Recruitment of Dynamic Endothelial <scp><scp>Ca</scp></scp>²⁺ Signals by the <scp>TRPA</scp>1 Channel Activator <scp>AITC</scp> in Rat Cerebral Arteries

Abstract

Our findings indicate that factors that stimulate TRPA1 channels expand Ca2+ signal-effector coupling at discrete sites along the endothelium to evoke graded cerebral artery vasodilation.
