Kynurenine:tryptophan (Kyn:Tryp) ratio in unstimulated whole blood supernatants from healthy controls and IBS patients and following stimulation with: (A) TLR1/2 agonist Pam3Csk, (B) TLR2 agonist HKLM, and (C) TLR3 agonist Poly I:C. Data are expressed as mean ± SEM. Statistical differences between treatments and disease states were determined using two-way ANOVA with Bonferroni post hoc test. *p < 0.05, Healthy control stimulated vs. unstimulated; ***p < 0.001, healthy control stimulated vs. unstimulated; $ p < 0.05, IBS stimulated vs. unstimulated.
