Re-Evaluation of the Ultrastructural Localization of Tonic GABA-A Receptors

Pharmaceuticals
Cell membrane receptors play key roles in physiological and pathological processes, yet the mechanisms governing their expression and distribution across the plasma membrane remain not completely understood. Broadly, membrane receptors can be categorized

Relationship between tonic inhibitory currents and phasic inhibitory activity in the spinal cord lamina II region of adult mice

Molecular Pain, 2006
Phasic and tonic inhibitions are two types of inhibitory activities involved in inhibitory processing in the CNS. In the spinal cord dorsal horn, phasic inhibition is mediated by both GABAergic and glycinergic inhibitory postsynaptic currents.

Extrasynaptic α6 subunit-containing GABAA receptors modulate excitability in turtle spinal motoneurons.

PLoS ONE, 2014
Motoneurons are furnished with a vast repertoire of ionotropic and metabotropic receptors as well as ion channels responsible for maintaining the resting membrane potential and involved in the regulation of the mechanisms underlying its membrane ...

Control of hippocampal gamma oscillation frequency by tonic inhibition and excitation of interneurons. [PDF]

, 2010
Gamma-frequency oscillations depend on phasic synaptic GABA(A) receptor (GABA(A)R)-mediated inhibition to synchronize spike timing. The spillover of synaptically released GABA can also activate extrasynaptic GABA(A)Rs, and such tonic inhibition may also ...

Cortical Tonic Inhibition Gates the Expression of Spike-and-Wave Discharges Associated with Absence Epilepsy

Journal of Integrative Neuroscience
Objective: Absence seizures result from aberrant thalamocortical processing that confers synchronous, bilateral spike-and-wave discharges (SWDs) and behavioral arrest.

Astrocytic GABA Accumulation in Experimental Temporal Lobe Epilepsy

Frontiers in Neurology, 2020
An imbalance of excitation and inhibition has been associated with the pathophysiology of epilepsy. Loss of GABAergic interneurons and/or synaptic inhibition has been shown in various epilepsy models and in human epilepsy.

The adjustment of γ-aminobutyric acidA tonic subunits in Huntington's disease: from transcription to translation to synaptic levels into the neostriatum

Neural Regeneration Research, 2018
γ-Aminobutyric acid (GABA), plays a key role in all stages of life, also is considered the main inhibitory neurotransmitter. GABA activates two kind of membrane receptors known as GABAA and GABAB, the first one is responsible to render tonic inhibition ...

Multiple and plastic receptors mediate tonic GABAA receptor currents in the hippocampus [PDF]

, 2005
Persistent activation of GABAA receptors by extracellular GABA (tonic inhibition) plays a critical role in signal processing and network excitability in the brain.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
