Abstract:In resistance arteries, smooth muscle cells (SMCs) and endothelial cells (ECs) are communicated through gap junctions (i.e. myoendothelial gap junctions), which provide a signaling pathway for control of vasomotor tone. In this context, the Ca2+ signaling associated to smooth muscle contraction might also be transmitted via myoendothelial gap junctions and activate a regulatory feedback mechanism (myoendothelial feedback) by the production of endothelium‐dependent vasodilators. It is thought that IP3 is the ma… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
