Infection with SARS-CoV-2, the causative agent of COVID-19 pandemic, originated in China and quickly spread across globe. Despite tremendous economic healthcare devastation, research on this virus has contributed to a better understanding numerous molecular pathways, including those involving γ-aminobutyric acid (GABA), that will positively impact medical science, neuropsychiatry, post-pandemic...

γ-Aminobutyric acid (GABA) is an inhibitory neurotransmitter having anti-anxiety, stress-reducing and sleep-enhancing effects. The blood GABA concentration has the potential to become a diagnostic index for depression schizophrenia. In this study, we developed method quantification of in human serum by liquid chromatography/electrospray ionization-tandem mass spectrometry (LC/ESI-MS/MS) combine...

Introduction Licorice could exhibit beneficial effect in the management of insomnia by regulating key modulators such as GABA and serotonin, we therefore aimed to study potentail hypnotic licorice extract, glycyrrhizin (GCZ), on underlying mechanisms. Material methods Mice were randomly grouped a Control group, GCZ (low) (high) group DZP with 8 mice each group. Sleep latency, sleep duration loc...

background: the present study evaluated the effects of treadmill running on extracellular basal levels of glutamate and gaba at dentate gyrus of streptozotocin-induced diabetic rats. methods: after 12 weeks of diabetes induction and exercise period, extracellular levels of glutamate and gaba were investigated. results: the results showed that glutamate levels were significantly decreased in dia...

Ambient GABA in the brain tonically activates extrasynaptic GABA(A) receptors, and activity-dependent changes in ambient GABA concentration can also activate GABA(B) receptors. To investigate an interaction between postsynaptic GABA(B) and GABA(A) receptors, we recorded GABA(A) currents elicited by exogenous GABA (10 μm) from dentate gyrus granule cells (DGGCs) in adult rat hippocampal slices. ...

Gamma aminobutyric acid (GABA) is one of the inhibitory neurotransmitters that may have the ability torelieve the intensity of stress. Heat stress remains a major threat for duck production in summer in most areas of China. The current study was conducted to investigate the effect of dietary GABA on performanceparameters and plasma metabolites of heat exposed ducks. Two thousand Cherry Valley d...

The neurotransmitter gamma-aminobutyric acid (GABA) mediates inhibitory signaling in the brain via stimulation of both GABA(A) receptors (GABA(A)R), which are chloride-permeant ion channels, and GABA(B) receptors (GABA(B)R), which signal through coupling to G proteins. Here we report physical interactions between these two different classes of GABA receptor. Association of the GABA(B) receptor ...

GABA(B) receptors are G-protein-coupled receptors that mediate slow synaptic inhibition in the brain and spinal cord. These receptors are heterodimers assembled from GABA(B1) and GABA(B2) subunits, neither of which is capable of producing functional GABA(B) receptors on homomeric expression. GABA(B1,) although able to bind GABA, is retained within the endoplasmic reticulum (ER) when expressed a...

There is a recent trend of using lactic acid bacteria for the production gamma-aminobutyric (GABA). This study described method that combines fermentation and self-buffered whole-cell catalysis efficient GABA Levilactobacillus brevis CD0817. Upon completion fermentation, cells were recovered to conduct by which substrate L-glutamic was catalytically decarboxylated GABA. itself maintained acidit...
