E: Images of in situ efferocytosis in aortic root lesions: MAC2 ( Green ), TUNEL ( Red ), and DAPI ( Blue ). Scale bar, 60 μm. White arrows , nuclei double positive for TUNEL and MAC2. White wedges , nuclei positive for TUNEL but negative for MAC2. F: Percentage of TUNEL positive nuclei also positive for MAC2. P = 0.011 (Ctrl Baseline vs. Jak2 VF Baseline), P = 0.021 ( Jak2 VF Baseline vs. LDL Lowering). MAC2 intensity differences reflect independent staining and imaging sessions across panels, n = 13–24. All quantifications shown as mean ± s.e.m. Two-way ANOVA with Tukey’s multiple comparisons test (D). Kruskal-Wallis test with Dunn’s multiple comparisons test (B and F). DAPI, 4′,6-diamidino-2-phenylindole; LDL, low-density lipoprotein; MerTK, mer proto-oncogene tyrosine kinase; MPN, myeloproliferative neoplasm; TREM2, triggering receptor expressed on myeloid cells 2.

Aggressive cholesterol lowering more strongly decreases macrophage pyroptosis and DNA damage in Jak2 VF MPN lesions. A: Images of aortic root lesions stained for MAC2 ( Green ), cleaved GasD ( Red ), and DAPI ( Blue ). Scale bar, 60 μm. B: Log 10 transformed cleaved GasD MFI in the necrotic core with the addition of constant 1, n = 14–20. P = 0.0064 for genotype effect and P = 0.021 for treatment effect by two-way ANOVA. C: Images of aortic root lesions stained for MAC2 ( Green ), Cleaved GasD ( Red ), and DAPI ( Blue ). Scale bar, 60 μm. White arrows , cleaved GasD + macrophages. D: Log 10 transformed cleaved GasD positive macrophages per section with the addition of constant 1, n = 13–20. P = 0.023 (Ctrl Baseline vs. Jak2 VF Baseline), P = 0.005 ( Jak2 VF Baseline vs. LDL Lowering). E: Representative immunoblot analysis of full-length and cleaved GasD in CD11b + splenocytes. F: Log 10 transformed densitometric quantification of the ratio of cleaved GasD to full-length GasD from E with the addition of constant 1. n = 7–8 biological replicates. P = 0.0003 (Ctrl Baseline vs. Jak2 VF Baseline), P = 0.0046 ( Jak2 VF Baseline vs. LDL Lowering). G: Images of aortic root lesions stained for MAC2 ( Green ), pγH2AX ( Red ), and DAPI ( Blue ). Scale bar, 60 μm. White arrows , pγH2AX positive cells. H: Log 10 transformed pγH2AX positive cells per section with the addition of constant 1, n = 14–20. P = 0.016 (Ctrl Baseline vs. LDL Lowering), P = 0.0016 (Ctrl Baseline vs. Jak2 VF Baseline), P < 0.0001 ( Jak2 VF Baseline vs. LDL Lowering). All quantifications shown as mean ± s.e.m. Two-way ANOVA with Tukey’s multiple comparisons test (B, D, F, and H). DAPI, 4′,6-diamidino-2-phenylindole; GasD, gasdermin D; LDL, low-density lipoprotein; MFI, mean fluorescence intensity; MPN, myeloproliferative neoplasm; pγH2AX, phosphorylated histone H2A.X.
