(A) IFN‑α (left) and IFN‑β (right) production by WT and Irf3-/-Irf7-/- BMDCs plated at high density (2x105 cells/cm2) and stimulated with poly(I:C) (blue dots) or left unstimulated (grey dots). Dotted lines represent the ELISA threshold of detection. Data are representative of 2 independent experiments.
