Scientific interest:

We are interested in intestinal wound- and anastomotic healing in inflammatory bowel disease. Our special interest lies in application of nanoparticle-based local and systemic treatment for induction of wound healing during intestinal inflammation.

Read Outs

Current projects:

• Investigation of the use of Ac2-26 loaded nanoparticles for induction of anastomotic healing during inflammatory conditions in the gut
• Assesment of Annexin A1 treatment for prevention of intestional fibrosis following ileocecal resection in a murine model of Crohns disease
• Analysis of Annexin A1 expression in surgical specimen of patients with Crohn´s disease
