Effect of the M3 muscarinic ACh receptor antagonist 4-DAMP and the nicotinic ACh receptor antagonist mecamylamine on ACh-induced KNa channel activity in isolated Kenyon cells. A, top: representative traces of KNa channel current in the control (left) and 10 μM ACh + 1 μM 4-DAMP (right) groups. Bottom: corresponding all-point amplitude histograms. C and O, closed and complete opening levels, respectively. B: NPo before drug application (Control) and in the presence of 10 μM ACh + 1 μM 4-DAMP (ACh + 4-DAMP). Matching symbols connected with a line show the sequential experiment in the same cell. C, top: representative traces of KNa channel current in the control (left) and 10 μM ACh + 20 μM mecamylamine (right) groups. Bottom: corresponding all-point amplitude histograms. D: NPo before drug application (Control) and in the presence of 10 μM ACh + 20 μM mecamylamine (ACh + Mecamylamine). B and D: paired t-test; *P < 0.05.
