Specialized functions of macrophages have evolved to protect the body from infection. However, the same mechanisms that enable phagocytosis of pathogens and activation of leukocytes also permit the uptake of lipoproteins and release of reactive oxygen species and immune mediators that collectively contribute to atherosclerosis. New approaches to inhibit lipid accumulation in macrophage foam cells and reduce inflammatory responses may be of therapeutic value in preventing coronary artery disease.
