gaba是哺乳动物大脑中主要的抑制性神经递质，它作用于gaba-a受体，gaba-a受体是配体门控的氯通道。这些通道的氯离子电导可以通过与gaba-a受体结合的苯二氮卓类药物来调节。至少有16个不同的gaba-a受体亚单位被鉴定出来。[由RefSeq提供，2008年7月]
GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. At least 16 distinct subunits of GABA-A receptors have been identified.
