Effect of BzATP on ATP-induced currents of hP2X4/hP2X7-coexpressing oocytes. (A–C) Two-electrode voltage clamp measurements showing the effect of BzATP on ATP-induced currents of oocytes expressing (A) hP2X4, (B) hP2X7, or (C) hP2X4 + hP2X7. (D) BzATP-induced currents measured in P2X4/P2X7-coexpressing oocytes were compared with the sum of P2X4- and P2X7-dependent current amplitudes (shown in parts A,B, respectively). Mean current amplitudes were not significantly different at any time point, indicating the lack of a distinct P2X4/P2X7 phenotype related to BzATP stimulation. means ± SD from 5–6 oocytes.
