Figure Lengend Snippet: Phagosome membrane damage occurs in cryptococcal-containing phagosomes. ( A ) Representative image showing a cryptococcal-containing phagosome positive for Gal-3 association. Gal-3 is widely used as a reporter of phagosomal membrane damage. These images were taken at 100×, with blue showing the nuclei of the C20 cells, green showing intracellular KN99α, and yellow showing Gal-3. The scale bar is 10 μm. ( B ) Percentage of fungal-containing phagosomes positive for Gal-3 association 24 h after engulfment was analyzed by immunofluorescence as shown in panel A . Both C. neoformans (KN99α)- and S. cerevisiae (BY4741)-containing phagosomes were tested for membrane damage. mCherry-expressing fungi were either unopsonized (unop.) or opsonized (serum) and incubated with microglia at an MOI of 20:1 for 3 h. Wells were washed three times with DPBS to remove extracellular fungi, and microglia were incubated for an additional 24 h then assessed for membrane damage via Gal-3 staining. Values represent the mean ± SEM from three biological replicates. For all experiments, significance was determined using one-way ANOVA with multiple comparisons (Brown-Forsythe and Welch’s corrected), *, P < 0.05; **, P < 0.005; ***, P < 0.0005; ****, P < 0.0001.

Figure Lengend Snippet: Western blot analysis of inflammatory and structural protein expression. a Representative western blot showing Galectin-3/Mac2 (Gal-3) expression in aortic tissue at 2 weeks (2 W) and 4 weeks (4 W) post-intervention versus control. b Quantification of Gal-3 levels reveals significant upregulation at 2 W (46.55 ± 7.31%) and 4 W (87.22 ± 11.14%) compared to control (18.86 ± 10.37%; p < 0.001). c WB showing α-smooth-muscle-actin (α-SMA) expression in the same groups. d Quantification shows reduced α-SMA expression at 2 W (52.79 ± 14.99%) and 4 W (39.16 ± 17.52%) versus control (80.94 ± 14.26%; p = 0.005 and p < 0.001, respectively). Individual values: n = 4 for 2 W (dots); n = 4 for 4 W (squares); n = 4 for controls (triangles). Statistical significance: ** p < 0.01, *** p < 0.001. 2 W, Two weeks; 4 W, Four weeks; α-SMA, α-smooth-muscle-actin; Gal-3, Galectin-3

Figure Lengend Snippet: Immunofluorescence analysis of macrophage infiltration and vascular smooth muscle cell loss. a Representative images of aortic tissue stained for Galectin-3 (Gal-3, magenta), α-smooth-muscle-actin (α-SMA; magenta), and DAPI (blue), in control, 2 weeks (2 W), and 4 weeks (4 W) post-intervention samples. Scale bars: 500 µm. b Gal-3-positive area increased significantly at 2 W (15.12 ± 3.88%) and 4 W (16.65 ± 5.27%) versus control (0.66 ± 0.27%; p = 0.012, and p = 0.021, respectively). c α-SMA-positive area decreased at 2 W (3.09 ± 0.70%) and 4 W (2.04 ± 1.43%) versus control (35.18 ± 5.15%; p = 0.003 for both comparisons). Quantified with Keyence Hybrid Cell Count (autothreshold; Version 2.1.1, Keyence Corp.), values signify positive area fraction. Individual values: n = 4 for 2 W (dots); n = 4 for 4 W (squares); n = 4 for controls (triangles). Statistical significance: * p < 0.05, ** p < 0.01. 2 W, Two weeks; 4 W, Four weeks; α-SMA, α-smooth-muscle-actin; Gal-3, Galectin-3
