Photomotor Responses in Zebrafish and Electrophysiology Reveal Varying Interactions of Anesthetics Targeting Distinct Sites on Gamma-Aminobutyric Acid Type A Receptors

Authors: Helen Hoyt, BS et al  Anesthesiology August 2022. Background Etomidate, barbiturates, alphaxalone, and propofol are anesthetics that allosterically modulate GABAA receptors via distinct sets of molecular binding sites. Two-state concerted co-agonist models account for anesthetic effects and predict supra-additive interactions between drug pairs acting at distinct sites. Some behavioral and molecular studies support these predictions, while other […]
