We have investigated whether prejunctional inhibitory muscarinic receptors ("autoreceptors") exist on cholinergic nerves in human airways in vitro and whether guinea pig trachea provides a good model for further pharmacological characterization of these receptors. Pilocarpine was used as a selective agonist and gallamine as a selective antagonist of these(More)
Several subtypes of muscarinic receptors have been identified in airways and lung parenchyma of different species, including humans. M1 receptors may be present in parasympathetic ganglia where they appear to facilitate ganglionic neurotransmission. M2 receptors seem to be located on cholinergic nerve endings where they function as "autoreceptors,"(More)
