Figure Lengend Snippet: (A–C) Cell death over time in FasL (100 ng/mL)-stimulated primary murine neutrophils, peritoneal macrophages, and bone marrow-derived macrophages (BMDMs) isolated from indicated genotypes as measured by propidium iodide incorporation over time. See also . (D) Level of cleaved, active form of death caspases-8 and -7 over time in B6 and Trif −/− macrophages after FasL stimulation. (E) Cell death over time in BMDMs isolated from indicated genotypes as measured by propidium iodide incorporation over time. BMDMs were stimulated with low dose (5 IU) IFN-β overnight to mimic tonic interferon signaling. Data from cell death assays and western blots are representative of three or more independent experiments, and cell death data are presented as the means ± SD of triplicate wells (~5,000 cells per field of view [FOV]).

Article Snippet: Samples were incubated on plates overnight at 4°C before washing with 0.005% Tween 20 in PBS and adding polyclonal rabbit anti-mouse IFN-β antibody (R&D Systems, 32400–1; 1:2000 dilution in 10% FBS in PBS) overnight at 4°C.

Techniques: Derivative Assay, Isolation, Western Blot

Figure Lengend Snippet: (A) Levels of CXCL1 produced by macrophages of indicated genotype in response to FasL over time. Data points indicate individual mice as source of isolated macrophages. (B) IκBα and total and phosphorylated p65 over time in whole-cell lysates from B6, Cd14 −/− , and Trif −/− macrophages after FasL stimulation. (C, E, and F) Relative IFNB and ISG15 mRNA levels normalized to ACTB in response to FasL over time in indicated neutrophils and macrophages. (D) Total and phosphorylated forms of RIPK1 over time in whole-cell lysates from B6, Cd14 −/− , and Trif −/− macrophages after FasL stimulation. (G) Spleen levels of IFN-β 4 h post-mFasL injection of 0.3 μg/mL; each point represents an individual mouse. qPCR and ELISA data are presented as the means ± SD for duplicate wells from three or more independent experiments. Data from western blotting are representative of three or more independent experiments. ANOVA was used for comparison between groups: ns ( p > 0.05), * p < 0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001.

Figure Lengend Snippet: Fig. 6. ZBP1 promotes LPS-induced septic shock and poly(I:C)-induced inflammation. (A and B) Mouse body temperature (A) and survival (B) over time in B6, Trif/, and Zbp1/ mice after IP injection with 25 mg/kg LPS. (C–E) TNF, IFNβ, and IL-1β protein levels in the (C) serum, (D) spleen, and (E) heart of B6, Trif/, and Zbp1/ mice injected IP with 25 mg/kg LPS or i.v. with 15 mg/kg poly (I:C) 4 h after injection. (F) Relative LDH levels in the serum of B6, Trif/, and Zbp1/ mice injected IP with 25 mg/kg LPS or i.v. with 15 mg/kg poly (I:C) 4 h after injection. For ELISA and LDH assays, data points indicate individual mice tested (B6 PBS, n = 10; Trif/ PBS, n = 10; Zbp1/ PBS, n = 10; B6 LPS, n = 10; Trif/ LPS, n = 10; Zbp1/ LPS, n = 10; B6 poly(I:C), n = 5; Trif/
