โœฆ Synopsis


Using monoclonal antibodies to surface antigens, we typed and quantitated the mononuclear cells (MNCs) infiltrating liver tissues from 23 patients with primary sclerosing cholangitis. The circulating T lymphocytes were also enumerated by flow cytometry in 12 of these patients. In blood, T lymphocytes and especially T8+ cells were decreased. T cells were the major components of MNCs (78%) in portal tracts. Few of these cells were Tac+ or HLA-DR+. Total MNCs (929 & 90 vs. 106 & 18 in controls) included 11% M1+ and 8% B1+ cells. Aggregates of T4+ and T8+ cells were common in portal areas. The portal T4/TS ratio of 1.27 2 0.1 was significantly (p <
