Autoantibody against liver cell membrane and killer cell activity in chronic liver diseases.
The aim of our present study was to examine the ADCC reaction against liver cell in various chronic liver diseases on the basis of indirect evidence. Forty-nine liver patients and one hundred and twenty-three healthy controls were examined. Anti-LSP autoantibody was determined on rat liver membrane by using the indirect immunofluorescent method. On the other hand, Killer-cell activity against human erythrocyte target cells was established in the lymphocytes of peripheral blood. Anti-LSP autoantibodies were demonstrated in seven patients and were associated with the high Killer-cell activity in six cases. Specific ADCC reaction to liver cell membrane can be assumed if anti-LSP autoantibody presence is topped with increased Killer-cell activity.
