Abstrakt: Background: The mechanism by which alcohol induces alcoholic hepatitis, the precursor lesion for cirrhosis, has never been elucidated. In particular, direct toxicity has not been proven. This article reviews the hypothesis that a primary target of chronic alcohol ingestion is the T lymphocyte. The lesion in the T lymphocyte is characterized by reduced baseline secretion of cytokines, including tumor necrosis factor‐α; although characterized by an exaggerated release of cytokines when stimulated by polyclonal activators such as endotoxin. High concentrations of cytokines, especially tumor necrosis factor‐α, within the liver induce necrosis/apoptosis of hepatocytes.
