ST2 deficiency impairs and interleukin-33 (IL-33) injection exacerbates dextran sulphate sodium (DSS) colitis. Groups of wild-type (WT) and ST2−/− mice were either fed or not fed with DSS and injected with IL-33 (1 μg/mouse/day) or PBS. (a) Diarrhoea score and (b) colon length (on day 20) in the mice were determined as described in the Materials and methods. (c) The colon sections were stained with haematoxylin & eosin and scored. Data are representative of two experiments, n = 5 mice per group, *P < 0·05, **P < 0·01 compared with PBS controls.
