The THP-1 cells and primary macrophages were treated with NS RNA or FIP2 siRNA before primed with 100 ng/mL LPS for 2 h and treated with 5 mM nigericin as indicated (C-F). ASC-specks were identified using the IMARIS 8.2 imaging software on 3-D confocal imaging data.

Techniques:

(A) WT and Peli1-KO BMDMs were treated with 1 µg/mL LPS for 3.5 h with (+) or without (−) further stimulation with ATP, nigericin, alum, poly(dA:dT), flagellin, and MDP. The conditioned media were collected and subjected to ELISA to determine the level of IL-1β and IL-18 (WT, n = 3; KO, n = 3). (B) WT and Peli1-KO BMDMs were either NT or primed with 1 µg/mL LPS for 3.5 h followed by a further incubation without (NT) or with the indicated NLRP3 inducers. Cell lysates and precipitated conditioned media (Sup) were analyzed by immunoblotting to detect the indicated proteins. (C) WT and Peli1-KO BMDMs were NT (−) or primed with 500 ng/mL Pam3CSK4 for 3.5 h with (+) or without (−) further stimulation with ATP and nigericin for 30 min. Conditioned media were collected for ELISA to determine the level of IL-1β and TNF-α (for IL-1β: WT, n = 3; KO, n = 3; for TNF-α: WT, n = 4; KO, n = 4). (D) WT and Peli1 KO BMDMs were primed with (+) 500 ng/mL Pam3CSK4 for 3.5 h and then further incubated without (NT) or with the indicated inflammasome inducers. Cell lysates and precipitated conditioned media (Sup) were analyzed by immunoblotting to detect the indicated proteins. (E and F) 8-week-old Peli1-KO or WT control mice were i.p. injected with MCC950 for 2 h before LPS challenge. The serum was collected 2 h later for IL-1β ELISA, and mouse viability was monitored daily (WT, n = 9; KO, n = 10). Data are representative of three independent experiments, and bar graphs are presented as mean ± SEM of biological replicates. p values were determined by a two-tailed unpaired Student’s t test (A, C and F) or Kaplan-Meier method with a log-rank test (E): *p < 0.05; **p < 0.01; ***p < 0.001.
