Blocking IL-1 reduced neutrophil influx in crystal-induced peritonitis and air pouch models. (A) IL-1R1 KOs showed fewer CPPD-induced peritoneal neutrophils (PBS: n=4 WT; n=3 IL-1R1 KO / CPPD: n=8 per genotype). (B) mIL-1 Trap (35 mg/kg) reduced CPPD crystal-induced peritoneal neutrophils (PBS: n=4 Vehicle / CPPD: n=6 per group). + p< 0.01; # p < 0.001 compared to controls. Data expressed as means + SEM.
