摘要
Acetylcholine calms the heartbeat by activating G(i)-coupled receptors and G-protein-activated inwardly rectifying potassium (GIRK) channels. It also dampens the GIRK current by reducing PIP2 through G(q)-coupled receptors, These two types of receptors seem to be engaged in an intriguingly specific form of crosstalk, which leads to desensitization of the GIRK current.
