Figure Lengend Snippet: MPs released by LPS-treated THP-1 cells stimulate intracellular signaling in HUVECs. A total of 100 μg/mL of MPs from LPS-treated (A) or untreated (B) THP-1 cells was incubated in serum-free conditions with HUVECs. Phosphorylation of ERK1/2 and degradation of IκB-α were observed by Western blot at the indicated times. (C) Indicated amounts of MPs from LPS-treated THP-1 cells or 10 ng/mL of TNF-α were incubated in serum-free conditions with HUVECs for the indicated time. Phosphorylation of p65 was detected by Western blot. (D) Subcellular localization of p65 was examined in HUVECs after 1 or 2 hours of stimulation with MPs from untreated or LPS-treated THP-1 cells or 10 ng/mL of TNF-α. HDAC2 served as the nuclear loading control, and GAPDH served as a cytoplasmic loading control. Results are representative of 2 independent experiments.

Article Title: Sec22b regulates inflammatory responses by controlling the nuclear translocation of NF-κB

doi: 10.1101/2020.09.20.305383

Figure Lengend Snippet: (A) BMDC were incubated with LPS, PGN and zymosan and NO release was assessed by measuring NO 2 - over a period of 2-24 h. Data are presented as mean concentration ± SEM of three independent experiments done in triplicate wells. ***, p < 0.001. (B) The intracellular expression of iNOS (green) in non-stimulated (NS) or LPS-stimulated BMDC was visualized via confocal immunofluorescence microscopy. DNA is in blue; bar, 5 μm. (C) BMDC were stimulated with LPS for 24 h and the colocalization (white pixels, rightmost panels) of iNOS (green) with ER/ERGIC-associated proteins Sec22b, Stx5 (red); ERGIC maker ERGIC53 (red); and Golgi marker P115 (red) was assessed by immunofluorescence. DNA is in blue; bar, 5 μm. Images are representative of three independent experiments. (D) iNOS colocalization was quantified using the Pearson method (see also Figure S1). Data are presented as mean Pearson R coefficient ± SEM of three independent experiments (≥10 cells per experiment); each point represents the coefficient of a single cell.

doi: 10.1101/2020.09.20.305383

Figure Lengend Snippet: (A) BMDC were fed with opsonised zymosan and recruitment of iNOS (green), Sec22b (red) and Stx5 (red) was visualized via immunofluorescence 24 h post-internalization. Recruitment of LAMP-1 (red) was used as reference. Cytoplasmic and phagosomal (3X-enlarged insets) colocalization can be observed in the rightmost panels (white pixels). DNA is in blue; bar, 5 μm. Images are representative of three independent experiments. (B) Phagosomal recruitment quantification of the aforementioned proteins at 1 h and 24 h post-phagocytosis. Data are presented as mean % positive phagosomes ± SEM of three independent experiments done in triplicate coverslips; each point represents % recruitment in 100 phagosomes per coverslip. *, p < 0.05; ***, p < 0.001; ns, not significant.

Article Title: Sec22b regulates inflammatory responses by controlling the nuclear translocation of NF-κB

doi: 10.1101/2020.09.20.305383

Figure Lengend Snippet: To evaluate whether Sec22b modulates inflammatory effector secretion, LPS was used to stimulate JAWS-II cells transduced with an shRNA targeting Sec22b (shSec22b) or a scrambled sequence (shScr). Over a period of 24 h, the release of NO (A) TNF (B) and IL-6 (C) was quantified in cell culture supernatants. Data are presented as mean concentration ± SEM of three independent experiments done in triplicate wells. (D) NO secretion in control or LPS-treated RAW264.7 cells transfected with siRNA to a scrambled sequence, Sec22b or Stx5. Data are presented as mean concentration ± SEM of at least two independent experiments done in triplicate wells; each point represents the concentration of a well. (E) iNOS protein levels in non-stimulated (NS) or LpS-stimulated Sec22b-KD JAWS-II cells preincubated with DMSO or brefeldin A (BrefA) were assayed via Western blot. iNOS densitometries were normalized with those of the β-actin loading control, and expressed relative to NS-DMSO-treated cells. Images are representative of two experiments. (F) Inos, Tnf and Il6 mRNA levels in LPS-stimulated Sec22b-KD JAWS-II cells were assayed via RT-qPCR. Data are presented as mean relative expression ± SEM of two independent experiments done in duplicate wells; points represent relative expression in each well. *, p < 0.05; **, p < 0.01; ***, p < 0.001; ns, not significant.

doi: 10.15252/embj.201696273

Figure Lengend Snippet: Micrographs showing the cellular distribution of IRF3 (green) in WT and Ifih1 −/− MEFs detected with an anti‐IRF3 antibody 4 h after infection with RV. Arrows indicate the more intense cytosolic, perinuclear enrichment of IRF3 in the WT and Ifih1 −/− cells before infection. This fluorescence pattern changes to a relatively more intense nuclear (blue) staining of IRF3 in RV‐infected WT cells but not infected Ifih1 −/− cells. The nucleus is visualized with the Hoechst DNA stain.
