Absent in peripheral tissues during homeostasis, human plasmacytoid dendritic cells (pDCs) are described in inflamed skin or mucosa. Here, we report that, unlike blood pDCs, a subset of tonsil pDCs express functional CCR6 and CCR10, and their respective ligands CCL20 and CCL27are detected in inflamed epithelia contacting blood dendritic cell antigen 2(+) pDCs. Moreover, pDCs are recruited to imiquimod-treated skin tumors in WT but not CCR6-deficient mice, and competitive adoptive transfers reveal that CCR6-deficient pDCs are impaired in homing to inflamed skin tumors after intravenous transfer. On IL-3 culture, CCR6 and CCR10 expression is induced on human blood pDCs that become responsive to CCL20 and CCL27/CCL28, respectively. Interestingly, unlike myeloid DC, blood pDCs initially up-regulate CCR7 expression and CCL19 responsiveness on IL-3 ± CpG-B and then acquire functional CCR6 and CCR10. Finally, IL-3-differentiated CCR6(+) CCR10(+) pDCs secrete high levels of IFN-α in response to virus. Overall, we propose an unexpected pDCs migratory model that may best apply for mucosal-associated lymphoid tissues. After CCR7-mediated extravasation into lymphoid tissues draining inflamed epithelia, blood pDCs may be instructed to up-regulate CCR6 and/or CCR10 allowing their homing into inflamed epithelia (in mucosae or skin). At this site, pDCs can then produce IFN-α contributing to pathogen clearance and/or local inflammation.
