The TLR-stimulant content of some processed foods can greatly exceed that of the normal mouse ileal microbiota. (A–C) Soluble TLR2, TLR4, and TLR5-stimulants were quantified in processed foods (n = 14), mouse chow (n = 6), mouse ileal ingesta (n = 5), mouse feces (n = 10) and human feces (n = 6) using HEK-293-TLR transfectants. (D-F) Pro-inflammatory cytokine production by primary human monocytes (n = 3 donors) exposed to extracts of mouse ileal ingesta, minced meat or chocolate (n = 5 extracts of each type), diluted 1:10 (wt/vol) in culture medium. P-values vs. ileal contents, ANOVA with Tukey's test.
