The elimination of dietary antigens decreases IgA production in the SI. (A) IgA concentration in feces from GF (n = 9) and GF-AF mice (n = 10). (B) Representative flow cytometry plots of IgA vs. B220 on CD3− lymphocytes of SI-LP and LI-LP of GF and GF-AF mice (left), and the absolute numbers of B220−IgA+ IgA-producing plasma cells (right). Data are pooled from at least three independent experiments and are presented as mean ± SD. Welch's t-test was used for statistical analysis. *p < 0.05, ***p < 0.001.
