Expression of RGS2 or PLCβ-ct reduces VI modulation. A–C, Sample current traces (left) and corresponding time courses (right) for uninjected cells and cells expressing RGS2 or PLCβ-ct, respectively. The voltage protocol is the same as in Figure 1A. Calibration: 1 nA, 20 msec for all current traces. D, E, Bar graphs indicating average (+SEM) prepulse (filled bars) and postpulse (open bars) inhibition for uninjected (control) cells and cells expressing RGS2 and PLCβ-ct for untreated cells (D) and cells treated with 0.5 μg/ml PTX (E).
