Fecal microbiota transplantation from patients with IBD/D or IBD/D+ and healthy volunteers (HVs) caused anxiety/depression in the transplanted mice. Effects on the occurrence of anxiety/depression in the EPM (a), LDT (b), MB tasks (c), TST (d), and FST (e). Effects on the IL-1β expression (f), BDNF+/NeuN+, NF-κB+/Iba1+, LPS+/Iba1+ and IL-1R+ cell populations in the hippocampus (g). Effects on the corticosterone (h), IL-1β (i), IL-6 (j), and LPS levels (k). Each HV-F (n = 6), IBD/D-F (n = 8), or IBD/D+-F (n = 7) was orally transplanted in three mice once a day for 5 days. Control mice were treated with vehicle (saline) instead of fecal suspension. Data values were indicated as mean ± SD (NC n = 6; HV-F n = 6; IBD/D n = 8; IBD/D+ n = 7: each n value is the average obtained from 3 mice). Means with same letters are not significantly different (p < 0.05). All data were analyzed using ANOVA with Tukey’s multiple comparisons test.
