Arginase, an enzyme within the urea cycle in the liver, is also found in many other cells and tissues, including the lung. Arginase is present in 2 isoforms: arginase I, the hepatic isoform; and arginase II, the extrahepatic isoform; each of which is encoded by a distinct gene.

The expression and function of arginase I in macrophages, hepatocytes, and vascular smooth muscle cells, is stimulated by lipopolysaccharide (LPS), IL-13, altered oxygen tension, and balloon dilatation of coronary arteries. The activation and expression of endothelial arginase II can also be induced by a variety of vascular insults.

Arginase competitively inhibits nitric oxide synthase (NOS) via use of the common substrate L-arginine. Inhibition of arginase activity enhances a variety of parameters relevant to allergic airways disease, possibly by altering NO homeostasis. Arginase inhibition actively augments NO production and has beneficial effects on normal cardiac function and on vascular dysfunction typical of atherogenesis, aging, and erectile dysfunction, and sickle cell disease.
