Membrane potential governs calcium influx into microvascular endothelium: integral role for muscarinic receptor activation

Key points Endothelial function in resistance vessels entails Ca2+ and electrical signalling to promote vasodilatation and increase tissue blood flow. Whether membrane potential (Vm) governs intracellular calcium concentration ([Ca2+]i) of the endothelium remains controversial. [Ca2+]i and Vm were e...
