ATP can activate several Ca(2+) influx channels in vascular endothelial cells. For example, it stimulates TRPC channels via capacitative and noncapacitative Ca(2+) entry (CCE and non-CCE, respectively) mechanisms; it also directly acts on P2X purinoceptors, resulting in Ca(2+) influx. In the present study, we tested the hypothesis that cyclic nucleotide-gated (CNG) channels also contribute to ATP-induced non-CCE.
