Nicotinic acetylcholine receptor (nAChR) α4 and β2 subunits assemble in two alternate stoichiometries to produce (α4β2)(2)α4 and (α4β2)(2)β2, which display different agonist sensitivities. Functionally relevant agonist binding sites are thought to be located at α4(+)/β2(-) subunit interfaces, but because these interfaces are present in both receptor(More)
BACKGROUND AND PURPOSE Nicotinic ACh (α4β2)2α4 receptors are highly prone to desensitization by prolonged exposure to low concentrations of agonist. Here, we report on the sensitivity of the three agonist sites of the (α4β2)2α4 to desensitization induced by prolonged exposure to ACh. We present electrophysiological data that show that the agonist sites of(More)
Eosinophilic with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome) is a rare systemic disease characterized by a small-vessel necrotizing vasculitis. Cardiac manifestations are broad-ranging and are associated with a poor prognosis. Coronary vasospasm is uncommon.Here, we report a case of an acute coronary vasospasm in a patient with EGPA after(More)
