Activity- and sleep-dependent regulation of tonic inhibition by Shisa7 [PDF]

open access: yesCell Reports, 2021
Summary: Tonic inhibition mediated by extrasynaptic γ-aminobutyric acid type A receptors (GABAARs) critically regulates neuronal excitability and brain function. However, the mechanisms regulating tonic inhibition remain poorly understood.

GABAAR-mediated tonic inhibition differentially modulates intrinsic excitability of VIP- and SST- expressing interneurons in layers 2/3 of the somatosensory cortex [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2023
Extrasynaptic GABAA receptors (GABAARs) mediating tonic inhibition are thought to play an important role in the regulation of neuronal excitability. However, little is known about a cell type-specific tonic inhibition in molecularly distinctive types of ...

Bidirectional plasticity of GABAergic tonic inhibition in hippocampal somatostatin- and parvalbumin-containing interneurons [PDF]

open access: yesFrontiers in Cellular Neuroscience, 2023
GABAA receptors present in extrasynaptic areas mediate tonic inhibition in hippocampal neurons regulating the performance of neural networks. In this study, we investigated the effect of NMDA-induced plasticity on tonic inhibition in somatostatin- and ...

Suppressing astrocytic GABA transaminase enhances tonic inhibition and weakens hippocampal spatial memory [PDF]

open access: yesExperimental and Molecular Medicine
Pharmacological suppression of γ-aminobutyric acid (GABA) transaminase (GABA-T), the sole GABA-degrading enzyme and a potential therapeutic target for treating brain disorders such as epilepsy, increases not only phasic inhibition but also tonic ...

Alzheimer’s Disease Enhanced Tonic Inhibition is Correlated With Upregulated Astrocyte GABA Transporter-3/4 in a Knock-In APP Mouse Model [PDF]

open access: yesFrontiers in Pharmacology, 2022
Cognitive decline is a major symptom in Alzheimer’s disease (AD), which is strongly associated with synaptic excitatory-inhibitory imbalance. Here, we investigated whether astrocyte-specific GABA transporter 3/4 (GAT3/4) is altered in APP knock-in mouse ...

Cerebellar tonic inhibition orchestrates the maturation of information processing and motor coordination [PDF]

open access: yesExperimental and Molecular Medicine
Tonic inhibition in cerebellar granule cells is crucial for maintaining information coding fidelity during motor coordination. It arises through both activity-dependent and activity-independent mechanisms, and the interplay between these mechanisms ...

Chronic Stress Oppositely Regulates Tonic Inhibition in Thy1-Expressing and Non-expressing Neurons in Amygdala [PDF]

open access: yesFrontiers in Neuroscience, 2020
Chronic or prolonged exposure to stress ranks among the most important socioenvironmental factors contributing to the development of neuropsychiatric diseases, a process generally associated with loss of inhibitory tone in amygdala.

The impact of tonic GABAA receptor-mediated inhibition on neuronal excitability varies across brain region and cell type

open access: yesFrontiers in Neural Circuits, 2014
The diversity of GABAA receptor (GABAAR) subunits and the numerous configurations during subunit assembly give rise to a variety of receptors with different functional properties. This heterogeneity results in variations in GABAergic conductances across

Subunit-specific mechanisms of isoflurane-induced acute tonic inhibition in dentate gyrus granule neuron [PDF]

open access: yesExperimental Biology and Medicine
Prolonged exposure to volatile anesthetics may raise the risk of developing cognitive impairment by acting on gamma-a Aminobutyric acid A receptors (GABAAR). The dentate gyrus plays an important role in the hippocampus and has a high potential for neural

Receptors with low affinity for neurosteroids and GABA contribute to tonic inhibition of granule cells in epileptic animals

open access: yesNeurobiology of Disease, 2010
Neurosteroid sensitivity of GABAA receptor mediated inhibition of the hippocampal dentate granule cells (DGCs) is reduced in animal models of temporal lobe epilepsy.
