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.

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 ...

Isovaline does not activate GABA(B) receptor-coupled potassium currents in GABA(B) expressing AtT-20 cells and cultured rat hippocampal neurons.

PLoS ONE, 2015
Isovaline is a non-proteinogenic amino acid that has analgesic properties. R-isovaline is a proposed agonist of the γ-aminobutyric acid type B (GABA(B)) receptor in the thalamus and peripheral tissue.

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

Neurally Released GABA Acts via GABAC Receptors to Modulate Ca2+ Transients Evoked by Trains of Synaptic Inputs, but Not Responses Evoked by Single Stimuli, in Myenteric Neurons of Mouse Ileum

Frontiers in Physiology, 2018
γ-Aminobutyric Acid (GABA) and its receptors, GABAA,B,C, are expressed in several locations along the gastrointestinal tract. Nevertheless, a role for GABA in enteric synaptic transmission remains elusive.

Genetic Downregulation of GABA_B Receptors from Oligodendrocyte Precursor Cells Protects Against Demyelination in the Mouse Spinal Cord

Cells
GABAergic signaling and GABAB receptors play crucial roles in regulating the physiology of oligodendrocyte-lineage cells, including their proliferation, differentiation, and myelination.

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.

γ-aminobutyric acid type A receptors modulate neurosteroid binding to the voltage-dependent anion channel

Acta Chimica Slovenica
Neurosteroids modulate the function of γ-aminobutyric acid type A (GABAA) receptors in the brain. We showed that GABAA receptors modulate neurosteroid interactions with VDAC. GABA enhanced [3H]6-AziP labeling of VDAC in a concentration-dependent manner.

The involvement of GABA-rho receptors in regulating ethanol-induced elevation of dopamine, glycine and taurine within the nucleus accumbens of Wistar rats

Frontiers in Pharmacology
IntroductionAlcohol use disorder (AUD) causes significant morbidity and mortality globally. Ethanol’s rewarding and reinforcing effects are attributed to activation of the mesolimbic dopamine system, increasing accumbal dopamine release. While activation
