Cldn3KO mice are susceptible to colitis.
Cldn3KO mice and WT littermates were subjected to murine models of colitis to evaluate the role of colonic CLDN3 in IBD. (a) % change in body weight of Cldn3KO mice during acute DSS colitis; (b and c) Colon length and colon thickness in Cldn3KO mice versus WT littermates upon acute DSS treatment; (d) Disease activity index; (e and f) Representative H&E images and injury score in Cldn3KO mice subjected to acute DSS colitis; (g and h) Colon length and colon thickness in Cldn3KO mice subjected to chronic DSS colitis; (i and j) Representative H& E images and injury score in Cldn3KO (vs WT) mice subjected to chronic DSS colitis; (k) % change in body weight of Cldn3KO mice subjected to C. rodentium colitis; (l) Colon thickness in Cldn3KO mice versus WT littermates, and (m and n) Representative H&E images and collective injury score in Cldn3KO mice compared to WT littermates. *P < .05, **P < .01, and ***P < .001. Scale bar = 50 μm.
