GABA-A Receptor Modulation

Meaning

GABA-A Receptor Modulation refers to the process of altering the function of the Gamma-Aminobutyric Acid Type A receptor, a principal inhibitory neurotransmitter receptor in the central nervous system. This modulation typically involves allosteric binding of various compounds, which either potentiate or diminish the receptor’s response to its endogenous ligand, GABA. The clinical objective is often to enhance inhibitory neurotransmission, thereby promoting anxiolytic, sedative, or anticonvulsant effects. This mechanism is central to the action of several pharmacological agents impacting neuroendocrine function and the stress response.
