Effect of 5QCS-1GO-PDA on ROS scavenging capacity and macrophage polarization. (A) Changes in intracellular ROS levels of macrophages after oxidative stimulation. Scale bar: 100 μm. (B) CD206 and F4/80 immunofluorescence staining of macrophages treated with QCS, 5QCS-1GO, 5QCS-1GO-PDA for 3 days. Scale bar: 100 μm. (C) Flow cytometry was used to detect the expression of macrophage membrane surface proteins. (D–J) Western blot analysis of the effect of 5QCS-1GO-PDA treatment on secreted products of macrophages. Data are represented as mean ± SD (n = 3, *p < 0.05, **p < 0.01, ***p < 0.001).
