Beschreibung: We study the role of cell adhesion molecules of the JAM family in epithelial cells, endothelial cells and tumor cells. We have recently identified a novel JAM family member called JAM-M. JAM-M is localized at the brush border of cultured epithelial cells and is expressed by a specific subset of intestinal epithelial cells, in which it might play a role in brush border dynamics after helminth infection. In this project, we will study the role of JAM-M in the small intestine and in small intestine-derived organoids derived from mice. In our projects, we apply primarily methods of molecular biology, protein biochemistry and fluorescence microscopy. This project will largely make use of immunohistochemistry and high resolution microscopy. You should be interested in molecular cell biology, open to new technologies, and highly motivated. A willingness to work with laboratory animals will be essential. We offer an exciting new project, intensive supervision, and a strong scientific environment. For additional information, feel free to contact us by telephone or e-mail, or visit our web site ("zmbe münster"). If you are interested, please send your application as a pdf document to the indicated address.
