title: Lymphocyte subsets studied with monoclonal antibodies in liver tissues of patients with alcoholic liver disease.
abstract: In order to determine the nature of T lymphocytes accumulating in hepatic tissues of patients with alcoholic liver disease, we phenotyped these cells in situ, using monoclonal antibodies to lymphocyte surface antigens and the avidin-biotin-peroxidase complex (ABC) technique. In portal areas of cirrhotic livers, a significant increase (p less than 0.001) in T lymphocytes was observed as compared to livers showing only fatty changes and normal liver tissues. The T cells accumulating in cirrhotic livers comprised T helper-inducer (T4) and T suppressor-cytotoxic (T8) subsets with the T4/T8 ratio of 1.4 +/- 0.5 (SD, n = 14). In contrast, the T lymphocytes in the cellular projections which extended into the parenchyma consisted mostly of suppressor-cytotoxic cells. The relative enrichment in T8+ lymphocytes among the cells invading the parenchyma suggests that they may be important in the mediation of a cytotoxic injury of hepatocytes in advanced alcoholic liver disease and in regulating an immunologic challenge possibly initiated in response to alcoholic hyaline.
