Comparison of the level of CD86+ LIMC and clinical data in patients with AIH (18 cases) and fatty liver (2 cases). LIMCs taken from the liver biopsy specimen of patients with AIH (18 cases) and 2 patients with fatty liver were stained with antibody against CD86 and analyzed by using flow cytometry. Three thousand events were acquired for each analysis. Patients with AIH showed high levels of CD86+ LIMC irrespective of the levels of γ-globulin, ALT, histological activity, and the presence or absence of the administration of corticosteroids (CS). Response to CS in patients with AIH was shown to be associated with the level of CD86+ LIMC. NT: not tested.
