In brief, actions of some of the assessed interleukins in the context of pulmonary fibrosis can be summarized as follows: IL1ꞵ (pro-fibrotic), IL4 (pro and anti-fibrotic), IL6 (pro and anti-fibrotic), IL8 (pro-fibrotic), IL10 (anti-fibrotic), IL12 (anti-fibrotic), and IL13 (pro-fibrotic) [38]. This evidence concerns the gene IL10 and pulmonary fibrosis.
