Coupling of Brain Muscarinic Receptors to Second Messengers.
Abstract
Stimulating muscarinic acetylcholine receptors results in activation of various signal transduction pathways. The goal of the research was to investigate the selectivity of coupling of the currently known 5 subtypes of muscarinic receptors to these different second messenger pathways. Results indicate that m1, m3 and m5 muscarinic receptors are coupled to enhanced phosphoinositide hydrolysis, while m2 and m4 receptors are coupled to a decrease in cyclic AMP formation. Results also demonstrate efficient coupling of m5 muscarinic receptors to generation of nitric oxide.
