Research interest

The main subjects of our work are the mechanisms of intestinal inflammation with special emphasis on T cells and myeloid cells but also the epithelial barrier. Since the founding of the group, we have a special interest in the role of the adipose tissue in the pathogenesis of chronic intestinal inflammation and its impact on the mucosal immune system. Additionally, we are interested in the immune evasion of tumors regarding the regulatory function of myeloid cells as well as CD8+ T cell activation.

Both subjects are investigated regarding the metabolic changes in the local microenvironment and epigenetic regulation of the respective cells via histone deacetylases.
