Sepsis trains stressed granulocytes to boost nonspecific response and trigger a new wave of inflammation when facing secondary infection. Here, we present a protocol for a murine model of sepsis with secondary infection. We describe steps for cecal ligation and puncture operation and rechallenging with lipopolysaccharide or Pseudomonas aeruginosa during the recovery phase. We also detail steps to characterize the stressed granulocytes by assessing their functional phenotypes and effect on the mortality of rechallenged mice. For complete details on the use and execution of this protocol, please refer to Wang et al.1.
