Summary
Carbon monoxide (CO) is synthesized in vivo by heme oxygenase (HO). Recent studies suggest that the liver utilizes this gas to relax its microvessels such as sinusoids and to thereby maintain low vascular resistance. CO seems to be released mainly from hepatocytes that express HO-2, the constitutive enzyme, and also HO-1, induced under stress conditions. CO released into the space of Disse accesses the hepatic stellate cells, which express soluble guanylate cyclase as a gas signal transducer, although whether this heme protein serves as an authentic receptor for CO remains unknown. This chapter focuses on recent developments, collected from both experimental and clinical settings, regarding both the physiologic and pathophysiologic roles of CO as a regulator of hepatobiliary functions.
