CaMKIIβ insufficiency disrupts cortical networks, producing aberrant low‐gamma oscillations and seizure susceptibility

open access: yesEpilepsia, EarlyView.
Abstract Objective Pathogenic variants in the calcium/calmodulin‐dependent protein kinase II B gene (CAMK2B) have been associated with neurodevelopmental disorders, including epilepsy, yet the mechanisms underlying cortical dysfunction remain largely unclear.

Functional domains of GABAA receptors

open access: yesTrends in Pharmacological Sciences, 1995
The transmitter-gated ion channels mediate rapid synaptic transmission, for example, at the neuromuscular junction using acetylcholine and in the CNS using primarily the amino acids glutamate and GABA. GABAA-receptor Cl- channels share sequence homology with a superfamily of these channels including nicotinic acetylcholine receptor and inhibitory ...

Compound heterozygous SLC12A5 variants expand the molecular and functional spectrum of KCC2‐developmental and epileptic encephalopathy

open access: yesEpilepsia, EarlyView.
Overview of the multimodal experimental approach integrating clinical, genetic, in silico, and in vitro investigations. Clinical: Representative EEG recording setup and ictal traces from affected patients. Genetic: Pedigrees for Families A and B highlighting the inheritance of the four identified SLC12A5 variants (A1, A2, B1, B2).

Add‐on treatment with vinpocetine reduces seizure frequency and improves comorbidities in patients with loss‐of‐function γ‐aminobutyric acid type A receptor variants

open access: yesEpilepsia, EarlyView.
Abstract Objective The semisynthetic compound vinpocetine has gained attention as a potential precision medicine for developmental and epileptic encephalopathies caused by loss‐of‐function (LoF) variants in γ‐aminobutyric acid type A (GABAA) receptor genes. As a positive allosteric modulator of GABAA receptors, case reports suggest that vinpocetine can

Genetic epilepsies with myoclonic seizures: Mechanisms and syndromes

open access: yesEpilepsia Open, EarlyView.
Abstract Genetic epilepsy with myoclonic seizures encompasses a heterogeneous spectrum of conditions, ranging from benign and self‐limiting forms to severe, progressive disorders. While their causes are diverse, a significant proportion stems from genetic abnormalities.

Involvement of GABAA Receptors in the Neuroprotective Effect of Theanine on Focal Cerebral Ischemia in Mice

open access: yesJournal of Pharmacological Sciences, 2007
We investigated the involvement of γ-aminobutyric acidA (GABAA) receptors in the neuroprotective effect of γ-glutamylethylamide (theanine), a component of Japanese green tea, following a 4-h middle cerebral artery (MCA) occlusion in mice.

New insights into epileptic spasm generation and treatment from the TTX animal model

open access: yesEpilepsia Open, EarlyView.
Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.

Absence seizures: Update on signaling mechanisms and networks

open access: yesEpilepsia 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 ...

GABAergic function in the lateral hypothalamus regulates feeding behavior: Possible mediation via orexin

open access: yesNeuropsychopharmacology Reports, 2019
Aim The lateral hypothalamus (LH) is known as the hunger center, but the mechanisms through which the LH regulates food intake are unclear. Since GABA neurons are reported to project to the LH, the present study investigated the role of GABAergic ...
