Liver transplantation in transthyretin amyloidosis: Issues and challenges

Andreia Carvalho, Ana Rocha, Luísa Lobato – 6 December 2014 – Hereditary transthyretin amyloidosis (ATTR) is a rare worldwide autosomal dominant disease caused by the systemic deposition of an amyloidogenic variant of transthyretin (TTR), which is usually derived from a single amino acid substitution in the TTR gene. More than 100 mutations have been described, with V30M being the most prevalent. Each variant has a different involvement, although peripheral neuropathy and cardiomyopathy are the most common.

Hepatitis C virus–induced reduction in miR‐181a impairs CD4+ T‐cell responses through overexpression of DUSP6

Guang Y. Li, Yun Zhou, Ruo S. Ying, Lei Shi, Yong Q. Cheng, Jun P. Ren, Jeddidiah W.D. Griffin, Zhan S. Jia, Chuan F. Li, Jonathan P. Moorman, Zhi Q. Yao – 5 December 2014 – T cells play a crucial role in viral clearance or persistence; however, the precise mechanisms that control their responses during viral infection remain incompletely understood. MicroRNA (miR) has been implicated as a key regulator controlling diverse biological processes through posttranscriptional repression.

Autoimmune hepatitis in a murine autoimmune polyendocrine syndrome type 1 model is directed against multiple autoantigens

Matthias Hardtke‐Wolenski, Richard Taubert, Fatih Noyan, Maren Sievers, Janine Dywicki, Jerome Schlue, Christine S. Falk, Brita Ardesjö Lundgren, Hamish S. Scott, Andreas Pich, Mark S. Anderson, Michael P. Manns, Elmar Jaeckel – 5 December 2014 – Autoimmune polyendocrine syndrome type 1 (APS‐1) is caused by mutations of the autoimmune regulator (AIRE) gene. Mouse studies have shown that this results in defective negative selection of T cells and defective early seeding of peripheral organs with regulatory T cells (Tregs).
