Type 2 immune responses and effector cells in host defense and disease

Type 2 immunity is key for tissue recovery after injury as well as host defense against parasites and toxins. At the same, time mis-directed type 2 immune responses can lead to allergies. The propensity to develop type 2 immune responses can be influenced by the history of prior immunological exposures, such as microbial infections.

We aim to better understand the mechanisms of adaptive type 2 immune responses and how they are influenced by prior interactions with commensal and pathogenic microbes. In addition, we are fascinated by the enigmatic biology and functions of innate type 2-related immune effector cells like mast cells, eosinophils and basophils in host defense, physiology and disease.

Ultimately, we want to exploit the gained knowledge for the development of novel treatments and therapeutic strategies for infectious and allergic diseases.
