It is unknown how dendritic cells (DCs) become specialized as mucosal DCs and maintain intestinal homeostasis. We report that bone marrow cells express the retinoic acid (RA)-synthesizing enzyme ALDH1a2, and provide RA to DC precursors in the bone marrow microenvironment. RA induced bone marrow-derived DCs (BMDCs) to express CCR9 and ALDH1a2, and conferred upon them mucosal DC functions. This was dependent on a narrow time window and stringent dose effect. RA promoted BMDC production of bioactive TGF-β by inhibiting SOCS3 expression and hence enhancing STAT3 activation. These RA effects were evident in vivo, in that vitamin A-deficient mucosal DCs had reduced mucosal function, namely failure to induce Foxp3+ regulatory T cells. Lastly, MyD88 signaling enhanced RA-educated DC ALDH1a2 expression, and was required for TGF-β production. These data indicate that RA plays a critical role in the generation of mucosal DCs from bone marrow as well as in their functional activity.
