One of the key cytokines involved in pulmonary inflammation and fibrosis is transforming growth factor‐β1 (TGF‐β1) (Munger et al., 1999; Ong et al., 2021), whose expression and activity have been shown to be increased in pulmonary fibrosis in advanced aging (Ramirez et al., 2007; Sueblinvong et al., 2012). The gene discussed is TGFB1; the disease is pulmonary fibrosis.
