The adipose tissue has recently emerged as an important endocrine organ releasing numerous mediators including adipocytokines, classical cytokines and others. Adiponectin, one of the major products of adipocytes, is a prototypic anti-diabetic adipocytokine, the actions of which are mainly exerted by the activation of AMP-activated kinase and peroxisome(More)
BACKGROUND & AIMS Alcoholic steatohepatitis (ASH) is characterised by neutrophil infiltration that contributes to hepatic injury and disease. Lipocalin-2 (LCN2) was originally identified as siderophore binding peptide in neutrophils, which exerted tissue protective effects in several disease models. Here we investigate the role of LCN2 in the pathogenesis(More)
Diseases of the liver and the biliary tract are commonly observed in patients with inflammatory bowel diseases (IBD). Besides primary sclerosing cholangitis (PSC), drug-induced hepatotoxicity and non-alcoholic fatty liver disease (NAFLD) are the most frequent liver complications in IBD. PSC is a chronic inflammatory and commonly progressive disorder of(More)
Potent and safe vaccinia virus vectors inducing cell-mediated immunity are needed for clinical use. Replicating vaccinia viruses generally induce strong cell-mediated immunity; however, they may have severe adverse effects. As a vector for clinical use, we assessed the defective vaccinia virus system, in which deletion of an essential gene blocks viral(More)
Obesity and obesity-related disorders have dramatically increased globally in the last decades. These entities are commonly associated with a state of insulin resistance and the relationship between extensive lipid deposition and insulin resistance is widely accepted. The underlying mechanisms for insulin resistance, however, are still incompletely(More)
Adipocytokines are primarily adipocyte-derived products, although certain members are also synthesized by other cell types. These adipocytokines, similarly to classical cytokines, are characterized by very pleiotropic functions affecting biological processes throughout the body. An increasing number of adipocytokines has recently been recognized, such as(More)
Dietary factors and the associated lifestyle play a major role in the pathophysiology of many diseases. Several diets, especially a Western lifestyle with a high consumption of meat and carbohydrates and a low consumption of vegetables, have been linked to common diseases, such as metabolic syndrome, atherosclerosis, inflammatory bowel diseases, and colon(More)
The innate immune system and its major mediators, i.e., cytokines, are increasingly recognized as being of crucial importance in metabolic inflammation as observed in morbid obesity and type 2 diabetes (T2D). Morbid obesity is commonly associated with adipose tissue inflammation. Adipose tissue inflammation is characterized by an increased expression of(More)
We report the rescue of a defective vaccinia virus, forming the basis for a stringent selection protocol to generate replicating recombinant virus without the need for marker cassettes and selection agents. Plaques of recombinant virus could be isolated solely by their ability to grow in wild-type cells normally supporting the growth of vaccinia virus. All(More)
BACKGROUND & AIMS Severe obesity is associated with a state of chronic inflammation. Sirtuins (SIRT) are a family of conserved enzymes which are able to affect many metabolic and inflammatory pathways thereby potentially improving health and increasing lifespan. METHODS We investigated the effect of weight loss on subcutaneous adipose tissue and liver(More)
