Ex vivo cultures of neutrophil granulocytes demonstrating CPa9-HNE biomarker level fold-change compared with inactive neutrophils, reflecting true neutrophil activity. CPa9-HNE biomarker levels after A] 4 h of cultivation with neutrophil agonists B] and 24 h of cultivation; MRP8/14 biomarker measurements after C] 4 h of cultivation with neutrophil agonists D] and 24 h of cultivation. Definition: negative control [only tissue], S. aureus [tissue + Staphylococcus aureus], inactive neutrophils [tissue + neutrophils], neutrophils + S. aureus [tissue + neutrophils + Staphylococcus aureus], neutrophils], neutrophils + PMA [tissue + neutrophils + phorbol myristate acetate], neutrophils + Cal iono [tissue + neutrophils + calcium ionophore]. Error bars represent the standard error of the mean [SEM].
