Figure 4B shows that the conditioned medium of CF incubated with IFN-β reduced the migration of neutrophils induced by the conditioned medium of CF treated only with LPS (45% vs. 70%), while the conditioned medium of CF incubated with ruxolitinib inhibited the antimigratory capacity observed with IFN-β (60% vs. 45%). This evidence concerns the gene IFNB1 and cystic fibrosis.
