Respiratory burst of neutrophils on endothelial cells bearing ICs (black bars) or untreated (white bars) under static conditions (static) or rotating shear stress (nonstatic). The endothelial monolayers were preincubated for 2 hours with the indicated stimuli. Values are expressed as mean ± SEM of three experiments;P < .001 between experiments with untreated and IC-bearing HUVECs; *nonsignificant experiment. Particular experiments were performed using the same batch of neutrophils and endothelial cells.
