury (TBI), and developing strategies to prevent or modify its progression, has been the focus of large collaborative efforts within the epilepsy and TBI research communities for over a decade.

Effects of fenfluramine and sigma‐1‐dependent pharmacological and genetic modulation in a mouse kindling model

open access: yesEpilepsia, EarlyView.
Abstract Objective Sigma‐1 is a chaperone protein that serves as a key homeostatic regulator, implicated in neuronal excitability and seizure control. Positive allosteric modulators offer a use‐dependent means to enhance Sigma‐1 activity, potentially with favorable tolerability compared to direct agonists.

Quantal release of glutamate generates pure kainate and mixed AMPA/kainate EPSCs in hippocampal neurons.

open access: yes, 2002
International audienceThe relative contribution of kainate receptors to ongoing glutamatergic activity is at present unknown. We report the presence of spontaneous, miniature, and minimal stimulation-evoked excitatory postsynaptic currents (EPSCs) that ...

Parkinson’s disease, epilepsy, and amyotrophic lateral sclerosis—emerging role of AMPA and kainate subtypes of ionotropic glutamate receptors

open access: yesFrontiers in Cell and Developmental Biology, 2023
Ionotropic glutamate receptors (iGluRs) mediate the majority of excitatory neurotransmission and are implicated in various neurological disorders. In this review, we discuss the role of the two fastest iGluRs subtypes, namely, α-amino-3-hydroxy-5-methyl ...

Unique deficits in place coding across subfields of the hippocampus in a mouse model of temporal lobe epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Memory problems are comorbid with temporal lobe epilepsy (TLE). Animal models of TLE reveal impairments in spatial firing fields of hippocampal place cells, providing a potential neural substrate for memory problems. Each subfield of the hippocampus carries out unique aspects of spatial memory, yet little is known about how ...

Ripple‐related firing of identified deep CA1 pyramidal cells in chronic temporal lobe epilepsy in mice

open access: yesEpilepsia Open, 2019
Summary Objective Temporal lobe epilepsy (TLE) is often associated with memory deficits. Reactivation of memory traces in the hippocampus occurs during sharp‐wave ripples (SWRs; 140‐250 Hz).

Status Epilepticus: Behavioral and Electroencephalography Seizure Correlates in Kainate Experimental Models

open access: yesFrontiers in Neurology, 2018
Various etiological factors, such as head injury, chemical intoxication, tumors, and gene mutation, can induce epileptogenesis. In animal models, status epilepticus (SE) triggers epileptogenesis.

Modeling temporal lobe epilepsy with hippocampal sclerosis in rats using the selective neurotoxin stable substance P‐saporin

open access: yesEpilepsia, EarlyView.
On day 0 adult male and female rats were injected with Stable Substance P‐Saporin (SSP‐SAP) at 4 unilateral sites along the longitudinal axis of the dentate gyrus. Rats exhibited spontaneous electrographic and behavioral reactive seizures between days 4‐6. There was a progressive loss of CA1 and CA3 neurons and a progressive increase in astrocytes over

Structure of a High-Affinity Kainate Receptor: GluK4 Ligand-Binding Domain Crystallized with Kainate

open access: yes, 2016
Ionotropic glutamate receptors play a key role for fast neurotransmission in the central nervous system and have been linked to several neurological diseases and disorders.

The prostaglandin EP1 receptor potentiates kainate receptor activation via a protein kinase C pathway and exacerbates status epilepticus

open access: yesNeurobiology of Disease, 2014
Prostaglandin E2 (PGE2) regulates membrane excitability, synaptic transmission, plasticity, and neuronal survival. The consequences of PGE2 release following seizures has been the subject of much study.
