Molekulare Mechanismen der Thrombozyten-vermittelten Neutrophils Extracellular Trap Formation im Rahmen des akuten Nierenschadens.
Zusammenfassung der Projektergebnisse
In summary, we have identified a role for transcellular prostaglandin metabolism between neutrophils and platelets, mediated by metabolite shuttling via EVs and involving Cox1, which affects neutrophil recruitment and bacterial killing. These findings are of clinical importance, as the inhibition of cyclooxygenases is a common therapeutic approach for pain relief and anti-inflammatory therapy. In addition, the cyclooxygenase inhibitor acetylsalicylic acid (aspirin) is widely used for platelet inhibition in patients after cardiac bypass grafting. Thus, inhibitory effects on neutrophil recruitment may be of great importance in these patient collectives. Furthermore, the potential use of cyclooxygenase inhibitors could be of potential interest for the therapy of inflammatory disorders involving uncontrolled neutrophil recruitment and warrants further research in this field.
