一般說明

γ-氨基丁酸 (GABA) 是一种非氨基蛋白质,存在于植物、动物和微生物中。GABA已应用于制药和食品工业,作为奶酪、烧酒、金白龙茶和精油成分。
研究领域:神经科学

應用

γ-氨基丁酸(GABA)用于:
  • 制备GABA-BSA(牛血清蛋白)-GA(戊二醛)复合物,用于GABA免疫染色对照。
  • 核磁共振(MRS)高分子抑制检测。
  • GABA肠内给药,降低管腔内液体分泌

生化/生理作用

GABA(γ-氨基丁酸)是一种氨基酸,作为中枢神经系统中的抑制性神经递质,在某些外周组织中也可用作神经调节剂。其可与GABAA受体结合,抑制信号接收神经元活性。GABAA受体能够在神经细胞细胞膜形成通道。一旦和GABA结合,受体被激活,允许带负电的分子,比如氯离子通过通道,进入细胞。这导致细胞兴奋性降低。
GABA 能神经元参与肌肉松弛、抗焦虑治疗、镇静和麻醉。GABA 还可影响心率和血压。
GABA可以改善大脑中的血浆浓度、生长激素和蛋白质合成。它还在降低人体血压方面发挥作用。GABA 是一种有效的降压药、利尿剂和抗糖尿病 药。它还可调节血脂水平和疼痛感。
大脑中的主要抑制性神经递质;GABAA 和 GABAB 受体激动剂;增加 Cl 的传导性。

The neurotransmitter gamma-aminobutyric acid (GABA) inhibits the activity of signal-receiving neurons by interacting with the GABAA receptor on these cells. The GABAA receptor is a channel-forming protein that allows the passage of chloride ions into the cells. Excessive GABAA activation

GABA (γ-aminobutyric acid) is a four carbon non-protein amino acid that is widely distributed in plants, animals and microorganisms. As a metabolic product of plants and microorganisms produced by the decarboxylation of glutamic acid, GABA functions as an inhibitory neurotransmitter

The antiepileptic drug candidate, padsevonil, is the first in a novel class of drugs designed to interact with both presynaptic and postsynaptic therapeutic targets: synaptic vesicle 2 proteins and γ-aminobutyric acid type A receptors (GABAA Rs), respectively. Functional aspects of

Intuitively one might expect that activation of GABAergic inhibitory neurons results in bradycardia. In conscious animals the opposite effect is however observed. GABAergic neurons in nucleus ambiguus hold the ability to control the activity of the parasympathetic vagus nerve that

γ-Aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the central nervous system, and it is produced via the enzymatic activity of glutamic acid decarboxylase (GAD). GABA generates fast biological signaling through type A receptors (GABA(A)R), an anionic channel. Intriguingly
