Cytotoxicity, Accumulation and Translocation of Silver and Silver Sulfide Nanoparticles in contact with Rainbow Trout Intestinal Cells

Kristin Schirmer

Silver nanoparticles (Ag NPs) are widely used in consumer products especially because of their antimicrobial properties. However, this wide usage of Ag NPs is accompanied by their release into the environment where they will be rapidly transformed to other ...

Autocrine and paracrine unpaired signalling regulate intestinal stem cell maintenance and division

Bruno Lemaitre, Sveta Chakrabarti, Dani Osman

The Janus Kinase (JAK) Signal Transducer and Activator of Transcription (STAT) pathway is involved in the regulation of Intestinal Stem Cell (ISC) activity to ensure a continuous renewal of the adult Drosophila midgut. Three ligands, Unpaired1, 2 and 3 are ...

Diabetes imaging — quantitative assessment of islets of Langerhans distribution in murine pancreas using extended-focus optical coherence microscopy

Dimitri Nestor Alice Van De Ville, Theo Lasser, Anthony Christopher Davison, Anne Grapin-Botton, Martin Villiger, Arno Pino Bouwens, Corinne Berclaz, Erica Martin-Williams, Joan Goulley

Diabetes is characterized by hyperglycemia that can result from the loss of pancreatic insulin secreting β-cells in the islets of Langerhans. We analyzed ex vivo the entire gastric and duodenal lobes of a murine pancreas using extended-focus Optical Cohere ...

Intestinal ferritin H is required for an accurate control of iron absorption

Lukas Kühn

To maintain appropriate body iron levels, iron absorption by the proximal duodenum is thought to be controlled by hepcidin, a polypeptide secreted by hepatocytes in response to high serum iron. Hepcidin limits basolateral iron efflux from the duodenal epit ...

Dendritic cell chemotaxis in 3D : new tools and insights

Dendritic cells (DCs) are crucial for the onset of adaptive immunity. Their outstanding migratory capacities in combination with their antigen presenting properties make them perfectly suited to pick up antigens in the periphery and transport them to the l ...

The Intestinal Nuclear Receptor Signature With Epithelial Localization Patterns and Expression Modulation in Tumors

Johan Auwerx, Kristina Schoonjans

BACKGROUND & AIMS: The WNT-adenomatous polyposis coli system controls cell fate in the intestinal epithelium, where compartment-specific genes tightly regulate proliferation, migration, and differentiation. Nuclear receptors are transcription factors funct ...

Pancreas-specific deletion of beta-catenin reveals Wnt-dependent and Wnt-independent functions during development

Jörg Hülsken, Anne Grapin-Botton

Mutations and deregulation of adenomatous polyposis coli (APC) and beta-catenin are implicated in specific cancers of the pancreas, but the role of Wnt pathway in normal pancreas development and homeostasis is unknown [1-4]. This article reports a comprehe ...

Ductal cells of the pancreas

Anne Grapin-Botton

Ductal cells of the pancreas form the epithelial lining of the branched tubes that deliver enzymes produced by pancreatic acinar cells into the duodenum. In addition, these cells secrete bicarbonate that neutralizes stomach acidity. During development, epi ...

Orion MinAngle: A flexure-based, double-tilting parallel kinematics for ultra-high precision applications requiring high angles of rotation

Reymond Clavel

If you need to design ultra-high precision devices for mechanisms with multiple axes there are not a lot of ways leading around flexure-based joints. Using this type of articulations totally eliminates backlash and friction and is, by this, providing an ac ...
