Figure 1

Oscillating currents induced by P2Y receptor agonists. (a) ATP, (b) UTP and (c) UDP (all 10-4 M), added as indicated by the horizontal bars, evoked oscillating inward currents in smooth muscle cells isolated from SPA (a & c) and LPA (b) and voltage-clamped at -50 mV. The insets show W-shape currents induced by (a) ATP and (b) UTP. The arrow on the left-hand side of each trace indicates zero holding current.
