(A) Experimental set‑up. BMDCs cultured at low density (2x103 cells/cm2) were stimulated with poly(I:C) and IFN‑α was added at various time points. IFNAR signaling was interrupted using anti‑IFNAR1 blocking antibody at the indicated time point. BMDC activation was measured 24h after poly(I:C) stimulation by flow cytometry.
