Up-regulation of co-stimulatory molecule expression on human MDDCs.

<p>(A) Human MDDCs were stimulated for 24 h with LPS, MPL, or dLOS, and expression of HLA-DR, CD80, or CD86 on CD14-negative populations was assessed using flow cytometry (□). Unstimulated splenocytes (▪). (B) Mean fluorescence intensity (MFI) results. Data represent two independent experiments with similar results.
