Amplification of EDHF‐type vasodilatations in TRPC1‐deficient mice

Abstract

Our data demonstrate that TRPC1 acts as a negative regulator of endothelial K(Ca) channel-dependent EDHF-type vasodilatations and thereby contributes to blood pressure regulation. Thus, we propose a specific role of TRPC1 in the EDHF-K(Ca) signalling complex and suggest that pharmacological inhibition of TRPC1, by enhancing EDHF vasodilatations, may be a novel strategy for lowering blood pressure.
