1 The nAChR subtype mediating nicotine-induced dilation in isolated porcine basilar arterial rings denuded of endothelium was therefore examined pharmacologically and immunohistochemically. Nicotine cholinergic receptor nicotinic alpha 4 subunit Homo sapiens
2 Results from using an in vitro tissue bath technique indicated that relaxation induced by nicotine (100 microM) was blocked by preferential alpha7-nAChR antagonists (methyllycaconitine and alpha-bungarotoxin) and nonspecific nAChR antagonist (mecamylamine) in a concentration-dependent manner, but was not affected by dihydro-beta-erythroidine (a preferential alpha4-nAChR antagonist). Nicotine cholinergic receptor nicotinic alpha 4 subunit Homo sapiens
