In contrast to DFO, extracellular GSH did reduce a subset of pro-inflammatory factors by more than 10-fold, including the pro-inflammatory cytokines CCL20, CSF-1, and MCP-1 that in BALF from CF infants are correlated with oxidative stress and lung disease (Horati et al., 2020). This evidence concerns the gene CCL20 and cystic fibrosis.
