Synaptic ultrastructural alterations in human focal cortical dysplasia: Insights from volume electron microscopy

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a developmental malformation of the cerebral cortex and a leading cause of drug‐resistant epilepsy in children and young adults. Disruption of the excitation–inhibition (E–I) balance is a hallmark of neuronal hyperexcitability in FCD, yet the underlying synaptic ultrastructural changes remain poorly ...

Potassium–chloride cotransporter 2 activity dampens induced ictal‐like activity in neocortical slices containing the seizure propagation zone of temporal lobe epilepsy patients

Epilepsia, EarlyView.
The K⁺/Cl− cotransporter (KCC2) limits induced ictal‐like events and their spread in the supragranular layer of human neocortical slices from the seizure‐propagation zone of temporal lobe epilepsy patients. Cl⁻ extrusion is present in supragranular pyramidal neurons but limited under high somatic Cl⁻ load.

C1q neutralization during epileptogenesis attenuates complement‐mediated synaptic elimination and epileptiform activity

Epilepsia, EarlyView.
Abstract Objective Accumulating evidence indicates that aberrant C1q‐C3 complement signaling in microglia and astrocytes drives synaptic dysfunction and neuronal loss. C1q‐mediated synaptic dysfunction disrupts neuronal circuitry balance and can lead to network hyperexcitability in epilepsy.

Zebrafish models of developmental epileptic encephalopathy accurately reflect clinical electrographic biomarkers

Epilepsia, EarlyView.
Abstract Objective Developmental epileptic encephalopathies (DEEs) are epilepsy conditions characterized by significant severity and treatment challenges. Spectral components of the encephalogram (EEG) may provide a valuable biomarker of epileptic severity.

Type I interferon signalling and interferon‐responsive microglia in health and disease

The FEBS Journal, EarlyView.
Recent insights reveal that type I interferon (IFN‐I) signalling plays critical roles in the nervous system beyond antiviral defence. Dysregulated IFN‐I activity is increasingly linked to neurological dysfunction and neurodegeneration, with microglia as central mediators. This review explores the broader impact of IFN‐I signalling on the nervous system
