Moreover, HMGB1 may be involved in the pathogenesis of asthma by regulating downstream signaling pathways through corresponding receptors and mediates a number of signaling pathways in asthma, such as HMGB1/TLR4/NF‐κB, HMGB1/RAGE, HMGB1/TGF‐β, and so forth. This evidence concerns the gene HMGB1 and asthma.
