Differential effects of apamin on Ca2+-dependent K+ currents in bullfrog sympathetic ganglion cells.

K Tanaka, S Minota, K Kuba, K Koyano, T Abe.   

Abstract

In B-type neurones of bullfrog sympathetic ganglia, apamin (10 nM) suppressed the Ca2+-dependent K+ current (IAH) involved in the afterhyperpolarization of an action potential, while it did not affect the Ca2+-dependent K+ current (Ic) underlying the spike repolarization. IAH was further separated into two exponential components which were differentially affected by apamin, voltage and alterations in Ca2+ influx, suggesting the existence of 3 different types of Ca2+-dependent K+ channel in bullfrog sympathetic neurones.
