Fig 5. Effects on Tregs induction of synthetic peptides of N protein of HP-PRRSV.

(A) Percentage of Foxp3⁺ cells in the gated CD4⁺CD25⁺ subpopulations of 16 synthetic peptides, which covered the whole length of HP-PRRSV N protein. (B) The dose-dependent manner of three peptides 3, 7 and 12. Data came from three independent experiments. Data analysis was done using one-way ANOVA and significant differences are shown (*P<0.05 and **P< 0.01).
