    Tmem45b is essential for the calcium regulation of ER. (A) Representative immunostaining images show the colocalization between Tmem45b (green) and <t>TGN38</t> (red) in the DRG tissue sections. Scale bar, 20 μm. (B) The volcano plot illustrates the significant differences between WT and CKO mice (WT vs. cKO, n = 3 vs. 4), assessed based on the fold change (cKO/WT) and adjusted p-value (padj). Blue dots represent genes that are significantly downregulated (fold change <0.67; padj <0.1), red dots indicate significantly upregulated genes (fold change >1.5; padj <0.1). Genes represented by black dots show no significant differences between the groups. (C) qPCR analysis. (WT vs. cKO, n = 4 vs. 4). Columns represent the mean expression level of Atp2a1 mRNA normalized to Gapdh . (D) Western blot analysis. Experiments are repeated three times. (E) Schematic of calcium imaging in dissociated DRG neurons response to thapsigargin. (F) Representative calcium imaging response to thapsigargin (100 μM). (G) Statistical results. (WT vs. cKO, n = 90 vs. 72). (H) Schematic of calcium imaging in dissociated DRG neurons in response to caffeine (10 mM). (I) The heatmap shows the calcium activity of DRG neurons in response to two rounds of caffeine stimulations. Neuron numbers are shown on the left of the image. (J) Statistical results. (K) Schematic of calcium imaging in dissociated DRG neurons response to Trypsin (500 nM). (L, M) Representative calcium response to Trypsin. (N) Statistical results. (WT vs. cKO, n = 227 vs. 217). Two-tailed unpaired Student’s t test. DRG was obtained from at least three mice. Data are expressed as the Mean ± S.E.M. * P < 0.05, ** P < 0.01, *** P < 0.001.

(A) Representative immunostaining images show the colocalization between Tmem45b (green) and TGN38 (red) in the DRG tissue sections. Scale bar, 20 μm. (B) The volcano plot illustrates the significant differences between WT and CKO mice (WT vs. cKO, n = 3 vs. 4), assessed based on the fold change (cKO/WT) and adjusted p-value (padj). Blue dots represent genes that are significantly downregulated (fold change <0.67; padj <0.1), red dots indicate significantly upregulated genes (fold change >1.5; padj <0.1). Genes represented by black dots show no significant differences between the groups. (C) qPCR analysis. (WT vs. cKO, n = 4 vs. 4). Columns represent the mean expression level of Atp2a1 mRNA normalized to Gapdh . (D) Western blot analysis. Experiments are repeated three times. (E) Schematic of calcium imaging in dissociated DRG neurons response to thapsigargin. (F) Representative calcium imaging response to thapsigargin (100 μM). (G) Statistical results. (WT vs. cKO, n = 90 vs. 72). (H) Schematic of calcium imaging in dissociated DRG neurons in response to caffeine (10 mM). (I) The heatmap shows the calcium activity of DRG neurons in response to two rounds of caffeine stimulations. Neuron numbers are shown on the left of the image. (J) Statistical results. (K) Schematic of calcium imaging in dissociated DRG neurons response to Trypsin (500 nM). (L, M) Representative calcium response to Trypsin. (N) Statistical results. (WT vs. cKO, n = 227 vs. 217). Two-tailed unpaired Student’s t test. DRG was obtained from at least three mice. Data are expressed as the Mean ± S.E.M. * P < 0.05, ** P < 0.01, *** P < 0.001.

    a Conserved basic segments within the linker and FISNA region of NLRP3 homologs. b Immunoblot of non-localized and organelle-tethered NLRP3-YFP with respective NLRP3 mutants K127A/K128A/K129A/K130A (4xA). c – h Confocal images of NLRP3-KO iBMDMs stably transduced with organelle-tethered NLRP3-YFP (yellow) variants 12 h post priming with or without nigericin stimulation (Nig), stained for nuclei (Hoechst 33342, cyan) and plasma membrane (Cholera Toxin Subunit B, CTB, magenta). Scale bar, 10 µm. Following priming, 10 µM nigericin, 0.2 mg/ml SiO 2 or 20 ug/ml imiquimod (Imq) were added to cells, respectively, as indicated in the respective graph columns with legends above. Measurements of IL-1β were normalized to each respective non-mutated, organelle-enriched NLRP3-YFP: WT ( c ), Cb5 ( d ), TGN38 ( e ), HRas ( f ), Rheb ( g ) or Omp25 ( h ) treated with canonical stimuli: nigericin, SiO 2 or imiquimod, respectively. EV, empty vector. Data represents the mean ± SEM of three independent experiments, except for TGN38, treated with SiO 2 in ( e ), which is the mean ± SEM of two independent experiments. The average value calculated from technical replicates within an individual experiment is presented as a single data point. P values were calculated using two-tailed unpaired t -test with Welch’s correction ( c – h ). Western blots ( b ) and microscopic images ( c – h ) are representative of three independent experiments.
