Correlation of neutrophil elastase (NE) exocytosis by airway neutrophils, and free extracellular NE activity with structural lung damage. (A) Correlation of the PRAGMA-%Dis with airway neutrophil CD63 levels (n = 33). (B) Correlation of the PRAGMA-%Dis score with free extracellular NE activity (interpolated to a concentration of recombinant NE standard expressed in ng/ml; n = 29). MFI = median fluorescence intensity; PRAGMA-%Dis = Perth-Rotterdam Annotated Grid Morphometric Analysis for Total Disease.
