TNF-induced liver injury. PG - G387-92 LID - 10.1152/ajpgi.1998.275.3.G387 [doi] AB - Tumor necrosis factor-alpha (TNF-alpha) functions as a two-edged sword in the liver. TNF-alpha is required for normal hepatocyte proliferation during liver regeneration. It functions both as a comitogen and to induce the transcription factor nuclear factor-kappaB, which has antiapoptotic effects. On the other hand, TNF-alpha is the mediator of hepatotoxicity in many animal models, including those involving the toxins concanavalin A and lipopolysaccharide. TNF-alpha has also been implicated as an important pathogenic mediator in patients with alcoholic liver disease and viral hepatitis.
