In addition, resveratrol can scavenge free radicals and activate antioxidant enzymes, such as superoxide dismutase (SOD), glutathione peroxidase (GPx), and glutathione reductase (GSSG-R), to maintain the dynamic balance of intracellular glutathione, thereby improving pulmonary fibrosis [8]. This evidence concerns the gene SOD1 and pulmonary fibrosis.
