Effect of PSB-14517 on ATP-induced currents of hP2X4/hP2X7-coexpressing oocytes. Two-electrode voltage clamp measurements showing ATP-induced current amplitudes (Iact,3s) at 3 s after the application of 0.1 mM ATP. The theoretical current remaining after PSB-14517 application to hP2X4/hP2X7-expressing oocytes (rightmost column) was calculated as described in Section “Results.” The theoretical current amplitude was not significantly different from the measured value (next to rightmost column), indicating the lack of a distinct P2X4/P2X7 phenotype related to PSB-14517, which may be explained by PSB-14517 affecting only homomeric P2X4 receptors. Data are means ± SD from 4–11 oocytes.
