The Differing Phenotypes of the Three Most Common Postsynaptic Congenital Myasthenic Syndromes Governed by Their Underlying Molecular Pathogenic Mechanisms

Muscle &Nerve, EarlyView.
ABSTRACT The congenital myasthenic syndromes are rare disorders of impaired signal transmission at the neuromuscular junction. Despite next generation sequencing facilitating the identification of variants in myasthenic‐associated genes, these variants are frequently of unknown significance and the clinical diagnosis can be delayed.

Extrasynaptic vesicle recycling in mature hippocampal neurons [PDF]

Nature Communications, 2011
Fast neuronal signalling relies on highly regulated vesicle fusion and recycling at specialized presynaptic terminals. Recently, examples of non-classical neurotransmission have also been reported, where fusion of vesicles can occur at sites remote from conventional synapses.

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABAA Receptors That Modulate Dorsal Root Ganglia Neuron Excitability

Glia, Volume 74, Issue 9, September 2026.
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.

BDNF Reduces Toxic Extrasynaptic NMDA Receptor Signaling via Synaptic NMDA Receptors and Nuclear-Calcium-Induced Transcription of inhba/Activin A

Cell Reports, 2015
The health of neurons is critically dependent on the relative signaling intensities of survival-promoting synaptic and death-inducing extrasynaptic NMDA receptors.

The serine hydrolase ABHD6 controls survival and thermally induced seizures in a mouse model of Dravet syndrome

Neurobiology of Disease, 2023
Evidence suggests that inhibition of α/β hydrolase-domain containing 6 (ABHD6) reduces seizures; however, the molecular mechanism of this therapeutic response remains unknown.

A TREK‐1/AQP4/TRPA1/BDNF Signaling Axis Is Associated With Astrocytic Volume Transients, Synaptic Plasticity, and Spatial Memory

Glia, Volume 74, Issue 9, September 2026.
Astrocytic TREK‐1‐dependent volume transients contribute to hippocampal synaptic plasticity and memory formation. TRPA1‐mediated astrocytic calcium signaling is required for long‐term potentiation, while astrocytic BDNF is necessary and sufficient to support sustained synaptic plasticity.

Presynaptic and extrasynaptic regulation of posterior nucleus of thalamus [PDF]

Journal of Neurophysiology, 2017
The posterior nucleus of thalamus (PO) is a higher-order nucleus involved in sensorimotor processing, including nociception. An important characteristic of PO is its wide range of activity profiles that vary across states of arousal, thought to underlie differences in somatosensory perception subject to attention and degree of consciousness ...

Loss-of-consciousness: sources of GABAergic input to the mesopontine tegmental anesthesia area

Frontiers in Neuroscience
Exposure of neurons in the brainstem mesopontine tegmental anesthesia area (MPTA) to minute quantities of GABAergic general anesthetics at clinically relevant concentrations is sufficient to induce loss-of-consciousness (LOC), while lesioning this ...

Organization of Astrocytic GLT‐1 at Cortical Inhibitory Synapses

Glia, Volume 74, Issue 8, August 2026.
GLT‐1+ ALs frequently juxtapose symmetric synapses. Distance‐based phenotyping identifies symmetric‐ and asymmetric‐associated GLT‐1+ ALs. Distal inhibitory synapses show enriched GLT‐1/α2 couples in ALs within 1000 nm, conserved in human cortex. ABSTRACT Glutamate spillover from excitatory synapses modulates neighboring inhibitory synapses, yet the ...

Super-resolution imaging of synaptic and Extra-synaptic AMPA receptors with different-sized fluorescent probes

eLife, 2017
Previous studies tracking AMPA receptor (AMPAR) diffusion at synapses observed a large mobile extrasynaptic AMPAR pool. Using super-resolution microscopy, we examined how fluorophore size and photostability affected AMPAR trafficking outside of, and ...
