Fig 2. Quantification of CD68-positive macrophages and monocytes.

Frozen sections through the aortic sinus of both DMSO-treated control mice and JZL184-treated mice with elevated 2-AG levels were stained for CD68 to visualize macrophages and monocytes (A, B). Positively stained areas were divided by the area of the vessel wall to obtain relative vessel infiltration (C). Data are presented as mean ± standard error of the mean; n = 13–14; **, p < 0.01, assessed by student’s t-test. Scale bar, 500 μm. DMSO, dimethyl sulfoxide; JZL184, inhibitor of monoacylglycerol lipase.
