Sepsis and lung injury (ALI, ARDS) are life-threatening diseases and frequently require treatment in critical care medicine. The annual incidence of sepsis and ARDS is estimated more than 150,000 cases in Germany. Immunocompromised patients are under increased risk for the development of infections such as pneumonia, which can progress to ARDS and/or sepsis. Additional complications can arise from severe disturbances in the blood clotting system (e.g. disseminated intravascular coagulopathy) during sepsis and ARDS.

Accumulating evidence suggests key roles of the coagulation system and innate immune responses during sepsis and lung injury. The release of a plethora of inflammatory mediators (e.g. IL-27, C5a) is accompanied by complex interactions of intracellular signaling cascades mediating down-stream effects on coagulation. The focus of our research projects is on the molecular interactions of blood coagulation and the innate immune responses. We study the immune-modulatory functions of platelets and role of coagulation factors in macrophages, neutrophils and type II alveolar epithelial cells. Additional projects are related to novel pathogen-associates molecular patterns (e.g. polyphosphates), signal transduction pathways (e.g. MAVS, MDA5, RIG-I) and neutrophil extracellular traps in the context of coagulopathies during sepsis and ARDS.

Our studies will contribute to a better understanding of the molecular pathogenesis of sepsis and lung injury, thereby helping to identify new avenues for therapeutic interventions.
