Objective: GABAergic system is a target for various groups of medications including sedatives, anxiolytics, muscle relaxants, antidepressants and antiepileptics. Several foods or food ingredients are able to affect the by inhibition γ-aminobutyric acid (GABA) degrading enzymes GABA-transaminase succinate semialdehyde dehydrogenase. The purpose this study investigate inhibitory effects tea (Came...

Daytime restricted feeding (DRF) is an experimental protocol that influences the circadian timing system and underlies the expression of a biological clock known as the food entrained oscillator (FEO). Liver is the organ that reacts most rapidly to food restriction by adjusting the functional relationship between the molecular circadian clock and the metabolic networks. γ-Aminobutyric acid (GAB...

Gamma-aminobutyrate transaminase (GABA-T) catalyses the breakdown of GABA to succinic semialdehyde. In this report, the previously identified Arabidopsis thaliana (L.) Heyhn GABA-T (AtGABA-T) was characterized in more detail. Full-length AtGABA-T contains an N-terminal 36 amino acid long targeting pre-sequence (36 amino acids) that is both sufficient and necessary for targeting the enzyme to mi...

BackgroundTranscranial direct current stimulation (tDCS) to the dorsolateral prefrontal cortex (DLPFC) hypothetically modulates cognitive functions by facilitating or inhibiting neuronal activities chiefly in cerebral cortex. The effect of tDCS deeper brain region, basal ganglia-cortical circuit, remains unknown.ObjectiveTo investigate interaction between ?-aminobutyric acid (GABA) concentratio...

Malus baccata (L.) Borkh. is one of the most widely used rootstocks in apple-producing region Northern China. However, early growing season, apple roots are often subjected to suboptimal low root-zone temperatures. The regulatory effects exogenous γ-aminobutyric acid (GABA) on both shunt (GABA shunt) and respiratory activity under temperatures remain unknown. To explore physiological basis for ...

Current treatments for rheumatoid arthritis (RA) have long-term side effects such that new treatments are needed that can safely help manage the disease. There is a growing appreciation that GABA receptors (GABA-Rs) on immune cells provide new targets that can be used to modulate immune cell activity. Here, we show for the first time that activation of peripheral GABA-Rs can inhibit the develop...

Abamectin has been widely used as an insecticide/acaricide for more than 30 years because of its superior bioactivity. Recently, an interesting phenomenon was identified in the carmine spider mite, Tetranychus cinnabarinus, an important pest in agriculture. The gamma aminobutyric acid (GABA) contents in a laboratory abamectin resistant strain of T. cinnabarinus (AbR) were significantly increase...

Gamma-aminobutyric acid (GABA) is a non-protein amino acid commonly present in all organisms. Because cellular levels of GABA in plants are mainly regulated by synthesis (glutamate decarboxylase, GAD) and catabolism (GABA-transaminase, GABA-T), we attempted seed-specific manipulation of the GABA shunt to achieve stable GABA accumulation in rice. A truncated GAD2 sequence, one of five GAD genes,...

Gamma-aminobutyric acid transaminase (GABA-T) catalyses the breakdown of GABA to succinic semialdehyde. In this report, three GABA-T isoforms were identified in the tomato (Solanum lycopersicum L.) plant. The deduced amino acid sequences of the three isoforms are highly similar over most of their coding regions with the exception of their N-terminal regions. Transient expression of the individu...

During acute infection in human and animal hosts, the obligate intracellular protozoan Toxoplasma gondii infects a variety of cell types, including leukocytes. Poised to respond to invading pathogens, dendritic cells (DC) may also be exploited by T. gondii for spread in the infected host. Here, we report that human and mouse myeloid DC possess functional γ-aminobutyric acid (GABA) receptors and...
