Gap junctions are intercellular channels that allow diffusion of small solutes and ions between adjoining cells. This intercellular exchange enables intercellular communication of specific signals and metabolic products that promote coordination of multicellular function. In blood vessels, gap junctions have been implicated in such diverse functions as regulation of vascular tone, transendothelial cell migration, and the pathogenesis of atherosclerosis. Here we focus on some essential principles of gap junctional function in the vascular bed.
