Inhibited proliferation of T. gondii in the Tg-DC-Exo treatment and miR-155-5p transfection groups. The T. gondii B1 gene copies were quantified with qPCR. a The RAW264.7 cells were treated with 120 µg/ml Tg-DC-Exo or DC-Exo for 24 h and then infected with T. gondii for 24 h. The RAW264.7 cells were transfected with miR-155-5p mimics (b) or miR-155-5p inhibitors (c) for 24 h and then infected with T. gondii for 24 h; the mimic control transfection and mock cells were set as negative controls. SPSS software was used for statistical analysis. One-way ANOVA was used for between-group comparisons, and Tukey’s multiple-group test was used for multiple-group comparisons. Each experiment was carried out three times (*P < 0.05, ***P  < 0.001)
