Fig 7. Effects of the mutant recombinant PRRSV strains on Tregs induction.

Fig 7

(A) Plaque morphology assay of the recombinant mutant strains. (B) Growth kinetics of the recombinant mutant strains. (C) Percentage of Foxp3+ cells in the gated CD4+CD25+ subpopulations of the recombinant viruses. (D) Concentrations of TGF-β in the supernatants of 3-day co-cultures. (E) Concentrations of IL-10 in the supernatants of 3-day co-cultures. All data are represented as the means ± standard deviation of three independent experiments, and data analysis was done using one-way ANOVA and significant differences are shown (*P<0.05 and **P<0.01).
