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

Accumulating evidence suggests key roles of the coagulation system and innate immune responses during sepsis and ALI. The release of a plethora of inflammatory mediators (e.g. IL-27, C5a) is observed and accompanied by complex interactions of intracellular signaling cascades and down-stream effects on coagulation. The focus of our research projects is on the molecular interactions of blood coagulation and the innate immune responses. In detail, the roles of plasmatic and cellular components of coagulation are investigated. We study the immune-modulatory functions of platelets and role of coagulation factors in macrophages 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 ALI.

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