doi: 10.1038/s41591-018-0336-8
Figure Lengend Snippet: ( a ) Expression microarray analyses of aortas. Heatmaps
show GO terms leukocyte migration, complement activation, phagocytosis, and
cellular response to lipid. 6 weeks WT (n=3 mice); 32 weeks WT (n=3); 6
weeks ApoE-/- (n=3); 32 weeks ApoE-/- (n=3); ( b ) aorta
alternative complement pathway genes (factor B, factor H, factor D) mRNA
expression in 6 weeks and 32 weeks old WT and ApoE-/- mouse aortas. 6 weeks
WT (n=3 mice); 32 weeks WT (n=3); 6 weeks ApoE-/- (n=3); 32 weeks ApoE-/-
(n=3); ( c - d ) plasma cholesterol and body weight;
( e - f ) blood leukocytes and percentage. For
c-f, control (11 mice); C5 siRNA (12 mice). ( g ) blood CD4+ T
cells, CD8+ T cells, and B220+ B cells by flow cytometry. Control (6 mice);
C5 siRNA (6 mice). ( h ) super-resolution microscopy shows
colocalization of C1q (green) and ApoE (red) in human atherosclerotic
plaque. Representative images from at least 3 biologically independent mouse
samples. Bar 5 µm. Data in b,c,d,e,f,g represent means ± SEM;
Two-tailed Student's t-test was applied to c.d.e.f.g; one-way ANOVA with
Tukey posttest was applied to b; abbreviations: WBC, white blood cells; RBC,
red blood cells; PLT, platelets; LYM, lymphocytes; MO, monocytes; GRA,
granulocytes. Gene names and statistics in .
