ST2 gene deficiency alleviates acute gastric injury in mice by modulating inflammation and epithelial cell death

Figure 7 Recombinant interleukin-33 aggravates acute gastric tissue injury. A: Representative macroscopic images illustrating the extent of gastric mucosal damage; B and C: Quantitative evaluation of gastric injury: Gastric lesion score (%) (B) and ulcer area (mm²) (C), analyzed using ImageJ software; D: Microscopic assessment of tissue damage based on histological activity index, accompanied by representative hematoxylin and eosin staining images (magnified × 10 and × 40). Data are presented as mean ± SEM; n = 10 mice per group. ^aP < 0.05, ^bP < 0.01. WT: Wild type; rIL-33: Recombinant interleukin-33.
