Physiologic control of IDO competence in splenic dendritic cells.


Dendritic cells (DCs) competent to express the regulatory enzyme IDO in mice are a small but distinctive subset of DCs. Previously, we reported that a high-dose systemic CpG treatment to ligate TLR9 in vivo induced functional IDO exclusively in splenic CD19(+) DCs, which stimulated resting Foxp3-lineage regulatory T cells (Tregs) to rapidly acquire potent… (More)
