Web26 mrt. 2024 · The ion channels associated with the ethanol action include N-methyl-d-aspartate receptors , γ-amino butyric acid receptors , and G-protein–activated inwardly rectifying potassium channels (GIRK) (8–10). GIRK is a member of the inwardly rectifying potassium channel (Kir) family, which regulates neural excitabilities (11, 12). WebInward rectifier currents expressed in the heart are constituted by pore-forming alpha-subunits of Kir2, Kir3, and Kir6 subfamilies. Characteristic properties of inward rectifiers comprise small outward conductances that nevertheless are important to terminal repolarization of cardiac action potentials.
