The sympathetic nervous innervation is split into two portions: postganglionic adrenergic nerves that synapse on blood vessels and the smooth muscle that surround the alveoli, and sympathetic cholinergic nerves that innervate the glandular epithelium.
Down-regulation occurs after prolonged agonist treatment (hours to days), resulting in a loss of receptor binding sites [ 2 3 4 ] . The processes involved in homologous desensitization have been extensively investigated for the beta-2 adrenergic receptor, which is the prototypical G protein-coupled receptor.
The alpha-2 adrenergic receptors also undergo agonist-induced desensitization and down-regulation.
The phosphorylated beta-2 receptor enhances the binding of beta-arrestin, which not only uncouples the receptor from the signal transduction process but also serves as an adapter protein that mediates entry into the internalization pathway [ 5 ] , as well as serving as a platform for additional signaling pathways [ 6 ] . The mechanisms of beta-2 adrenergic receptor down-regulation appear to involve both an increase in the rate of degradation of the receptor as well as a decrease in the levels of beta receptor mRNA [ 7 ] . Down-regulation of the beta-2 receptor is, in part, due to trafficking of the beta-2 receptor to lysosomes via the clathrin-coated pit endosomal pathway [ 8 9 ] .
