    Direct immunofluorescence studies were performed on isolated liver cells in order to detect surface localisation of IgG in acute and chronic hepatitis and primary biliary cirrhosis. Membrane-bound IgG was demonstrated in nine patients. Six of eight patients with primary biliary cirrhosis showed granular fluorescence on their liver cell surfaces suggesting that an antibody or immune complex-mediated cytotoxicity might be involved in the pathogenesis of this disease.
