Adenosine triphosphate (ATP) activates two receptor superfamilies, metabotropic P2Y and ionotropic P2X receptors. The P2X receptors are nonselective cation channels that are widely expressed on excitable cells including neurons, glia, and smooth muscle cells. The protocols in this unit are

We have characterized PPADS (pyridoxalphosphate-6-azophenyl-2',4'-disulfonic acid) as a novel antagonist which selectively blocks P2 purinoceptor-mediated responses in rabbit vas deferens at pre- and postjunctional sites. PPADS did not interact with alpha 1-adrenoceptors, muscarinic M2 and M3 receptors, histamine H1 and
