ATP receptor antagonist blocks propagation of ATP release wave. Spatial profiles of ATP concentration at the retinal surface are shown for five time points after stimulation.Left, Control trial. Immediately after stimulation (1.3 sec) ATP release is confined to a region near the stimulation site (center of trace). At later times ATP release occurs at greater distances from the stimulation site. Right, Suramin, 100 μm. ATP release is confined to a small region near the stimulation site, even at later times. ATP release does not propagate to neighboring regions. Shown are recordings from whole-mount retinas.
