Mice were treated daily with 1 mg/kg fingolimod in 100 µL sterile water or an equal volume of sterile water by gavage from weaning. Colonic tissue was collected from 12-week-old mice. Western blot analysis of colonic TLR2, TLR4, p-P65, NLRP3, p20, and IL-1β expression and gray value analysis by ImageJ. The data are the mean ± SEM (n = 4 experiments with two pooled mice in each experiment/group). *P < 0.05 versus Con, **P < 0.01 versus Con.
