Upon activation at inflammatory sites, neutrophils release extracellular traps (NETs), being beneficial in infectious diseases, but rather detrimental during non-infectious diseases. To investigate this in detail, we will use intravital and ex vivo microscopy, whole-body imaging, and light sheet microscopy to analyze NET formation in the kidney during sterile inflammation, and in the lung during bacterial infection (1, 2). To further identify the implication of different signalling molecules, we will use knock-out or platelet-depleted mice to discriminate their contribution to NET formation (3, 4). Infecting mice with different S. aureus patient isolates will allow the analysis of NET degradation as evasion strategy (5). Using newly developed carbohydrate labelling and trackable disease markers will reveal the pathogeny of these bacterial strains.
