From: Loss of IL-33 enhances elastase-induced and cigarette smoke extract-induced emphysema in mice
Assessment of cigarette smoke extract (CSE)-induced emphysema. a Experimental protocol. b Representative images of H&E-stained lung tissue (magnification: × 200). c Lm values. WT PBS: WT mice treated with PBS. IL-33−/− PBS: IL-33−/− mice treated with PBS. WT CSE: WT mice treated with CSE. IL-33−/− CSE: IL-33−/− mice treated with CSE. Results for each group are shown as mean ± SEM (n = 7–8 in each group). *P < 0.05 compared to WT PBS; **P < 0.05 compared to IL-33−/− PBS; #P < 0.05 compared to WT CSE
