Induction of Tregs from lymphocytes co-cultured with PRRSV-infected MoDCs. (A) Representative flow cytometry profile of lymphocytes following 3 days co-culture of PBMCs with PRRSV-infected MoDCs (upper layer), and only culture with PRRSV-infected PBMCs (lower layer). (B) Percentage of Foxp3+ cells in the gated CD4+CD25+ subpopulations of PBMCs co-cultured with PRRSV-infected MoDC. (C) Percentage of Foxp3+ cells in the gated CD4+ CD25+ subpopulations of PRRSV-infected PBMCs alone. (D) Sorted CD4+CD25high cells. (E) Percentage suppression at the indicated Tregs: peripheral lymphocyte ratios. The lymphocytes exposed to Marc-145 lysate-treated MoDCs were used as negative control. The percentage of suppression was calculated as follows: % suppression = 100 × [1 − (% proliferation w/PRRSV/ % proliferation w/mock)] [35]. Data from three independent experiments. All data analysis was done using one-way ANOVA and significant differences are shown (*P<0.05 and **P< 0.01).

| Mouse anti Pig CD25, clone K231.3B2 recognizes porcine CD25, the alpha chain of the interleukin 2 receptor (IL-2Rα), also known as the low affinity Interleukin 2 receptor. The IL-2 receptor exists in three forms, the high affinity heterodimer, the intermediate affinity β monomer and the low affinity α monomer configurations. Clone K231.3B2 was clustered as CD25 at the First International Workshop to Define Swine Cluster of Differentiation (CD) Antigens (Lunney et al. 1994). Mouse anti pig CD25, clone K231.3B2 immunoprecipitates a protein of ~65-70 kDa from activated lymphocyte preparations (Bailey et al. 1992). CD25 is a 270 amino acid single pass type I transmembrane glycoprotein containing 2 Sushi domains. Low expression of CD25 is seen on resting peripheral blood mononuclear cells, rapidly up-regulated following stimulation by concanavalin A and phorbol myristate acetate, indicative of its role as an activation antigen (Bullido et al. 1999). |
