OBJECTIVE IGF-1 and the IGF-1 receptor (IGF-1R) have been implicated in the regulation of adipocyte differentiation and lipid accumulation in vitro. RESEARCH DESIGN AND METHODS To investigate the role of IGF-1 receptor in vivo, we have inactivated the Igf-1r gene in adipose tissue (IGF-1R(aP2Cre) mice) using conditional gene targeting strategies.

F-actin bundling plastin 3 (PLS3) is a fully protective modifier of the neuromuscular disease spinal muscular atrophy (SMA), the most common genetic cause of infant death. The generation of a conditional PLS3-over-expressing mouse and its breeding into an SMA background allowed us to decipher the exact biological mechanism underlying PLS3-mediated SMA(More)
The microbiota is pivotal in the pathogenesis of inflammatory bowel disease (IBD)-associated inflammation-induced colorectal cancer (CRC), yet mechanisms for these effects remain poorly characterized. Here, we demonstrate that aberrant inflammasome-induced microbiota plays a critical role in CRC development, where mice deficient in the NOD-like receptor(More)
Reactive oxygen species (ROS) produced by NADPH oxidase function as defence and signalling molecules related to innate immunity and various cellular responses. The activation of NADPH oxidase in response to plasma membrane receptor activation depends on the phosphorylation of cytoplasmic oxidase subunits, their translocation to membranes and the assembly of(More)
Loss of appetite is a hallmark of inflammatory diseases. The underlying mechanisms remain undefined, but it is known that myeloid differentiation primary response gene 88 (MyD88), an adaptor protein critical for Toll-like and IL-1 receptor family signaling, is involved. Here we addressed the question of determining in which cells the MyD88 signaling that(More)
The cellular sources of interleukin 6 (IL-6) that are relevant for differentiation of the TH17 subset of helper T cells remain unclear. Here we used a novel strategy for the conditional deletion of distinct IL-6-producing cell types to show that dendritic cells (DCs) positive for the signaling regulator Sirpα were essential for the generation of pathogenic(More)
CYLD was originally identified as a tumor suppressor gene mutated in familial cylindromatosis, an autosomal dominant predisposition to multiple benign neoplasms of the skin known as cylindromas. The CYLD protein is a deubiquitinating enzyme that acts as a negative regulator of NF-κB and JNK signaling through its interaction with NEMO and TNFR-associated(More)
19 patients were treated via a tumour prosthesis in the hip joint region. The indication resulted from osteolyses, loosening of prosthesis and subtrochanteric fractures in aged patients involving risk factors. The results show that application of a tumour prosthesis is a suitable method for bridging over major defects in the proximal femur to achieve early(More)
Epstein-Barr virus (EBV) is a γ herpes virus endemic in humans and transforming human B lymphocytes. It causes a variety of human pathologies ranging from infectious mononucleosis upon acute infection to EBV-driven B-cell lymphomas. In humans, EBV-infected cells are under powerful immune surveillance by T and NK cells. If this immune surveillance is(More)
