Mitochondrial ROS Launch the Pathogenic Mitochondrial-Lysosomal-ER Circuit that Leads to Mitochondrial Ca2+ Overload and Macrophage Necrosis (A) Time-lapse confocal images of an infected macrophage in a 1 dpi mitGCaMP3 larva at indicated time points after TNF administration with MitoTracker Red CM-H2Xros. Scale bar, 5 μm. (B) Percentage of Rhod-2-positive macrophages in 1 dpi control and TNF-high larvae treated with NAC, GSH, MitoTEMPO, or amifostine. Horizontal bars, means; ∗∗∗p < 0.001 (one-way ANOVA with Tukey’s post-test). (C) Quantification of mitochondrial ROS production in 1 dpi TNF-high or control larvae that are WT, WT treated with necrostatin-1, PGAM5 morphant, or RIPK3 mutant. Horizontal bars, means; ∗∗∗p < 0.001 (one-way ANOVA with Tukey’s post-test). (D) Percentage of Rhod-2-positive macrophages in 1 dpi control and TNF-high larvae control, that are WT, WT treated with necrostatin-1, PGAM5 morphant, or RIPK3 mutant. Horizontal bars, means; ∗∗∗p < 0.001 (one-way ANOVA with Tukey’s post-test). (E) Quantification of mitochondrial ROS production in 1 dpi TNF-high or control larvae that are WT, WT treated with desipramine, or cathepsin D morphant. Horizontal bars, means; ∗∗∗p < 0.001 (one-way ANOVA with Tukey’s post-test). (F) Quantification of mitochondrial ROS production in 1 dpi TNF-high or control larvae that are WT, WT treated with dantrolene, BID morphant, or BAX mutant. Horizontal bars, means; ∗p < 0.05; ∗∗p < 0.01 (one-way ANOVA with Tukey’s post-test). (G) Quantification of mitochondrial ROS production in 1 dpi TNF-high or control larvae that are WT, WT treated with alisporivir, or cyclophilin D morphant. Horizontal bars, means; ∗p < 0.05; ∗∗p < 0.01 (one-way ANOVA with Tukey’s post-test). (H) Percentage of Rhod-2-positive macrophages in 1 dpi TNF-high or control larvae that are WT, WT treated with alisporivir, or cyclophilin D morphant. Horizontal bars, means; ∗∗∗p < 0.001 (Fisher’s exact test). (I) Cording in 5 dpi TNF-high or control larvae that are WT, WT treated with alisporivir, or cyclophilin D morphant. ∗∗p < 0.01; ∗∗∗p < 0.001 (Fisher’s exact test). See also |
