Third, biomarkers of fibrogenesis, including N-terminal pro-peptide of type III collagen, C-terminal pro-peptide of type I collagen, TGF-β, and alveolar fibroblasts and fibrocytes are detected in the bronchoalveolar fluid as early as 24 h after the onset of ARDS and correlate with mortality, as reviewed in (Wang et al. 2019; Capelozzi et al. 2017). The gene discussed is TGFB1; the disease is acute respiratory distress syndrome.
