Endoplasmic reticulum stress is a mediator of posttransplant injury in severely steatotic liver allografts

Christopher D. Anderson, Gundumi Upadhya, Kendra D. Conzen, Jianlou Jia, Elizabeth M. Brunt, Venkataswarup Tiriveedhi, Yan Xie, Sabarinathan Ramachandran, Thalachallour Mohanakumar, Nicholas O. Davidson, William C. Chapman – 16 November 2010 – Hepatic steatosis continues to present a major challenge in liver transplantation. These organs have been shown to have increased susceptibility to cold ischemia/reperfusion (CIR) injury in comparison with otherwise comparable lean livers; the mechanisms governing this increased susceptibility to CIR injury are not fully understood.

Epidural analgesia provides better pain management after live liver donation: A retrospective study

Hance Clarke, Tony Chandy, Coimbatore Srinivas, Salima Ladak, Nobuhiko Okubo, Nicholas Mitsakakis, Susan Holtzman, David Grant, Stuart A. McCluskey, Joel Katz – 16 November 2010 – Despite the increase in surgical volumes of live liver donation, there has been very little documentation of the postoperative pain experience.

The use of whole organ decellularization for the generation of a vascularized liver organoid

Pedro M. Baptista, Mohummad M. Siddiqui, Genevieve Lozier, Sergio R. Rodriguez, Anthony Atala, Shay Soker – 12 November 2010 – A major roadblock to successful organ bioengineering is the need for a functional vascular network within the engineered tissue. Here, we describe the fabrication of three‐dimensional, naturally derived scaffolds with an intact vascular tree. Livers from different species were perfused with detergent to selectively remove the cellular components of the tissue while preserving the extracellular matrix components and the intact vascular network.

Knockdown of autophagy enhances the innate immune response in hepatitis C virus–infected hepatocytes

Shubham Shrivastava, Amit Raychoudhuri, Robert Steele, Ranjit Ray, Ratna B. Ray – 12 November 2010 – The role of autophagy in disease pathogenesis following viral infection is beginning to be elucidated. We have previously reported that hepatitis C virus (HCV) infection in hepatocytes induces autophagy. However, the biological significance of HCV‐induced autophagy has not been clarified. Autophagy has recently been identified as a novel component of the innate immune system against viral infection.

Interleukin‐28B polymorphisms are associated with histological recurrence and treatment response following liver transplantation in patients with hepatitis C virus infection

Michael R. Charlton, Alexander Thompson, Bart J. Veldt, Kym Watt, Hans Tillmann, John J. Poterucha, Julie K. Heimbach, David Goldstein, John McHutchison – 12 November 2010 – Polymorphism in the interleukin‐28B (IL28B) gene region, encoding interferon (IFN)‐λ3, is strongly predictive of response to antiviral treatment in the nontransplant setting. We sought to determine the prevalence and impact on clinical outcomes of donor and recipient IL28B genotypes among liver transplant recipients.
