doi: 10.1371/journal.pone.0054625
Figure Lengend Snippet: Peritoneal macrophages from ApoE −/− mice after vitamin D-sufficient or –deficient HFD were assessed by flow cytometry for ( A ) Cell surface markers for M1 and M2 phenotype (CCR7: gray, CD86: black, MR: dots, CD163: white) and ( B ) Macrophage phenotype ratio calculated from flow cytometry analysis to assess M1 vs. M2 predominance (vitamin D-sufficient: black, vitamin D-deficient: white). From the aortic root of vitamin D-sufficient (top) and -deficient (bottom) animals after 8 weeks on HFD, ( C ) Represenative image of double immunofluorescent staining for CCR7 (M1, green), MR (M2, green), and ADRP (red). Scale bar represents 50 µm. ( D ) Quantification of CCR7 immunofluorescent staining as a percentage of total atherosclerotic plaque area, ( E ) Co-localization (yellow) of CCR7 and MR with ADRP as a percentage of ADRP-positive area (n = 3 per group for all). Data expressed as mean ± SEM. *p<0.05, **p<0.01.
Article Snippet: Macrophage cell surface marker analysis was performed using a FACStar Plus with PE-conjugated anti-CCR7 and anti-CD86 (1∶100 for both, E-Bioscience) for M1 macrophage membrane protein expression and FITC-conjugated anti-CD163 (1∶20, Bioss USA) and anti-MR (1∶100, R&D Systems) for M2 macrophage membrane protein expression .
