Publication types Research Support, … WebFeb 4, 2024 · Rationale: Myoendothelial junctions (MEJs) within the fenestrae of the internal elastic lamina (IEL) are critical sites that allow for endothelial cell (EC) - vascular smooth muscle cell (VSMC) contact and communication.
WebIndeed, there is now evidence that the myoendothelial junction serves as a signaling microdomain to organize proteins used to facilitate vascular heterocellular communication. This review highlights the evolving role of myoendothelial junctions in the context of vascular cell-cell communication. ©2014 Int. Union Physiol. Sci./Am. Physiol. Soc. WebMar 1, 2011 · Myoendothelial microdomain signaling via localized calcium-activated potassium channel (KCa) and gap junction connexins (Cx) is critical for endothelium-dependent vasodilation in rat mesenteric artery. The present study determines the relative contribution of NO and gap junction-KCa mediated microdomain signaling to endothelium …

WebOct 12, 2024 · Variation of endothelial gap junction (GJ) calcium signal permeability is a powerful mechanism to modify the response of the endothelium to vasoactive agonists such as histamine or bradykinin. 1, 2 In addition, myoendothelial GJs (MEGJ), that is, GJ between endothelium and smooth muscle cells (SMC) in small vessels, are not only instrumental …
WebSep 15, 2000 · Myoendothelial gap junctions are judged as being present or absent depending on the change in resting membrane potential. Although simple in theory, this approach necessitates the experimenter to identify the cell from which recordings are being obtained and ensure that the modulators of ion channel activity are cell selective.
