Staining of human airway: SCGB1A1 in red

Aim of this research team is to understand how environmental triggers can cause diseases such as allergic rhinitis, asthma or infections such as COVID-19.

The airway epithelial cells constitute the barrier to our environment and are tohether with immune cells scattered into this layer the first cell exposed to environmental components such as allergens, viruses or pollutant particles. Focus of the AiwayImmunology group lies on epithelial cell biology and its cross talk with the immune system (T cells, innate lymphocytes and makrophages). There are crucial changes in the airway epithelium that can prime both epithelial differentiation and immune system that can ultimately lead to asthma pathogenesis. We investigate the role of airway epithelium in allergic inflammation under the influence of Th1/Th2 mediators. Aim of the study is the understand the crosstalk between epithelial cells and immune cells in order to identify specific biomarkers for allergic inflammation. Allergen specific immunotherapy is another focus that is investigated and therapeutic efficacy is investigated at the epitheial barrier as well. The group is also interested in food allergy and the intestinal barrier. Airway projects are supported by the DZL (German Lung Research Center), Biomarker studies are supported by the ZAUM-led EIT Health EU consortium "ADAPT". Food allergies are investigated in the ZAUM-led BMBF consirtium "ABROGATE".
