Sepsis is a heterogeneous syndrome defined as a life-threatening organ dysfunction caused by a dysregulated host response to infection. Despite major improvements in patient care, the incidence of sepsis is rising, demonstrating the need to identify biomarkers and targets that can be used to develop personalized sepsis medicine.
Combining preclinical mouse models of sepsis with clinical studies, we contribute to the understanding of host defense mechanisms and the pathophysiology of sepsis and the identification of sepsis biomarkers (such as the myeloid-derived suppressors cells, MDSCs). In a proof-of-concept study, we have demonstrated the feasibility to target innate immune receptors (i.e. Toll-like receptor 4) to combat sepsis. In Switzerland, we launched the Swiss Sepsis National Action Plan (SSNAP; see www.sgi-ssmi.ch/fr/news-detail/items/plan-daction-national-suisse-contre-sepsis.html) to raise awareness of sepsis among the general public and governing bodies. With European collaborators, we have set up the European Sepsis Academy (EU H2020 funding) to train a generation of young scientist and physicians in sepsis. As a culmination of years of research, we are running the H2020 ImmunoSep (https://www.immunosep.eu) and H2020 HDM-FUN (https://www.hdm-fun.eu) clinical trials applying personalized immunotherapy in sepsis and fungal infection.
