Apoptotic cells attenuate fulminant hepatitis by priming Kupffer cells to produce interleukin‐10 through membrane‐bound TGF‐β

Minggang Zhang, Sheng Xu, Yanmei Han, Xuetao Cao – 6 October 2010 – The liver, a unique tolerogenic organ, is regarded as the site to trap and destroy aging erythrocytes and activated T cells. However, to date, the mechanisms for why the liver is tolerogenic and whether liver Kupffer cells (KC) are critical phagocytes for apoptotic cells (AC) contributing to the liver immunosuppression remain unclear. Here we report that KC is the main phagocyte for AC in the liver.

Noninvasive assessment of liver fibrosis

Stella M. Martínez, Gonzalo Crespo, Miquel Navasa, Xavier Forns – 30 September 2010 – Liver biopsy has long been an important tool for assessing the degree of liver fibrosis. Information on the presence and degree of liver fibrosis is useful before making therapeutic decisions or predicting disease outcomes. The need to stage liver fibrosis, however, should decrease as treatment options become more successful (as has occurred with viral hepatitis).

MicroRNA silencing of tumor suppressor DLC‐1 promotes efficient hepatitis C virus replication in primary human hepatocytes

Krishna Banaudha, Michael Kaliszewski, Tamara Korolnek, Liliana Florea, Man Lung Yeung, Kuan‐Teh Jeang, Ajit Kumar – 30 September 2010 – MicroRNAs (miRNAs) are approximately 22‐nucleotide noncoding RNAs that constitute silencers of target gene expression. Aberrant expression of miRNA has been linked to a variety of cancers, including hepatocellular carcinoma (HCC). Hepatitis C virus (HCV) infection is considered a major cause of chronic liver disease and HCC, although the mechanism of virus infection–associated hepatocarcinogenesis remains unclear.

Importance of hepatic fibrosis in cystic fibrosis and the predictive value of liver biopsy

Peter J. Lewindon, Ross W. Shepherd, Meagan J. Walsh, Ristan M. Greer, Richard Williamson, Tamara N. Pereira, Kieran Frawley, Scott C. Bell, Jeffery L. Smith, Grant A. Ramm – 30 September 2010 – Cystic fibrosis liver disease (CFLD), which results from progressive hepatobiliary fibrosis, is an important cause of morbidity and mortality, but it is difficult to identify before portal hypertension (PHT) ensues.
