Communication between cells and inflammation

More than 400,000 people in Germany are affected by the chronic inflammatory bowel diseases Morbus Crohn or ulcerative colitis. Patients often suffer from flare-ups, during which the immune system in the intestines is falsely activated and intestinal tissue damaged. In spite of advances in treating the diseases with medication, the chronic inflammation still cannot be kept sufficiently in check for a number of patients. In addition, little is known about what actually causes flare-ups.

Sebastian Zundler and his team of researchers presume that intestinal TRM cells have a role to play in the development of bowel diseases such as these, as well as possibly also in other chronic inflammatory diseases such as rheumatoid arthritis. ‘Previous research has already shown that TRM cells have a key role to play in triggering flare-ups by regulating the migration and differentiation of other immune cells,’ explains Zundler. ‘We then succeeded in showing that TRM cells communicate and control other immune cells using various messenger substances.’ Zundler now hopes to decode and understand this communication network in order to be able to use it for therapeutic purposes.
