Homing of GAD65 specific autoimmunity and development of insulitis requires expression of both DQ8 and human GAD65 in transgenic mice

MHC-class II genes determine susceptibility in human type-1 diabetes. In their context, presentation of target antigen(s) results in autoimmunity and b-cell destruction. An animal model, in which human b-cell autoantigen(s) are presented to effector cells ...

Conditional ablation of Notch signaling in pancreatic development

Freddy Radtke

The role of the Notch signaling members Notch1, Notch2 and Rbpj in exocrine pancreatic development is not well defined. We therefore analyzed conditional pancreas-specific Rbpj and combined Notch1/Notch2 knockout mice using Ptf1a(+/Cre(ex1)) mice crossed w ...

Temporal control of neurogenin3 activity in pancreas progenitors reveals competence windows for the generation of different endocrine cell types

Friedrich Beermann, Anne Grapin-Botton

All pancreatic endocrine cells, producing glucagon, insulin, somatostatin, or PP, differentiate from Pdx1+ progenitors that transiently express Neurogenin3. To understand whether the competence of pancreatic progenitors changes over time, we generated tran ...

Pancreas development and cancer - Wnt/beta-catenin at issue

Anne Grapin-Botton

beta-catenin and Adenomatous poliposis coli (APC) have been implicated in non-ductal pancreatic cancers. As for many other organs, several recent publications show that beta-catenin and more largely the Wnt pathway appear to function at the level of pancre ...

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 ...
