Nef Induces the Raise and Nuclear Translocation of IRF-7 in Major pDCs Initially, we evaluated the capability of these cells to internalize the recombinant protein. To this aim, key pDCs were isolated from PBMCs by good selection, utilizing BDCA-4 conjugated microbeads and assayed for their purity by FC analysis (Figure 2A). Isolated pDCs had been treated with 300 ng/mL of myrNefSF2 -AlexaFluor488 for 24h. Confocal mi12 of 35 croscopy pictures showed that Nef protein was internalized by key pDCs (Figure 2B). The observation of many fields (for any total of about 500 cells) revealed that about 30 of pDCs internalized the viral protein.Viruses 2022, 14,Figure two.

To this aim, main pDCs were treated with myrNefSF2 w.t (300 ng/mL) for six and 20 h, and with CpG A for 20 h as a positive control. Afterwards, cells had been harvested and labelled to be able to observe IRF-7 by confocal microscopy (Figure three). The images revealed that IRF-7 was elevated and, while it was primarily localized within the cytoplasm, a partial nuclear translocation was detected right after 20 h of Nef remedy. In addition, a basal expression of IRF-7 in untreated cells was observed, in agreement with 13 of 35 literature reporting that p.
