WONOEP XVII appraisal: The role of the extracellular matrix in epilepsy

Epilepsia, EarlyView.
Abstract The extracellular matrix (ECM) is composed of proteoglycans and glycoproteins that regulate the external environment surrounding neurons, glia, and the vascular system. The ECM is vital for maintaining the structure and function of the brain and also acts as a reservoir for various signaling molecules and neurotransmitters, modulating synaptic

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

Epilepsia, 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

Compensatory rearrangement of parvalbumin interneuron voltage‐gated sodium channel subunits in a mouse model of Dravet syndrome

Epilepsia, EarlyView.
Abstract Heterozygous loss‐of‐function variants in the gene SCN1A, which encodes the voltage‐gated sodium channel (VGSC) pore‐forming (α) subunit NaV1.1, lead to a spectrum of neurological disease, including Dravet syndrome. NaV1.1 is prominently expressed at the proximal portion of the axon initial segment (AIS) of fast‐spiking γ‐aminobutyric ...

Optogenetic Hyperpolarization of Cardiomyocytes Terminates Ventricular Arrhythmia

Frontiers in Physiology, 2019
Cardiac defibrillation to terminate lethal ventricular arrhythmia (VA) is currently performed by applying high energy electrical shocks. In cardiac tissue, electrical shocks induce simultaneously de- and hyperpolarized areas and only depolarized areas ...

Progress report on new epilepsy treatments: A summary of the Eighteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVIII). I. Treatments in preclinical and early clinical development

Epilepsia, EarlyView.
Abstract Over the last 34 years, the Eilat Conference on New Antiepileptic Drugs and Devices has provided an interactive forum for stakeholders to discuss investigational and recently licensed treatments for seizures and epilepsy. The Eighteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVIII) took place in Madrid, Spain, on May 3 ...

Anterior cingulate cortex neuron subtypes differentially regulate seizures

Epilepsia, EarlyView.
Abstract Objective This study aimed to investigate the regulatory roles of distinct neuronal subtypes within the anterior cingulate cortex (ACC) in acute seizures and to identify cell type‐specific mechanisms underlying seizure modulation in this region. Methods Acute seizure models were established in mice via pentylenetetrazol injection.

Epilepsy‐associated SCN2A‐L1342P mutation drives network hyperexcitability and widespread transcriptomic changes in human cortical organoids

Epilepsia, EarlyView.
Abstract Objective SCN2A pathogenic mutations, such as the recurrent heterozygous Nav1.2‐L1342P, are monogenic causes of epilepsy. In this human‐induced pluripotent stem cell–derived model system, we aim to investigate the molecular and cellular mechanisms underlying SCN2A‐L1342P‐associated pathology. Methods Using a human male induced pluripotent stem
