The anti-inflammatory effect of R-DHLA-AuNCs-Zn via altering local M1/M2 subsets. ROS staining (a) and representative quantification of ROS (b) in RAW264.7 cells treated with LPS or LPS + R-DHLA-AuNCs-Zn. The CAT-like (c) and GPx-like (d) activities of R-DHLA-AuNCs-Zn after stimulation of RAW264.7 by LPS. The immunofluorescence staining (e) of iNOS and Arg-1 in RAW264.7 cells treated with LPS or LPS + R-DHLA-AuNCs-Zn. ***P < 0.001. Scale bar = 100 μm. Data presented as mean ± SD. (n = 6 /group)
