Host cell responses induced by hepatitis C virus binding

Xinhua Fang, Mirjam B. Zeisel, Jochen Wilpert, Bettina Gissler, Robert Thimme, Clemens Kreutz, Thomas Maiwald, Jens Timmer, Winfried V. Kern, Johannes Donauer, Marcel Geyer, Gerd Walz, Erik Depla, Fritz von Weizsäcker, Hubert E. Blum, Thomas F. Baumert – 25 May 2006 – Initiation of hepatitis C virus (HCV) infection is mediated by docking of the viral envelope to the hepatocyte cell surface membrane followed by entry of the virus into the host cell.

Ethical, social and legal implications of genetic testing in liver disease

Dirk J. van Leeuwen, James L. Bernat – 25 May 2006 – Advances in molecular genetics challenge the hepatology community to understand and implement genetic knowledge. Despite excitement about the potential benefits of new genetic information, concerns have been raised about the inappropriate use of genetic testing, clinicians' incorrect ordering and misinterpretation of test results, and discrimination in employment and insurability based on tests results.

Brain edema and inflammatory activation in bile duct ligated rats with diet‐induced hyperammonemia: A model of hepatic encephalopathy in cirrhosis

Rodrigo Jover, Regina Rodrigo, Vicente Felipo, Ricardo Insausti, Javier Sáez‐Valero, M. Salud García‐Ayllón, Isabel Suárez, Asunción Candela, Antonio Compañ, Angel Esteban, Omar Cauli, Eva Ausó, Erika Rodríguez, Ana Gutiérrez, Eva Girona, Slaven Erceg, Pere Berbel, Miguel Pérez‐Mateo – 25 May 2006 – Studies of the pathogenesis of hepatic encephalopathy are hampered by the lack of a satisfactory animal model. We examined the neurological features of rats after bile duct ligation fed a hyperammonemic diet (BDL+HD).

Impact of obesity on treatment of chronic hepatitis C

Michael R. Charlton, Paul J. Pockros, Stephen A. Harrison – 25 May 2006 – Obesity and the metabolic syndrome have hepatic manifestations, including steatosis and progression of fibrosis. In individuals with chronic hepatitis C, obesity is associated with inflammation, insulin resistance, steatosis, progression of fibrosis, and nonresponse to treatment with interferon or peginterferon alpha and ribavirin. Patients with both hepatitis C and obesity‐related nonalcoholic fatty liver disease are at greater risk for more advanced liver disease.

Anti‐HCV therapies in chimeric scid‐Alb/uPA mice parallel outcomes in human clinical application

Norman M. Kneteman, Amy J. Weiner, John O'Connell, Marc Collett, Tiejun Gao, Lea Aukerman, Rosemary Kovelsky, Zhi‐Jie Ni, Ahmad Hashash, Janine Kline, Belinda Hsi, Daniel Schiller, Donna Douglas, D Lorne J Tyrrell, David F. Mercer – 25 May 2006 – Compounds with in vitro anti‐hepatitis C virus (HCV) activity are often advanced directly into clinical trials with limited or no in vivo efficacy data. This limits prediction of clinical efficacy of compounds in the HCV drug pipeline, and may expose human subjects to unnecessary treatment effects.

Hepatocytes as cytotoxic effector cells can induce cell death by CD95 ligand‐mediated pathway

Clifford S. Guy, Jinguo Wang, Tomasz I. Michalak – 25 May 2006 – The liver plays an increasingly recognized role in the host's immune responses. The direct contribution of hepatocytes as effector cells to local immunity, pathogen containment, and liver disease is not determined. This in vitro study examined whether hepatocytes can eliminate other cells via a CD95 ligand (CD95L or FasL)/CD95 (Fas)–mediated mechanism and whether this cytotoxic activity can be modulated by cytokines such as interferon gamma (IFN‐γ) or tumor necrosis factor alpha (TNF‐α).
