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.

RNA editing regulates insect gamma-aminobutyric acid receptor function and insecticide sensitivity [PDF]
, 2008 A-to-I pre-mRNA editing by adenosine deaminase enzymes has been reported to enhance protein diversity in the nervous system. In Drosophila, the resistance to dieldrin (RDL) gamma-aminobutyric acid (GABA) receptor subunit displays an editing site (R122 ...

Interaction of hypothalamic GABA\u3csub\u3eA\u3c/sub\u3e and excitatory amino acid receptors controlling heart rate in rats [PDF]
, 1991 We have previously shown that microinjection of drugs that impair gamma-aminobutyric acid (GABA)-mediated synaptic inhibition into the dorsomedial hypothalamus (DMH) of rats generates cardiovascular and behavioral changes that mimic the response to ...

γ1-Containing GABA-A Receptors Cluster at Synapses Where they Mediate Slower Synaptic Currents than γ2-Containing GABA-A Receptors [PDF]
Frontiers in Molecular Neuroscience, 2017 GABA-A receptors (GABAARs) are pentameric ligand-gated ion channels that are assembled mainly from α (α1-6), β (β1-3) and γ (γ1-3) subunits. Although GABAARs containing γ2L subunits mediate most of the inhibitory neurotransmission in the brain, significant expression of γ1 subunits is seen in the amygdala, pallidum and substantia nigra.

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