Fig. 3 IT1t blocks TLR7-mediated IFN production of circulating pDCs in PBMC cultures. IT1t blocks TLR7-mediated IFN production of circulating pDCs in PBMC cultures. (A and B) PBMCs from healthy individuals were cultured with R848 (5 μg/ml). IFN-producing cells were identified by flow cytometry. (C) Percentage of pDCs within the IFN-α+ PBMCs after R848 stimulation from six different donors. (D) Individual and (E) combined representation of the effects of AMD3100 and IT1t on R848-induced IFN-α production in the pDC fraction from PBMCs from four healthy donors. Box and whisker plots with median ± minimum to maximum. Friedman test with Dunn’s post hoc correction. “*” represents the statistical analysis comparing IT1t to the control R848 alone. “X” represents the statistical analysis comparing each concentration of IT1t to AMD3100. **P < 0.01, *P < 0.05.
