Enhanced T cell responses against hepatitis C virus by ex vivo targeting of adenoviral particles to dendritic cells

Itziar Echeverria, Alexander Pereboev, Leyre Silva, Aintzane Zabaleta, José Ignacio Riezu‐Boj, Marta Bes, María Cubero, Francisco Borras‐Cuesta, Juan José Lasarte, Juan Ignacio Esteban, Jesús Prieto, Pablo Sarobe – 30 March 2011 – Injection of dendritic cells (DCs) presenting viral proteins constitutes a promising approach to stimulate T cell immunity against hepatitis C virus (HCV). Here we describe a strategy to enhance antigen loading and immunostimulatory functions of DCs useful in the preparation of therapeutic vaccines.

Microglia activation in hepatic encephalopathy in rats and humans

Irina Zemtsova, Boris Görg, Verena Keitel, Hans‐Jürgen Bidmon, Karsten Schrör, Dieter Häussinger – 30 March 2011 – Astrocytes play an important role in the pathogenesis of hepatic encephalopathy (HE) and ammonia toxicity, whereas little is known about microglia and neuroinflammation under these conditions. We therefore studied the effects of ammonia on rat microglia in vitro and in vivo and analyzed markers of neuroinflammation in post mortem brain tissue from patients with cirrhosis with and without HE and non‐cirrhotic controls.

What is the role of the receptor for advanced glycation end products–ligand axis in liver injury?

Giuseppina Basta, Teresa Navarra, Paolo De Simone, Serena Del Turco, Amalia Gastaldelli, Franco Filipponi – 24 March 2011 – Multiligand receptor for advanced glycation end products (RAGE) is expressed in a wide variety of tissues, including the liver. Interactions with its ligands lead to cellular activation and thus prolonged inflammation and apoptosis.

Mixed hepatocellular cholangiocarcinoma and intrahepatic cholangiocarcinoma in patients undergoing transplantation for hepatocellular carcinoma

Gonzalo Sapisochin, Nicholas Fidelman, John P. Roberts, Francis Y. Yao – 24 March 2011 – Mixed hepatocellular cholangiocarcinoma (HCC‐CC) and intrahepatic cholangiocarcinoma (I‐CC) are increasingly being reported in patients with cirrhosis.
