Treat new GEN2.two cultures (Figure 8C,D). The depletion of EV content material didn’t drastically affect the cell response. Indeed, supernatants depleted of EVs maintained the capacity to activate STAT1 tyrosine phosphorylation early, soon after only 30 min, hence suggesting that most STATViruses 2022, 14,21 ofViruses 2022, 14,activating components should be secreted in no cost type and be mostly responsible for the early activation observed.22 ofFigure eight. Supernatants from Nef-treated GEN2.two cells depleted or not depleted of EVs activate STAT1 Figure 8. Supernatants from Nef-treated GEN2.two cells depleted or not depleted of EVs activate tyrosine phosphorylation of GEN2.2 cells early. GEN2.2 cells had been seeded at 1 106 cells/mL in STAT1 tyrosine phosphorylation of GEN2.2 cells early. GEN2.2 cells were seeded at 1 106 cells/mL 75 cm2 flask in 12 mL of final volume and left untreated or treated with 300 ng/mL of myrNefSF2 w.t. in 75 cm2 flask in 12 mL of final volume and left untreated or treated with 300 ng/mL of After 20 h, supernatants from control and treated GEN2.two cells were harvested and depleted or not myrNefSF2w.t. Just after 20 h, supernatants from control and treated GEN2.2 cells had been harvested and depleted of EVs bydepleted of EVs by ultracentrifugation. Completesupernatants depleted of depleted or not ultracentrifugation. Complete supernatants (A) and supernatants (A) and EVs (C) have been depleted of EVs (C) were made use of to treat fresh GEN2.two cells for the indicated time points. supernatants employed to treat fresh GEN2.2 cells for the indicated time points.
