Casp1−/− were kindly provided by Dr. Thirumala-Devi Kanneganti (St. Jude Children's Research Hospital). Cre-ERTM (B6.Cg-Tg(CAG-cre/Esr1*)5Amc/J) mice and lysozyme M-Cre mice were purchased from The Jackson Laboratory (Sacramento, CA). Nlrp3fl(D301N)/+ mice were kindly provided by Dr. Hal Hoffman (University of California, San Diego), and have been previously described (52 (link), 54 (link), 85 (link)). Nlrp3CA/+ mice with constitutive activation of NLRP3 in myeloid cells driven by lysozyme M-Cre have been previously described (54 (link)). Cre-ERTM mice and Nlrp3fl(D301N)/+ mice were crossed to generate Nlrp3fl(D301N)/+;Cre-ERTM mice and Cre-ERTM mice. Injection of tamoxifen (i.p., 75 mg/kg body weight; Sigma-Aldrich) to Nlrp3fl(D301N)/+;Cre-ERTM mice and Cre-ERTM mice to yield inducible Nlrp3CA (iNlrp3CA) mice and control mice, respectively, has been previously described (85 (link)). Gsdmd−/− mice were kindly provided by Dr. V. M. Dixit (Genentech, South San Francisco, CA). Asc-citrine and Gsdme−/− mice were purchased from The Jackson Laboratory (Sacramento, CA). All mice were on the C57BL6J background and mouse genotyping was performed by PCR. All procedures were approved by the Institutional Animal Care and Use Committee of Washington University School of Medicine in St. Louis.
