( B ) FACS results of cellular uptake of RD@P and RD @PM in RAW264.7 cells. ( C ) Quantification of cellular uptake of RD@P and RD@PM in RAW264.7 cells (n = 3, ∗∗ p < 0.01). ( D ) The experimental scheme of drug targeting in vivo in the implant infection model. Representative ex vivo fluorescence images ( E ) and quantification analysis ( F ) for PBS, free RD, RD@P, and RD@PM accumulation in the silicone sheets and major organs of IAI mice at 24 h after intravenous injection (n = 3, ∗∗ p < 0.01).

Article Snippet: Mouse mononuclear macrophage leukemia cell line RAW264.7 and human umbilical vein endothelial cells line (HUVEC) were obtained from Southwest Jiaotong University (Chengdu, China) and cultured in DMEM high glucose medium and F12 medium, respectively, both of which contained 10 % FBS, at 37 °C in a 5 % CO 2 humidified environment incubator (Thermo Scientific, Sunnyvale, CA).

Figure Lengend Snippet: Immunomodulatory effects of F/R@PM on macrophages in vitro. ( A ) Typical scatter plots of macrophage surface markers CD86 (M1 macrophage marker) as detected using a flow cytometer. ( B ) Representative western blot results of the expression of CD86 protein after various treatments. ( C ) Corresponding quantitative analyses of western blot results (n = 3, ∗∗ P < 0.01). ( D ) ELISA results of cytokines (TNF- α and IL-6) secreted by RAW264.7 in different groups (n = 3, ∗∗ P < 0.01). ( E ) Counted results of phagocytized S. aureus by RAW264.7 treated in different conditions (n = 3, ∗∗ P < 0.01). ( F ) Swallowed S. aureus was observed by using TEM. Yellow arrows indicate S. aureus . (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
