Abstract
We have previously shown that neuropeptide Y (NPY) increases cytosolic free Ca2+ concentration [( Ca2+]i) in porcine aortic smooth muscle cells. In this study, specific NPY receptor binding sites were identified in the cells by use of [125I]Bolton-Hunter NPY [( 125I]BH-NPY). Binding was to a single …
