There was a positive correlation between NE production and the intensity of phagocytosis of unstimulated CF neutrophils (r = 0.584, p < 0.05), as well as CF neutrophils stimulated with PMA (r = 0.828, p < 0.05), fMLP/LPS (r = 0.604, p < 0.05), OpZym (r = 0.793, p < 0.05), P. aeruginosa (r = 0.590, p < 0.05), and CaI (r = 0.734, p < 0.05) (Figure 5B). This evidence concerns the gene FPR1 and cystic fibrosis.
