Another miRNAs, miR-155 seems to activate the IL-8-dependent inflammation in patients with CF; high levels of miR-155 in sterile CF cells decreased after exposure to the anti-inflammatory cytokine IL-10 or following inhibition of IL-1β signaling,[11] followed by decreasing levels of IL-8 production. This evidence concerns the gene CXCL8 and cystic fibrosis.
