cAMP-mediated activation of PKA reduces the unitary conductance of wild-type α3GlyRs. (A) Single channel current traces obtained from cells co-expressing α3GlyRs and bPAC in the absence and presence of blue light. Calibration bar, 5 pA, 1 s. (B) Time course of the average amplitude of the events after blue light exposure (from minute 3) or in control conditions (12 minutes in no light condition). (C) The histograms show the amplitude distributions of control cells (left) and cells stimulated with blue light (right). (D) The plot summarizes the main conductance of α3GlyRs after blue light exposure or after the application of 8-Br-cAMP. Differences were significant (***P < 0.001; ANOVA followed by Bonferroni post-hoc test, F(2, 14) = 123.4). Control, n = 5; Blue light, n = 5; 8-Br-cAMP, n = 5.
