In intact islets interstitial GABA activates GABA(A) receptors that generate tonic currents in α-cells. [PDF]

PLoS ONE, 2013
In the rat islets γ-aminobutyric acid (GABA) is produced by the β-cells and, at least, the α-cells express the GABA(A) receptors (GABA(A) channels). In this study, we examined in intact islets if the interstitial GABA activated the GABA(A) receptors.

Parvalbumin Interneuron‐Dependent Hippocampal Neurogenesis Evoked by Prolonged Rhythmic Light Flicker

Advanced Science, EarlyView.
This study demonstrates that prolonged rhythmic 40 Hz light flicker enhances spatial learning by stimulating PV interneuron‐dependent neurogenesis. The light flicker selectively activates PV interneurons, which enhances GABAergic support for the integration of immature neurons in the adult dentate gyrus.

Oxytocin Reduces Subjective Fear in Naturalistic Social Contexts via Enhancing Top‐Down Middle Cingulate Amygdala Regulation and Brain‐Wide Fear Representations

Advanced Science, EarlyView.
This double‐blind, placebo‐controlled study demonstrates that intranasal oxytocin reduces subjective fear in immersive, naturalistic social (but not non‐social) contexts. Concomitant fMRI reveals that oxytocin enhances middle cingulate activity and amygdala connectivity while it modulates network‐level connectivity and attenuates reactivity of a brain ...

Ethanol activation of protein kinase A regulates GABA-A receptor subunit expression in the cerebral cortex and contributes to ethanol-induced hypnosis

Frontiers in Neuroscience, 2012
Protein kinases are implicated in neuronal cell functions such as modulation of ion channel function, trafficking and synaptic excitability. Both protein kinase C (PKC) and A (PKA) are involved in regulation of γ-aminobutyric acid type A (GABA-A ...

Activation of Spinal Astrocyte α2A Adrenoceptors Protects Against Sepsis‐Induced Heart Injury Through Inhibition of GABAergic Neuronal Necroptosis

Advanced Science, EarlyView.
The study in this paper found that activating the α2A receptors of astrocytes in the thoracic spinal cord can reduce the release of inflammatory factors, thereby decreasing the necroptosis of GABAergic neurons and consequently alleviating myocardial injury caused by sepsis.

Loss of FKBP5 Affects Neuron Synaptic Plasticity: An Electrophysiology Insight [PDF]

, 2019
FKBP5 (FKBP51) is a glucocorticoid receptor (GR) binding protein, which acts as a co-chaperone of heat shock protein 90 (HSP90) and negatively regulates GR.

Multiscale Organization of Neural Networks in a 3D Bioprinted Matrix

Advanced Science, EarlyView.
A 3D bioprint model of primary neurons has been engineered with a millimeter‐scale functional neural network, and it recapitulates in vivo transcriptomic features under both normal and disease conditions to the greatest extent. The successful integration of mature neurons and 3D bioprinting signifies a major advance in neuroscience modeling ...

Huntington's disease leads to decrease of GABA-A tonic subunits in the D2 neostriatal pathway and their relocalization into the synaptic cleft

Neurobiology of Disease, 2018
GABA is a widely distributed inhibitory neurotransmitter. GABA-A receptors are hetero-pentameric channels assembled in multiple combinations from 19 available subunits; this diversity mediates phasic and tonic inhibitory synaptic potentials. Whereas GABA-

In Situ Electrically Resettable Field‐Effect Transistor Biosensors for Continuous and Multiplexed Neurotransmitter Detection

Advanced Science, EarlyView.
The research team integrated a potentiometrically controlled pH electrode with carbon nanotube (CNT) field‐effect transistor (FET) biosensors on a single chip using compatible processes. By employing zonal modification and optimized pH‐sensitive probes, they achieved simultaneous quadruple‐target detection and tenfold reusability under physiological ...

Membranes and Synaptosomes Used to Investigate Synaptic GABAergic Currents in Epileptic Patients

Membranes
Among the most prevalent neurological disorders, epilepsy affects about 1% of the population worldwide. We previously found, using human epileptic tissues, that GABAergic neurotransmission impairment is a key mechanism that drives the pathological ...
