MyD88IEC-KO/TRIFIEC-KO mice are not more susceptible to dextran sodium sulfate (DSS)-induced acute colitis. (A) Body weight change, (B) rectal bleeding score, and (C) diarrhoea score of TRAF6FL (n=8), TRAF6IEC-KO (n=8), MyD88FL/TRIFFL (n=7) and MyD88IEC-KO/TRIFIEC-KO (n=6) mice administered 1% DSS for 7 days followed by 2 days of normal drinking water. For A–C, asterisks indicate statistically significant differences between TRAF6FL and TRAF6IEC-KO mice. (D) Colon length, (E) histological tissue damage and inflammation scoring and (F) representative H&E stained colon cross-sections of indicated mice at day 9 of the DSS colitis protocol. Bars, 100 μm. All data shown are representative of two independent experiments. All statistical analyses were performed with unpaired two-sided Student's t tests with unequal variance.
