The GABA receptors are a class of receptors that respond to the neurotransmitter gamma-aminobutyric acid (GABA), the chief inhibitory compound in the mature vertebrate central nervous system. There are two classes of GABA receptors: GABA A and GABA B .
GABA transporters (gamma-aminobutyric acid transporters) are a family of neurotransmitter / sodium symporters, belonging to the solute carrier 6 family. [1] [2] They are found in various regions of the brain in different cell types, such as neurons and astrocytes.
Neurotransmitters are essential to the function of complex neural systems. The exact number of unique neurotransmitters in humans is unknown, but more than 100 have been identified. [3] Common neurotransmitters include glutamate, GABA, acetylcholine, glycine, dopamine and norepinephrine.
In the mammalian brain, two predominant, differentially expressed isoforms of the GABA B1 are transcribed from the Gabbr1 gene, GABA B(1a) and GABA B(1b), which are conserved in different species including humans. [12] This might potentially offer more complexity in terms of the function due to different composition of the receptor. [12]
The only difference noted so far is a slight elevation of brain Taurine levels. [2] This was an unexpected finding, but is in agreement with the notion that GAT2 permits efflux of GABA and taurine from the brain to circulating blood through the blood brain barrier. [3]
Purkinje cells mainly release GABA (gamma-aminobutyric acid) neurotransmitter, which inhibits some neurons to reduce nerve impulse transmission. Purkinje cells efficiently control and coordinate the body's motor motions through these inhibitory actions. [3] [4]
The GABA neurotransmitter mediates the fast synaptic inhibition in the central nervous system. When GABA is released from its pre-synaptic cell, it will bind to a receptor (most likely the GABA A receptor) that causes the post-synaptic cell to hyperpolarize (stay below its action potential threshold). This will counteract the effect of any ...
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
