Fig. 4.
Cell surface expression of MPO and PR3 on PMNs primed with TNF-α (2 ng/mL) for 10 minutes (FACScan analysis).
The bold line represents expression after priming; the thin line represents before priming. Increased PR3 but not MPO cell surface expression was detected as shown by 2 typical shifts observed after priming. Similar results were obtained for 4 individual experiments.
