IL1B and acute respiratory distress syndrome: In addition, during the progression of CLP-induced ALI or ARDS, the infiltration of neutrophils into the lung tissue causes the release of neutrophil extracellular traps and IL-1β, which upregulate the level of NLRP3, NLRP3 inflammasome assembly, and caspase-1 activation in AMs, leading to the AMs pyroptosis and sustain lung injury [95].
