Parasitism in response to cytokine treatments and IGF-I siRNA transfection. Parasitism (median number of parasites per 100 cells) in L. amazonensis-infected RAW 264.7 cells transfected with or without 150 μM IGF-I siRNA for 6 hours and then were stimulated with IFN-γ (200 U/mL; R&D Systems, EUA), IL-4 (2 ng/mL; R&D Systems, EUA), or IL-13 (5 ng/mL; R&D Systems, EUA) for 24 (a) and 48 (b) hours. One representative experiment from three independent assays is shown. ∗p < 0.05 (ANOVA and Tukey's tests).
