Gamma‐aminobutyric acid (GABA) possibly plays a causative role in mood disorders. This hypothesis originated with studies on the beneficial effect of valproate in mania and as a mood stabilizer. Since valproate is known for its action in increasing the level of GABA, it was indirectly suggested that decreasing levels of GABA were responsible for mood alterations. To identify factors causing the...
glutamate decarboxylase enzyme produces γ-aminobutyric acid (gaba) in a non-reversible decarboxylation reaction of glutamate. gaba is a major inhibitory neurotransmitter of the brain and it is also present at high concentration in other organs such as pancreatic islets. gaba has effects on blood pressure, diabetes, inflammation, sleeplessness and depression. some bacteria such as lactobacillus ...
A successful unified pharmacophore/receptor model which has guided the synthesis of subtype selective compounds is reviewed in light of recent developments both in ligand synthesis and structural studies of the binding site itself. The evaluation of experimental data in combination with a comparative model of the alpha1beta2gamma2 GABA(A) receptor leads to an orientation of the pharmacophore mo...
Abstract Gamma-aminobutyric acid (GABA) and glutamate are the primary neurotransmitters responsible for modulating excitatory inhibitory signalling within human brain. Dysfunctional GABAergic glutamatergic has been identified as a key factor in range of neuropsychiatric conditions; hence measurement modulation these neurometabolites is important improving our understanding conditions treatment ...
Borna disease virus (BDV) is one of the infectious agents that causes diseases of the central nervous system in a wide range of vertebrate species and, perhaps, in humans. The phosphoprotein (P) of BDV, an essential cofactor of virus RNA-dependent RNA polymerase, is required for virus replication. In this study, we identified the gamma-aminobutyric acid receptor-associated protein (GABARAP) wit...
gamma-Aminobutyric acid (GABA) and glycine are major inhibitory neurotransmitters that are released from nerve terminals by exocytosis via synaptic vesicles. Here we report that synaptic vesicles immunoisolated from rat cerebral cortex contain high amounts of GABA in addition to glutamate. Synaptic vesicles from the rat medulla oblongata also contain glycine and exhibit a higher GABA and a lowe...
spreading depression (sd), discovered by leao in 1944, is a pathophysiological wave which propagates slowly in the brain (3 mm/min) and cause dramatic ionic and hemodynamic changes. sd appears to act through several mechanisms and receptors which have not completely understood. here, we studied the effect of inhibitory system in animal model of sd using immunohistochemistry technique. after imp...
The present study was designed to gain insight into the effects of s-limonene on the brain after 1-wk administration. For this purpose, neurotransmitters such as dopamine (DA), serotonin (5-HT), gamma-aminobutyric acid (GABA), glutamic acid (Glu) and some of their metabolites (DOPAC and 5-HIAA) were determined by HPLC-ECD and amino acid analyzer after 1-wk administration of s-limonene of differ...
