Immune modulation by a mucin-containing diet.

(A–E) Caecal SCFA levels (A), frequencies of Foxp3⁺RORγt⁺ cells and Foxp3⁺RORγt⁻ cells within CD4⁺ T cells (B and C), and frequencies of IgA⁺B220⁻ cells within CD45⁺ cells (D and E) in the colonic mucosa of mice fed a control diet or a diet containing 1·5% porcine stomach mucin for 3 weeks. Representative flow cytometry plots are shown in B and D. Data represent the mean ± standard deviation (n = 5/group). ^⁎p < 0·05, ^⁎⁎p < 0·01, and ^⁎⁎⁎p < 0·001 (two-tailed Student's t-test).
