Abstract

The present study suggests that CGRP possesses multiple effects on various ionic channels. Among them the effects on potassium currents are major determinants in the changes in action potential induced by CGRP under physiological temperature. It is necessary to further study the influences of CGRP on different types of potassium channels.
