Anti-GABA Antibody

Descrição detalhada : GABA (gamma-aminobutyric acid) is the major inhibitory neurotransmitter in the central nervous system that inhibits the generation of the action potential of the neuron. It is involved in the pathogenesis of certain neurological and psychiatric disorders. GABA is produced from glutamic acid in a reaction catalyzed by glutamic acid decarboxylase. In this reaction pyridoxal phosphate serves as a co-factor. GABA interacts with the GABAA and GABAB receptors, which are widely distributed throughout the nervous system and in a variety of cell types. They differ in their pharmacological, electrophysiological, and biochemical properties. GABAA-receptor complex mediates an increase in membrane conductance with an equilibrium potential near the resting level of -70 mV. This conductance increase often is accompanied by a membrane hyperpolarization, which later results in a reduction in the probability of action potential initiation. The reduction in membrane resistance is accomplished by the GABA-dependent facilitation of Cl- ion influx. GABAB receptors are coupled indirectly to K+ channels. When activated, GABAB receptors reduce Calcium ion conductance and inhibit cAMP production via intracellular mechanisms mediated by G-proteins. GABAB receptors are known to mediate both postsynaptic and presynaptic inhibition.
