The on-purpose-modulated dendritic cells (DCs) have shown charming effects on restoring immune regulatory functions in subjects with immune diseases.,This study aims to construct DCs carrying chimerical antigen (Ag) peptides (CAP-DCs) to induce interleukin (IL)-17+ inducible Tregs (iTregs) to alleviate food allergy (FA) in a murine model.,In this study, we constructed CAP-DCs. The CAP is a fusion protein, consisting of a segment of recombinant scFv of anti-DEC205 antibody and an ovalbumin (OVA) epitope (IC). A murine OVA-FA model was developed to test the effects of CAP-DCs on suppressing the allergic response in the intestine.,The CAP-DCs are characterized as that a complex of scFv-IC is presented on the surface of the cells, moderately express CD80 and CD86 as well as IL-6, IL-23, transforming growth factor (TGF)-β and CCR9. After being passively transferred with CAP-DCs or injection of scFv-IC, Ag-specific IL-17+ Foxp3+ iTregs were induced in the intestinal lamina propria of FA mice. The iTregs showed immune suppressive effects on Ag-specific Th2 response. FA mice were adoptively transferred with the CAP-DCs or scFv-IC injection, which resulted in a significant decrease in the number of Ag-specific Th2 cells and suppression of FA response in an Ag-specific manner.,CAP-DCs can ameliorate FA response by inducing Ag-specific IL-17+ Foxp3+ iTregs and suppressing Ag-specific Th2 response. To generate CAP-DCs has the translational potential in the treatment of FA.,© 2019 John Wiley & Sons Ltd.
