Fast detection of extrasynaptic GABA with a whole-cell sniffer

Frontiers in Cellular Neuroscience, 2014
Gamma-amino-butyric acid (GABA) is the main inhibitory transmitter of the brain. It operates by binding to specific receptors located both inside and outside synapses.

Extrasynaptic CaMKIIα is involved in the antidepressant effects of ketamine by downregulating GluN2B receptors in an LPS-induced depression model

Journal of Neuroinflammation, 2020
Background A subanesthetic dose of ketamine provides rapid and effective antidepressant effects, but the molecular mechanism remains elusive. It has been reported that overactivation of extrasynaptic GluN2B receptors is associated with the antidepressant

WONOEP appraisal: Biomarkers and treatment strategies beyond the synapse

Epilepsia, EarlyView.
Abstract Epilepsy is a heterogeneous neurological disorder affecting more than 70 million people worldwide, posing significant challenges for clinicians due to its complex etiology, diverse manifestations, variable treatment responses, and the inability to predict seizures or disease onset reliably.

Thermodynamic Efficiency of Somatic Exocytosis of Serotonin

Frontiers in Physiology, 2019
Through somatic exocytosis neurons liberate immense amounts of transmitter molecules that modulate the functioning of the nervous system. A stream of action potentials triggers an ATP-dependent transport of transmitter-containing vesicles to the plasma ...

The Disruption of NMDAR/TRPM4 Death Signaling with TwinF Interface Inhibitors: A New Pharmacological Principle for Neuroprotection

Pharmaceuticals, 2023
With the discovery that the acquisition of toxic features by extrasynaptic NMDA receptors (NMDARs) involves their physical interaction with the non-selective cation channel, TRPM4, it has become possible to develop a new pharmacological principle for ...

Absence seizures: Update on signaling mechanisms and networks

Epilepsia 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 ...

Extrasynaptic Neurotransmission as a Way of Modulating Neuronal Functions [PDF]

Frontiers in Physiology, 2012
Extrasynaptic neurotransmission allows neuronal communication at variable distances, based on the release and diffusion of chemical substances from the soma, axon, or dendrites of neurons, or after transmitter leak-out from the synaptic cleft (De-Miguel and Trueta, 2005; Fuxe et al., 2007).

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Tannic Acid Mitigates Monosodium Glutamate‐Induced Cortical Damage by Modulating Synaptic and Calcium‐Related Gene and Protein Expression

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neurotoxicity induced by excessive glutamatergic signaling is associated with synaptic dysfunction, calcium imbalance, and oxidative stress, which are key molecular events implicated in several neurodegenerative conditions. Monosodium glutamate (MSG), a common flavor enhancer, may exert neurotoxic effects, particularly on synaptic integrity ...

Local Chemical Gradients in a Mammalian Cortex Measured In Vivo With a Silicon Nanodialysis Mass Spectrometry Platform

Angewandte Chemie, Volume 138, Issue 26, 22 June 2026.
Fluorescence image of the coronal slice of mouse brain where multiple neurochemicals have been measured in vivo with a nanodialysis platform coupled to CE‐MS to reveal strong millimeter‐scale spatial chemical gradients. Formation and maintenance of such local chemical compartments in the otherwise diffusion‐homogeneous cortex indicates strong ...
