2D chemical structure image of ab120102, ZD7288, Sino-atrial node function modulator
Membrane currents during slow voltage ramps from ?120 mV to ?40 mV in the presence of TTX (0.5 μM) and ZD7288 (50 μM), and during subsequent bath application of CCh (light grey line; 50 μM; B1) show that cholinergic receptor activation induces an inward current at voltages near resting membrane potential that reverses around ?76 mV, consistent the blockade of outward K+ currents. The application of CCh occluded additional inward current during subsequent bath application of XE-991 (dark grey line; 10 μM) sμggesting that CCh depolarizes PaS neurons in part by suppression of the M-current. Current subtractions show that CCh blocks an outward current that reverses at ?83.3±7.0 mV (black line; B2), and also occluded membrane currents normally induced by XE-991 (grey line).
