Abstract
BACKGROUND Inflammatory bowel disease (IBD) is a significant global health concern that can lead to depression in affected patients. Liquiritin apioside (LA) possesses anti-oxidative and anti-inflammatory properties. However, its anti-inflammatory mechanism in IBD has not been extensively studied. PURPOSE This study elucidates the pivotal role of LA in alleviating inflammation by regulating gut metabiota-derived metabolites and evaluating its regulative effects on promoting a balance of Th17/Treg cells in colitis mice. METHODS To evaluate the effect of LA on IBD,16S rRNA gene sequencing and UPLC-QTOF-MS analysis were used to identify the changes of intestinal bacteria and their metabolites. Cytokines levels were determined by ELISA and qPCR, while immune cell ratios were evaluated via flow cytometry. RESULTS Our findings revealed that LA treatment ameliorated general states of DSS-induced colitis mice and their accompanying depressive behaviors. Moreover, LA restricted the expression of pro-inflammatory cytokines and revised the imbalanced Treg/Th17 differentiation, while promoting SCFAs production in inflamed colon tissues. Fecal microbiota transplantation from LA-fed mice also corrected the imbalanced Treg/Th17 differentiation, indicating that LA-mediated restoration of the colonic Treg/Th17 balance mainly depends on the changes in gut metabolites. CONCLUSION These results provide scientific evidence explaining the apparent paradox of low bioavailability and high bioactivity in polyphenols, and suggesting that LA could be used as a potential dietary supplement for the prevention and improvement of IBD.
