Hollow cerium nanoparticles synthesized by one-step method for multienzyme activity to reduce colitis in mice

Figure 5 Hollow cerium inhibits inflammatory factors. A-C: The expression levels of pro-inflammatory factors tumor necrosis factor-α (A), interleukin-6 (B), and monocyte chemoattractantprotein-1 (C) in serum were detected by enzyme-linked immunosorbent assay; D: Myeloperoxidase activity in serum. ^aP < 0.01; ^bP < 0.001. DSS: Dextran sulfate sodium; H-CeO₂: Hollow cerium; SASP: Sulfasalazine; TNF: Tumor necrosis factor; IL: Interleukin; MCP: Monocyte chemoattractantprotein; MPO: Myeloperoxidase.
