Levels of gamma-aminobutyric acid (GABA) in cerebrospinal fluid (CSF) were measured by radioreceptor assay (RRA) in 25 normal controls and in 121 patients with various central nervous system disorders. CSF-GABA levels could be measured down to 5 pmoles/ml reliably by this assay. In normal controls, the mean (+/- SEM) GABA level in CSF was 127 +/- 5.2 pmoles/ml. There was no correlation between ...

gamma-Aminobutyric acid (GABA) is a transmitter of enteric interneurons, targeting excitatory GABA(A) or inhibitory GABA(B) receptors that modulate motility and mucosal function. Enteric GABA may also subserve hormonal and paracrine signaling. Disruption in gastrointestinal function following perturbation of enteric GABA receptors presents potential new target sites for drug development.

Gamma-aminobutyric acid (GABA) is a non-protein amino known for its role in the nervous system of animals. However, research has also revealed presence and function plants recently. In plants, GABA signal molecule involved multiple physiological processes, including stress response, growth, development. This review aims to present thorough summary current knowledge regarding plants. We begin by...

gamma-amino butyric acid (gaba) possesses several physiological functions such as neurotransmission, induction of hypotension, diuretic and tranquilizer effects. production of gaba-enriched products by lactic acid bacteria has been a focus of different researches in recent years because of their safety and health-promoting specifities. in this study, glutamate decarboxylase (gad) gene of a loca...

The Gamma-aminobutyric acid (GABA) and glutamate (Glu) neurotransmitter systems are implicated in depression. While previous studies found reduced GABA levels, a tendency towards Glu, using proton (1H) magnetic resonance spectroscopy (1H-MRS), little is known about GABAA receptor availability Here, the aim was to characterize Glu-levels dorsal anterior cingulate cortex (dACC), whole-brain avail...

Cerebrospinal fluid gamma-aminobutyric acid (CSF-GABA) was analysed by radioreceptor assay in 16 normal controls and 84 patients with various neurological and psychiatric diseases. In patients with spinocerebellar degeneration, neuro-Beh9et's syndrome and Parkinson's disease, CSF-GABA levels were decreased. On the other hand, increased CSF-GABA levels were detected in patients with meningitis.

background: there are some reports in the literature showing that hypothalamus synthesizes and secretes amino acid neurotransmitters. according to several studies, elevated serum levels of gamma-amino butyric acid (gaba), a potent inhibitory neurotransmitter, have recently been implicated in the pathogenesis of neural diseases. the purpose of this research was to estimate the effects of curcumi...
