Although gamma-aminobutyric acid (GABA)A receptor alpha subunits are important for benzodiazepine (BZD) binding and GABA-current potentiation by BZDs, the presence of a gamma subunit is required for high affinity BZD effects. To determine which regions unique to the gamma2S subunit confer BZD binding and potentiation, we generated chimeric protein combinations of rat gamma2S and alpha1 subunits...

Depolarization of cultured astrocytes by KCl stimulated gamma-aminobutyric acid (GABA) release in a dose-dependent manner. At 60 mM KCl, the stimulatory effect was calcium- and sodium- independent, and was not altered by the presence of beta-alanine. The potassium-evoked GABA release was inhibited by furosemide and 4-acetamido-4' -isothiocyano-2,2'-stilbene disulfonic acid (SITS), blockers of t...

The aim of the study was to assess changes in physical performance parameters progeny rats with experimental preeclampsia (EP) undergoing early and late pharmacological treatment gamma- aminobutyric acid (GABA) derivatives. Materials methods . At first stage, 3- 18-month old female EP after (from 40 th 70 day life) GABA derivatives, succicard (22mg/kg), salifen (7.5 mg/kg), phenibut (25 mg/kg) ...

The conformational behaviour and GABA receptor activity of the different stereoisomers of 2,3-difluoro-4-aminobutyric acid are described. Two enantiomeric GABA(C)-active ligands are identified, one of which is an agonist while the other is an antagonist. The results support an existing QSAR model of the bioactive geometry of GABA at GABA(C).

Objective(s) Diabetes related dysfunction of resistance vessels is associated with vascular occlusive diseases. Vasorelaxant agents may have a role in control of diabetic cardiovascular complications. Gamma aminobutyric acid (GABA) has demonstrated to cause vasorelaxation. The present study was designed to determine i) the vasorelaxatory effect of GABA on diabetic vessels and ii) the role of en...

Glutamic acid decarboxylase (GAD) is an intracellular enzyme found in the presynaptic end of nerve terminals that functions to synthesize ​​gamma-aminobutyric (GABA) via decarboxylation. Autoantibodies GAD65 isoform have been high levels neurological disorders including stiff person syndrome (SPS), autoimmune encephalitis, and refractory epilepsy. Low anti-GAD65 also noted type 1 diabetes melli...

Vigabatrin and gabaculine, both highly specific inhibitors of GABA (gamma-aminobutyric acid) transaminase, cause significant elevation of endogenous GABA levels in brain. The time course of GABA concentration after acute GABA transaminase inhibition was measured quantitatively in the alpha-chloralose-anesthetized rat brain using in vivo selective homonuclear polarization transfer spectroscopy. ...

GABA(B) (gamma-aminobutyric acid type B) receptors are important for keeping neuronal excitability under control. Cloned GABA(B) receptors do not show the expected pharmacological diversity of native receptors and it is unknown whether they contribute to pre- as well as postsynaptic functions. Here, we demonstrate that Balb/c mice lacking the GABA(B(1)) subunit are viable, exhibit spontaneous s...

Gamma-aminobutyric acid is a precursor of nylon-4, which is a promising heat-resistant biopolymer. GABA can be produced from the decarboxylation of glutamate by glutamate decarboxylase. In this study, a synthetic scaffold complex strategy was employed involving the Neurospora crassa glutamate decarboxylase (GadB) and Escherichia coli GABA antiporter (GadC) to improve GABA production. To constru...
