Tuft cells are required to induce AMP expression changes in response to bacterial dysbiosis in the distal SI. (A) Ileal tuft cell frequency in control or PEG-treated (12 d) Pou2f3+/− mice as determined by flow cytometry (n = 9 to 17 mice per group). (B) Expression of representative AMP genes determined by qRT-PCR in the ileal epithelial fraction of control or PEG-treated Pou2f3+/− and Pou2f3−/− mice (n = 5 to 17 mice per group). Relative expression normalized to Gapdh. Center values = median; error bars = IQR. Significance was determined using the Mann–Whitney U test. ns = no significance, *P < 0.05, **P < 0.01, ***P < 0.001.
