The action of the neurotransmitter acetylcholine is mediated through two types of receptors, the ionotropic nicotinic receptors and the metabotropic muscarinic receptors. The muscarinic receptors belong to the superfamily of 7-transmembrane G-protein coupled receptors. Five subtypes of muscarinic receptors have been cloned and are named M1-M5.1-2The muscarinic receptors are widely distributed throughout the body but are predominantly expressed in the parasympathetic nervous system and exert both excitatory and inhibitory control over central and peripheral tissues.1-2Muscarinic receptors participate in a number of physiological functions such as regulation of heart rate, muscle contraction, cognition, sensory processing, and motor control.1 They also participate in learning and memory processing.3-4The M2 receptor is considered to be the predominant muscarinic receptor subtype that is expressed in cardiac muscle.5The M2 and M4 receptors mediate Ca2+ channel inhibition and Kir3 K+ channel activation by directly binding the Gβγ subunit to the channel.6, 7 Stimulation of the M2 receptor by acetylcholine in the heart results in activation of the Kir3.1/Kir3.4 channels causing a slowing in heart beat.7
