Expression of the class A macrophage scavenger receptor ( MSR ) contributes to the uptake of modified low density lipoproteins ( LDL ) by macrophages and transformation of these cells into lipid-laden foam cells , which characterize atherosclerosis .
 ( protein: modified low density lipoproteins ( LDL ), None) , ( protein: class A macrophage scavenger receptor ( MSR ), None) , ( protein: MSR, None) , ( cell type: lipid-laden foam cells, None) , ( cell type: macrophages, None) , ( protein: LDL, None)
