Infection and Immunology

Ruland, Jürgen

Immunology. Inflammation. Cancer. Infection

Our Laboratory is interested in the molecular mechanisms of immune cell activation and in the pathogenesis of cancer. Using a wide variety of molecular, cellular and in vivo techniques we try to understand how the innate immune system detects microbial or endogenous danger and how subsequent intracellular signals drive inflammatory responses and host defense. In other projects, we are dissecting pathomechanisms of leukemia and lymphoma development and build novel models for these diseases. We hope that our work will contribute to the development of novel diagnostics and therapeutics for immune-mediated diseases and cancer.
