(C) Microscopy images of sliced draining lymph nodes in CD11c‑eYFP:Irf3‑/‑Irf7‑/‑ chimeras with 90:10 (left) and 5:95 (right) ratios. Type 1 IFN‑competent cells appear in green. Mosaic images were generated by acquisition of overlapping imaging fields. Scale bars represent 25 µm. (D-E) CD86 and CD40 expression on WT (blue dots) and Irf3-/-Irf7-/- (orange dots) DCs from draining lymph nodes of mixed‑bone marrow chimeras with indicated WT:Irf3‑/‑Irf7‑/‑ ratios.
