Genetic and/or pharmacological inhibition of the IL-33/ST2 axis reduced colonic inflammation in a chemical-induced model of acute colitis. (A) Disease activity index (DAI), (B) Histological Score, (C) IL-6 and (D) KC ELISA from colon homogenates and (E) Colon length of dextran sodium sulphate (DSS)-treated wild-type and St2−/− animals. Mean values of DAI±SEM out of four independent experiments are shown. (F) DAI (G) Histological Score, (H) IL-6 ELISA from colon homogenates of DSS-treated mice administered 50 µg neutralising anti-ST2 antibody (rat IgG1) or isotype control intraperitoneally on days 1, 3, 5 and 7. (I) Histological Score and (J) Colon length of DSS-treated wild-type and IL-33-deficient mice. Mean values of four animals per group±SEM out of two independent experiments.
