Contrary to what has been believed previously, macrophages can take up large amounts of
native unmodified LDL by receptor-independent, fluid-phase pinocytosis converting these
macrophages into foam cells. Thus, targeting macrophage fluid-phase pinocytosis should be
considered when investigating strategies to limit macrophage cholesterol accumulation in
atherosclerotic plaques.
