ABSTRACT
Antibody to the hepatocyte membrane protein, was induced in inbred strain C57BL/6 and C3H mice by immunisation with 100,000 g supernatant of syngeneic liver homogenate in CFA. Three weekly intraperitoneal injection of 200 ul of liver homogenate with CFA for continuous 4 weeks gave the best possible result. Histopathological changes were characterised mainly by perivascular inflammatory infiltrates and hepatocyte necrosis which mimicked human autoimmune hepatitis. In one of the immunological parameters, antibody to hepatocyte membrane protein (LSP) has been demonstrate by ouchterlony method in the test serum of those animals, who had received weekly doses of liver antigen. Thus in experimental autoimmune liver disease, semi-purified syngeneic liver fluid (S-100) leads to hepatic destruction and to an inflammatory process with several features in common with human chronic aggressive hepatitis. The presence of antibody against syngeneic liver antigen (S-100) in the test sera emphasizes that hepatocyte membrane protein does have an important role in liver tissue pathogenesis and disease process in experimental model. In this study we tried to prove that hepatocyte membrane protein may act as a target antigen in developing experimental autoimmune hepatitis.
