Martin Volkmann, Martina Müller, Walter J. Hofmann, Martina Meyer, Jens Hagelstein, Ulrich Räth, Burkhard Kommerell, Hanswalter Zentgraf, Peter R. Galle – 1 September 1993 – Recently, p53 gene aberrations have been recognized as a relevant factor in hepatocarcinogenesis, in tumors from both high‐risk and low‐risk areas. Because p53 gene mutations typically result in increased p53 levels in tumor cells, this cellular protein might become immunogenic during tumor development.

Marcus K. H. Auth, Raymond A. Keitzer, Martin Scholz, Roman A. Blaheta, E. Christoph Hottenrott, Günther Herrmann, Albrecht Encke, Bernd H. Markus – 1 September 1993 – Biliary epithelial cells are a primary site of damage in liver allograft rejection and in immunologically mediated diseases such as primary biliary cirrhosis. Human leukocyte antigens and adhesion molecules on the biliary epithelium are associated with T‐lymphocytic binding, recognition and destruction.

Tadashi Terada, Yasuni Nakanuma – 1 September 1993 – We investigated the development of human intrahepatic peribiliary capillary plexus by lectin‐histochemistry and immunohistochemistry, using 40 fetal livers of various gestational ages, 52 postnatal livers of various ages, and 10 adult livers.

Anna S. F. Lok, David Chien, Qui‐Lim Choo, Tak‐Mao Chan, Edmond K. W. Chiu, Ignatius K. P. Cheng, Michael Houghton, George Kuo – 1 September 1993 – Some immunosuppressed patients with hepatitis C virus infection do not have detectable levels of antibody to hepatitis C virus on second‐generation enzyme immunoassay. Antibodies to the envelope and nonstructural region 5 proteins have not been examined.

Fabio Tarsetti, Renato Lenzi, Roberto Salvi, Ekkehard Schuler, Koshilya Rijhsinghani, Romana Lenzen, Nicola Tavoloni – 1 September 1993 – In an attempt to clarify the role of oval cells in the emergence of hepatocellular carcinoma, we fed rats a choline‐free diet containing 0%, 0.05% or 0.1% ethionine. The incidence and nature of premalignant and malignant hepatic lesions were then related to the degree of oval cell proliferation.

Gabriele Missale, John J. Brems, Howard Takiff, Paul J. Pockros, Francis V. Chisari – 1 September 1993 – The proliferative response of peripheral blood lymphocytes to the HBcAg was compared with serological, molecular and immunohistochemical parameters of hepatitis B virus infection and with biochemical and histological parameters of liver disease in a patient who received a completely human leukocyte antigen class I‐mismatched liver allograft for fulminant hepatitis.

Jorge J. Gumucio, W. Michael McDonnell – 1 September 1993 – Cytotoxic T lymphocytes (CTLs) specific for conserved viral antigens can respond to different strains of virus, in contrast to antibodies, which are generally strain‐specific. The generation of such CTLs in vivo usually requires endogenous expression of the antigen, as occurs in the case of virus infection.

Faye D. Roberts, Paul Charalambous, Linda Fletcher, Lawrie W. Powell, June W. Halliday – 1 September 1993 – The pathogenesis of hepatic fibrosis and cirrhosis in genetic hemochromatosis may involve a direct effect of excess iron on collagen synthesis in the liver. To investigate this theory, we measured procollagen messenger RNA levels (types I, III and IV) in the livers of rats in which we produced chronic parenchymal iron overload by feeding them dietary carbonyl iron (2.5%, wt/wt) for up to 18 mo.

Sebastiaan Esbach, Moniek N. Pieters, Johannes Van Der Boom, Donald Schouten, M. Niels Van Der Heyde, Paul J. M. Roholl, Adriaan Brouwer, Theo J. C. Van Berkel, Dick L. Knook – 1 September 1993 – The interaction of oxidized human low‐density lipoproteins with human and rat liver was analyzed by light and electron microscopy.
