FoxP3+ and IL‐10+ frequency within CD4+ T cells was significantly higher in peritoneal exudate cell PECs and spleen cells of E. multilocularis infected (AE‐WT) mice at 4 months post‐infection (p.i.)when compared to non‐infected WT‐controls (Fig. 1A–D). The gene discussed is FOXP3; the disease is infection.
