Fig. 4From: Sulphite oxidase (SO) – a mitochondrial autoantigen as target for humoral and cellular immune reactions in primary sclerosing cholangitisProliferative response of peripheral blood mononuclear cells from 33 PSC patients and 10 healthy individuals towards the four SO-proteins SO-fl, SO-I, SO-II, SO-III as measured by lymphocyte transformation test (cpm = counts per minute). Sp = spontaneous proliferation without antigen. Significance levels as compared to the spontaneous proliferation are indicated. Significance as compared to PSC-patients: * p < 0.05; ** p < 0.01; *** p < 0.001Back to article page
