title: [Interaction between angiotensin II and other local vasoactive substances].
abstract: Recent advances in the molecular characterization for angiotensin II (A II) related to nitric oxide, endothelin-1, prostaglandin, and adrenomedullin are reviewed. A II, the main biological active peptide of the renin-angiotensin system, plays an important role in cardiovascular homeostasis such as regulation of blood pressure and tissue remodeling. A II produces vasoconstriction by a direct action on smooth muscle cells via AT1 receptor. This action can be due to circulating A II but also to A II produced within the tissues. Nitric oxide and adrenomedullin are potent vasorelaxant substances. These substances may play a role as local antimigration factors, and antagonize the effect of A II. Whereas endothelin-1 and thromboxane A2 are vasoconstrictor substances, and may have a role as growth factors. A II and these vasoactive substances mutually exert several biological actions in cardiovascular diseases.
