Hydrogen peroxide signaling in vascular endothelial cells

Redox signaling is implicated in different physiological and pathological events in the vasculature. Among the different reactive oxygen species, hydrogen peroxide (H2O2) is a very good candidate to perform functions as an intracellular messenger in the regulation of several biological events.In this review, we summarize the main physiological sources of H2O2 in the endothelium and the molecular mechanisms by which it is able to act as a signaling mediator in the vasculature.
