The mice are intraperitoneally administered with CDDO-imidazolide before thein vivo sepsis-associated ARDS model is constructed via caecal ligation perforation and the Nrf2 inhibitor, ML385.In vitro studies reveal that the use of 3-MA to prohibit PINK1/Parkin-dependent mitophagy aggravates NLRP3-mediated pyroptosis and HMGB1 release in J774A.1 cells via LPS and ATP exposure. Here, NLRP3 is linked to acute respiratory distress syndrome.
