GR actions over the repression of pro‐inflammatory genes requires a more accessible chromatin landscape in response to glucocorticoids in macrophages. (A) Volcano plot from RNA‐seq data in which each dot in red represents the differentially expressed genes (DEG) by Dex in LPS‐primed macrophages versus LPS‐treated with adjusted p < 0.05.

LYC antagonized DON-induced disruption of the interaction between TXNIP and NLRP3 by binding to TXNIP, inhibited NLRP3 activation and pyroptosis, and thus effectively delayed intestinal epithelium senescence. TXNIP can serve as a target for regulating mycotoxin-induced intestinal epithelium senescence and a fresh perspective into antagonizing pyroptosis.
