Division of Experimental Allergy and Immunodermatology

The Division of Experimental Allergy and Immunodermatology has several research laboratories covering more than 130 square meters on the Wechloy campus, which were completed in 2017. Our research focus is on autoimmune diseases such as bullous pemphigoid, allergies, cancer and inflammatory skin conditions such as atopic dermatitis, contact dermatitis and psoriasis.
We are particularly interested in the role of basophil and eosinophilic granulocytes and mast cells in these diseases, whose released inflammatory mediators play a crucial role in the severity of the symptoms of these diseases and also affect other immune cells that control these diseases. Our research is funded, inter alia, by the DFG. Methodologically, we cover the entire spectrum of cellular inflammatory research with target cell isolation, cell culture, Western blotting, PCR, immunohistochemistry, histamine release assays, ELISA, cytation imaging, and FACS.
Our teaching focuses on the entire spectrum of dermatology and allergy, the basics of immunology and biochemistry.

The focus of our research group is on autoimmune diseases, such as bullous pemphigoid, allergies, cancer and inflammatory skin diseases including atopic dermatitis, contact eczema and psoriasis. We are particularly interested in the role of basophils, eosinophils and mast cells in these diseases since the inflammatory mediators released from these cells play a crucial role in the severity of symptoms and also impact on other immune cells that govern these diseases. Our group has many years of experience in isolating and purifying human allergic effector cells in order to study their functional responses and shed light on the intracellular signaling mechanisms that control their reactivity. Our main goal is to understand the different roles these cells play in autoimmunity and allergies and in developing new therapeutic strategies.

Ongoing international research collaborations include the University of Groningen (NL), where we are researching the causes of skin blistering in bullous pemphigoid, Imperial College London (UK) and the University Clinic of Pulmonary and Allergic Diseases Golnik (SLO), where we are investigating the cellular causes for severe allergic reactions, and the University of Kent, where we are studying fundamental mechanisms responsible for autoimmune diseases and cancer.
