TGFB1 and pulmonary fibrosis: Deficient autophagy in idiopathic pulmonary fibrosis inhibits fibroblast apoptosis (Romero et al., 2016; Wei, Sinha, y Levine, 2008) and promotes ECM deposition (Ricci et al., 2013; X. Zhang Xiaohuan et al., 2021), EMT/EndoEMT (Singh et al., 2015; Hill et al., 2019), myofibroblast transformation (Bernard et al., 2014; Im, Hergert, and Nho, 2015), and TGFβ1 signalling pathways (Patel et al., 2012; Ghavami et al., 2018).
