Scientific Focus
Major interest of our group is to translate clinical findings of patients with inflammatory bowel diseases to the bench and vice versa with the ultimate goal to contribute to the understanding of the disease pathways as well as to identify possible novel therapeutic targets. Two main directions build the current focus of our group.

First, the biological and clinical significance of „creeping fat“, a pathognomic finding in patients with Crohn’s disease is not understood. The mesenteric fat tissue, initially considered as energy storage, not only harbors numerous immune cells but more important strongly regulates the immune response.

Thus the fat tissue builds the source of adipokines, chemokines and cytokines and more important adipocytes and preadipocytes themseives can be considered as cells of the innate immune system. The current work dissects the immune response in the mesenteric fat tissue adjacent to the inflamed intestine.

Second, chronic inflammation drives tumorigenesis in man and in mice. Modification of the state of histone and non-histone acetylation can regulate tumorigenesis as well as inflammation. Knockout mice as well as in vitro knockdown strategies serve to define the role of single histone deacetylases in models models of intestinal inflammation.

The Department for Gastroenterology, Infektiology and Rheumatology at the University Charité hospital in Berlin offers an outstanding treatment of specific areas. The director of this department is Prof. Dr. Britta Siegmund.

The Department of Gastroenterology, Infektiology and Rheumatology at the University Hospital Charité Berlin, located at the Benjamin Franklin campus, it focuses on chronic inflammatory diseases of the gastrointestinal tract and joints. A nother major focus is the for treatment of infections of the bowel and gastrointestinal tumour diseases. Patients with infectious diseases (HIV, tuberculosis, hepatitis, meningitis, endocarditis, gastroenteritis and sexually transmitted diseases), tropical diseases (malaria, schistosomiasis and leishmaniasis) and immunocompromised patients (due to autoimmune diseases, oncological diseases and HIV) are offered treatment at the Department of Gastroenterology, Infektiology and Rheumatology.

The Department of Gastroenterology, Infektiology and Rheumatology at the University Hospital Charité Berlin treats a wide range of rheumatic diseases. In addition, patients with typical symptoms such as swelling of the joints, backache and complex rheumatological diseases receive high-quality medical care at the Department of Gastroenterology, Infektiology and Rheumatology.
