Effect of oATP on Panx1 currents and P2X7R-mediated currents induced by 100 µM BzATP. con, voltage-induced Pannx1 currents or BzATP-induced P2X7R currents in the absence of oATP. Oocytes expressing Panx1 or P2X7R were preincubated with 100 µM oATP for 2–3 h before measurements of membrane currents. oATP only attenuated BzATP-induced currents in P2X7R-expressing oocytes. Means ± SD are plotted, and n is indicated.
