The lymph node gate to define DC includes autofluorescent cells that encroach on the Lineage+ subset, as previously described <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1003530#ppat.1003530-Brown1" target="_blank">[23]</a>. (B) PBMC and lymph node cell suspensions from SIV-naive animals were stimulated with iSIV or influenza virus with and without DV056 and intracellular expression of IFN-α and TNF-α in pDC was determined by flow cytometry. Positive labeling with cytokine-specific antibody as shown by the boxed areas was based on isotype control antibody. Numbers represent the percent positive cells. (C) PBMC, pDC-depleted PBMC and PBMC pretreated with DV056 were stimulated with iSIV, live SIV, influenza virus or CpG-C and supernatants were analyzed for IFN-α by ELISA. Unstimulated PBMC served as a negative control. (D) PBMC and lymph node cell suspensions were stimulated with iSIV or influenza virus and IFN-α and/or TNF-α in mDC, monocytes or macrophages were determined by flow cytometry. SSC = side scatter.</p>
