Isoprostanes are marker of lipid peroxidation and are produced after free-radical attack of membrane lipids. In addition, they are biologically active and are essentially vaso- and broncho-constrictor. Their smooth muscle constrictor actions are closely linked to the activation of the thromboxane A2 receptor, but also involve a distinct receptor not yet identified. The response of vascular smooth muscle to isoprostanes is subclass-specific (F-series versus E-series isoprostanes) and cell- and species-related. In this review, we will address the vascular actions of isoprostanes and their possible role in vascular physiology and pathophysiology.
