In molecular biology and physiology, something is GABAergic or GABAnergic if it pertains to or affects the neurotransmitter gamma-aminobutyric acid (GABA). For example, a synapse is GABAergic if it uses GABA as its neurotransmitter, and a GABAergic neuron produces GABA.
The death of Purkinje cells as a result of gluten exposure is irreversible. Early diagnosis and treatment with a gluten-free diet can improve ataxia and prevent its progression. [38] [41] Less than 10% of people with gluten ataxia present any gastrointestinal symptom, yet about 40% have intestinal damage. [41]
Most neurons secrete with glutamate or GABA. Glutamate is excitatory, meaning that the release of glutamate by one cell usually causes adjacent cells to fire an action potential. (Note: Glutamate is chemically identical to the MSG commonly used to flavor food.) GABA is an example of an inhibitory neurotransmitter. Monoamine neurotransmitters:
A GABA A receptor negative allosteric modulator is a negative allosteric modulator (NAM), or inhibitor, of the GABA A receptor, a ligand-gated ion channel of the major inhibitory neurotransmitter γ-aminobutyric acid (GABA). [1] [2] They are closely related and similar to GABA A receptor antagonists.
A GABA reuptake inhibitor (GRI) is a type of drug which acts as a reuptake inhibitor for the neurotransmitter gamma-Aminobutyric acid (GABA) by blocking the action of the gamma-Aminobutyric acid transporters (GATs). This in turn leads to increased extracellular concentrations of GABA and therefore an increase in GABAergic neurotransmission. [1]
The mechanism behind this action is unclear however, [11] with some researchers suggesting that FQs may act as low-affinity GABA-A antagonists, [12] and others positing that its interactions with N-methyl-D-aspartate (NMDA) receptors, which have been associated with fear, anxiety, and depression, may be responsible for the anxiogenic effects.

GABRA2 is an alpha subunit that is part of GABA-A receptors, which are ligand-gated chloride channels and are activated by the major inhibitory neurotransmitter in the mammalian brain, GABA. Chloride conductance of these channels can be modulated by agents, such as benzodiazepines (psychoactive drugs) that bind to the GABA-A receptor.
