In a previous publication when we studied the purinergic receptor with which ATP interacted in mouse brain bEND.3 endothelial cells, we observed addition of 3μm ARC 118925XX (ARC; selective P2Y2 antagonist) strongly suppressed ATP‐triggered Ca2 release, suggesting the response was mediated via ...
μ m ARC 118925XX (ARC; selective P2Y 2 antagonist) strongly suppressed ATP‐triggered Ca 2+ release, suggesting the response was mediated via P2Y 2 receptors. We here report ARC unexpectedly promoted substantial Ca 2+ influx even when ATP‐triggered Ca 2+ release was largely inhibited. Since...
