Evidence for the Expression of Multiple Uracil Nucleotide‐Stimulated P2 Receptors Coupled to Smooth Muscle Contraction in Porcine Isolated Arteries

Abstract

We conclude that UTP-evoked contraction of porcine coronary artery smooth muscle appears to be predominantly P2Y2-mediated, while the ear artery appears to express a uracil nucleotide-sensitive P2 receptor(s) which fails to fit readily into the current classification.
