Capacity of B cells, pDCs, and CD11c⁺mDCs to produce cytokines. pDCs, CD11c⁺ mDCs, and CD19⁺ B cells isolated from the same donor were cultured with TLRL plus CD40L. After 24 hours, the concentrations of IL-12 p70, IL-10, IL-6, TNF-α, and IFN-α in the culture supernatants were measured by ELISA. Data are shown as mean ± SEM of 5 independent experiments.
