HLA variants related to primary sclerosing cholangitis influence rejection after liver transplantation

Figure 1 Immunoenzyme stainings in a liver biopsy from a transplanted primary sclerosing cholangitis patient with acute cellular rejection scored according to the Banff criteria as RAI 5 (panels A-C), and from a transplanted control patient (secondary liver metastases) with the same grade of cellular rejection (panels D-F). Panels A and D show double immunoenzyme staining for CD3 (red) and CD56 (brown, arrows) in a portal area. Panels B and E show immunoperoxidase staining for CD57 (brown, arrows) in a portal area. Panels C and F show CD56-staining of bile ducts (arrows). Only scattered CD56- and CD57 positive leucocytes can been seen in both patients (Original magnification × 400).
