Adaptation of the hepatitis B virus core protein to CD8+ T‐cell selection pressure

Helenie Kefalakes, Bettina Budeus, Andreas Walker, Christoph Jochum, Gudrun Hilgard, Andreas Heinold, Falko M. Heinemann, Guido Gerken, Daniel Hoffmann, Joerg Timm – 26 February 2015 – Activation of hepatitis B virus (HBV)–specific CD8 T cells by therapeutic vaccination may promote sustained control of viral replication by clearance of covalently closed circular DNA from infected hepatocytes. However, little is known about the exact targets of the CD8 T‐cell response and whether HBV reproducibly evades CD8 T‐cell immune pressure by mutation.

Toward a more complete understanding of the association between a hepatitis C sustained viral response and cause‐specific outcomes

Hamish A. Innes, Scott A. McDonald, John F. Dillon, Sam Allen, Peter C. Hayes, David Goldberg, Peter R. Mills, Stephen T. Barclay, David Wilks, Heather Valerio, Ray Fox, Diptendu Bhattacharyya, Nicholas Kennedy, Judith Morris, Andrew Fraser, Adrian J. Stanley, Peter Bramley, Sharon J. Hutchinson – 26 February 2015 – Sustained viral response (SVR) is the optimal outcome of hepatitis C virus (HCV) therapy, yet more detailed data are required to confirm its clinical value. Individuals receiving treatment in 1996‐2011 were identified using the Scottish HCV clinical database.

Targeted pharmacotherapy in progressive familial intrahepatic cholestasis type 2: Evidence for improvement of cholestasis with 4‐phenylbutyrate

Emmanuel Gonzales, Brigitte Grosse, Brice Schuller, Anne Davit‐Spraul, Filomena Conti, Catherine Guettier, Doris Cassio, Emmanuel Jacquemin – 26 February 2015 – Progressive familial intrahepatic cholestasis type 2 (PFIC2) is a result of mutations in ABCB11 encoding bile salt export pump (BSEP), the canalicular bile salt export pump of hepatocyte. In some PFIC2 patients with missense mutations, BSEP is not detected at the canaliculus owing to mistrafficking of BSEP mutants. In vitro, chaperone drugs, such as 4‐phenylbutyrate (4‐PB), have been shown to partially correct mistrafficking.
