Furthermore, Fortunellin repressed the activity of the Toll‐like receptor 4 (TLR4)/nuclear factor kappa‐B (NF‐κB)/NLR Family Pyrin Domain Containing 3 (NLRP3) pathway in the LPS‐stimulated ALI model and LPS‐induced RAW264.7 cells. This evidence concerns the gene NFKB1 and acute respiratory distress syndrome.
