Fig. 3.

(A) Intracellular ROS staining images and (B) flow cytometry analysis of DCFH-labeled RAW264.7. Cells were subjected to different treatments. Scale bars, 100 μm. (C) Confocal images of RAW264.7 cells after incubation with 200 μg ml−1 of different NPs for 4 or 12 hours. Scale bars, 10 μm. (D to G) Enzyme-linked immunosorbent assay (ELISA) results showed extracellular expression of (D) TNF-α, (E) IL-6, (F) Arg-1, and (G) IL-10. (Data are presented as the mean ± SD; *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001).
