Abstract | BACKGROUND: Regulatory T cells (Tregs) have become promising candidates for immunotherapy in allergic rhinitis (AR). The contributing role of tolerogenic dendritic cells ( tDCs) in the augmentation of Tregs in AR remains to be determined. METHODS: The properties of tDCs in expanding Tregs and their potential to ameliorate AR were evaluated in vitro and in vivo. RESULTS: Monocyte-derived tDCs stimulated with Dermatophagoides pteronyssinus allergen 1 favored the generation of activated Tregs (aTregs) and suppressed effector T-cell responses in a transforming growth factor-beta/ interleukin-10 (TGF-β/IL-10)-dependent manner in vitro. The adoptive transfer of tDCs inhibited allergic airway inflammation in the mouse model, whereas depletion of CD25+ cells or blocking TGF-β/IL-10 signaling eliminated the inhibitory effect, indicating that Tregs were involved in the anti-inflammatory activity of tDCs. CONCLUSION: Our data show that tDCs are a potential therapeutic target in AR.
