BACKGROUND The endoplasmic reticulum (ER) is the cellular site for protein folding. ER stress occurs when protein folding capacity is exceeded. This stress induces a cyto-protective signaling cascades termed the unfolded protein response (UPR) aimed at restoring homeostasis. While acute ER stress is lethal, chronic sub-lethal ER stress causes cells to adapt(More)
Nonalcoholic fatty liver disease (NAFLD) is a leading cause of liver disease in developed countries. Its frequency is increasing in the general population mostly due to the widespread occurrence of obesity and the metabolic syndrome. Although drugs and dietary supplements are viewed as a major cause of acute liver injury, drug induced steatosis and(More)
T lymphocyte-expressing natural killer (NK) cell markers (NKT cells) play a role in immune regulation. Our aim was to evaluate the in vivo effect of adoptive transfer of immune-programmed NKT cells. Colitis was induced in C57/B6 mice by 2,4,6-trinitrobenzenesulfonic acid. NKT, CD4, CD8 lymphocytes, and dendritic cells (DC) were prepared from spleens of(More)
BACKGROUND AND AIMS C/EBP homologous protein (CHOP) plays pro-apoptotic roles in the integrated stress response. Recently, a tumor suppressive role for CHOP was demonstrated in lung cancer via regulation of tumor metabolism. To explore the role of CHOP in hepatocarcinogenesis, we induced hepatocellular carcinoma (HCC) in wild type (wt) and CHOP knockout(More)
AIM To assess the practice of caring for acute liver failure (ALF) patients in varying geographic locations and medical centers. METHODS Members of the European Acute Liver Failure Consortium completed an 88-item questionnaire detailing management of ALF. Responses from 22 transplantation centers in 11 countries were analyzed, treating between 300 and 500(More)
BACKGROUND Non-alcoholic fatty liver (NAFLD) is a common, multi-factorial, and poorly understood liver disease whose incidence is globally rising. NAFLD is generally asymptomatic and associated with other manifestations of the metabolic syndrome. Yet, up to 25% of NAFLD patients develop a progressive inflammatory liver disease termed non-alcoholic(More)
