CXCL10 and atherosclerosis: Because macrophage foam cells are characteristic of atherosclerosis, we measured both plaque lipid (31.3 ± 8.0% treated versus 29.5 ± 7.0% control) and macrophage content (31.7 ± 7.6% treated versus 27.8 ± 7.0 control; Figure 1(a)), where both remained unchanged upon CXCL10 inhibition.
