Fig. 6From: Pirfenidone inhibits myofibroblast differentiation and lung fibrosis development during insufficient mitophagyHypothetical model of the anti-fibrotic mechanisms of PFD. PFD has previously reported anti-fibrotic mechanisms, including anti-inflammation, anti-pro-fibrotic cytokines, and anti-oxidative properties. Now PARK2-mediated autophay/mitophgy can be included in the anti-fibrotic properties of PFD. Although detailed mechanism remains elusive, PFD attenuates lung fibrosis seen during insufficient mitophagy through regulation of PDGFR-PI3K-Akt signaling by inhibiting mitochondrial ROS productionBack to article page
