(A‑B) BMDCs were plated at different densities and stimulated with poly(I:C) for 24h or left unstimulated. DC activation was evaluated based on surface expression of CD86 and CD40 molecules as measured by flow cytometry. (A) Representative dot plots showing CD86 and CD40 expression. (B) Quantification of CD86 and CD40 upregulation as a fold change in geometric mean fluorescence intensity (gMFI) over unstimulated controls. Data are pooled from 3 independent experiments.
