Oral adenosine-5’-triphosphate (ATP) administration increases blood flow following exercise animals and humans
2015/7/29
Extracellular adenosine triphosphate (ATP) stimulates vasodilation by binding to endothelial ATP-selective P2Y2 receptors; a phenomenon, which is posited to be accelerated during exercise. Herein, we ...
