In contrast to SLPI KO mice treated with the control solvent, BPTI-treated SLPI KO mice showed reduced airway inflammation, fewer total BAL cells, and lower ratios of eosinophilia and Th2 cytokines, including IL-5 and IL-13, in BAL fluid (Figures 6A-6D). This evidence concerns the gene SLPI and Increased total eosinophil count.
