Delivery of antioxidative enzyme genes protects against ischemia/reperfusion–induced liver injury in mice

Song‐Qing He, Yan‐Hong Zhang, Senthil K. Venugopal, Christopher W. Dicus, Richard V. Perez, Rajen Ramsamooj, Michael H. Nantz, Mark A. Zern, Jian Wu – 28 November 2006 – Hepatic ischemia/reperfusion (I/R) injury is characterized by the generation of reactive oxygen species (ROS), such as superoxide anions and hydrogen peroxide. The aim of this study is to investigate whether antioxidative gene delivery by our polylipid nanoparticles (PLNP) is an effective approach for prevention of the injury.

Conversion to sirolimus: A useful strategy for recalcitrant cutaneous viral warts in liver transplant recipient

Sébastien Dharancy, Benoît Catteau, Laurent Mortier, Emmanuel Boleslawski, Nicole Declerck, Valérie Canva, Frédéric Piette, Philippe Mathurin, François René Pruvot – 28 November 2006 – Dermatological complications following transplantation are very common and the majority of immunosuppressed transplant recipients develop some to many warts due to human papillomavirus (HPV) infection. In the setting of immunosuppression, therapeutic management may be disappointing because of the extent of the lesions in patients unable to develop a sufficient immune response directed against HPV.

Relative adrenal insufficiency manifested with multiple organ dysfunction in a liver transplant patient

Takeshi Iwasaki, Masahiro Tominaga, Takumi Fukumoto, Nobuya Kusunoki, Takemi Sugimoto, Masahiro Kido, Satoshi Ogata, Atsushi Takebe, Motofumi Tanaka, Yonson Ku – 28 November 2006 – Relative adrenal insufficiency is now a well‐known clinical condition that occurs in critically ill patients particularly with septic complication. However, this pathology has long been unrecognized until recently in liver transplantation patients, for whom postoperative immunosuppressive therapies almost always comprise corticosteroids.

In vivo expansion of two distinct dendritic cells in mouse livers and its impact on liver immune regulation

Yalan Wang, Ning Zheng, Zhengbin Lu, Wenhan Wu, Lianfu Wang, Atsunori Nakao, Michael T. Lotze, Carrie E. Langer, John J. Fung, Shiguang Qian, Lina Lu – 28 November 2006 – Liver transplant tolerance in pigs, rats, and mice has been disclosed for decades, but the underlying mechanisms are not completely understood. Accumulating data indicate that residing dendritic cells (DC) are important in determining direction of immune responses in the liver. However, our knowledge remains very limited due to the difficulties in obtaining sufficient liver DC.

IP‐10 predicts viral response and therapeutic outcome in difficult‐to‐treat patients with HCV genotype 1 infection

Martin Lagging, Ana I. Romero, Johan Westin, Gunnar Norkrans, Amar P. Dhillon, Jean‐Michel Pawlotsky, Stefan Zeuzem, Michael von Wagner, Francesco Negro, Solko W. Schalm, Bart L. Haagmans, Carlo Ferrari, Gabriele Missale, Avidan U. Neumann, Elke Verheij‐Hart, Kristoffer Hellstrand, DITTO‐HCV Study Group – 28 November 2006 – Plasma from 173 patients with HCV genotype 1 infection was analyzed for IP‐10 levels prior to treatment with pegylated interferon‐α‐2a and ribavirin.
