Antibodies used were: Flag (Sigma-Aldrich), HA (Roche), LC3 (Sigma-Aldrich), AMPK, ULK1 p-Ser 317, and p-Ser 555 (Cell Signaling Technology), NLRP1 (Cell Signaling Technology), NLRP3 (Adipogen), Caspase-1, and ULK1 (Santa Cruz Biotechnology, Inc.), and GFP, IRF3, Myc, and Actin (Abcam). To determine autophagic activity by immunoblotting, cells were cultured in the presence of bafilomycin A1, and lysates were subjected to immunoblotting as described previously (Mizushima et al., 2010 (link)). The reagents used were Ultrapure LPS (InvivoGen), IFN-γ (PeproTech), Cytotoxic LDH assay (Promega), and TO-PRO-3 Iodide (Life Technologies). Immunoblotting and immunostaining were conducted as previously described (Kyei et al., 2009 (link)). FAM-YVAD-FMK stainings (FLICA; ImmunoChemistry Technologies) were performed according to the manufacturer’s instructions.
