Nitric oxide (NO) is formed in the endothelium by the constitutive enzyme NO synthase from the substrate amino acid L-arginine. As an endogenous vasodilator it contributes to renal arteriolar tone and modulates relaxation of the mesangium, thus contributing to regulation of glomerular microcirculation. NO also plays a role in regulating renal sodium excretion and renin release. It has antiplatelet and antithrombogenic effects and thus helps prevent thrombosis within the glomerular capillaries. In sepsis and sepsis-related syndromes, NO has a renoprotective role in that it aids in maintaining renal vasodilation and inhibiting platelet adhesion and aggregation. More knowledge of these effects may lead to the design of therapeutic interventions for preventing glomerular injury.
