Immunotoxicology: role of inflammation in chemical-induced hepatotoxicity

Abstract

The liver, which is the major organ responsible for the metabolism of drugs and chemicals, is also the primary target organ for many toxic chemicals. Increasing evidence has indicated that inflammatory processes are intimately involved in chemical-induced hepatotoxic processes, and like other inflammatory diseases, such as autoimmunity, are responsible for producing mediators which can effect liver damage or repair. This review will summarize the authors' current understanding of how inflammatory processes influence hepatic pathology and repair following exposure to established hepatotoxic chemicals including carbon tetrachloride (CCl4), an industrial chemical, and acetaminophen (APAP), a widely used analgesic.
