title: Hypercholesterolemia links hematopoiesis with atherosclerosis.
abstract: Atherosclerosis is characterized by the progressive accumulation of lipids and leukocytes in the arterial wall. Leukocytes such as macrophages accumulate oxidized lipoproteins in the growing atheromata and give rise to foam cells, which can then contribute to the necrotic core of lesions. Lipids and leukocytes also interact in other important ways. In experimental models, systemic hypercholesterolemia is associated with severe neutrophilia and monocytosis. Recent evidence indicates that cholesterol-sensing pathways control the proliferation of hematopoietic stem-cell progenitors. Here we review some of the studies that are forging this particular link between metabolism and inflammation, and propose several strategies that could target this axis for the treatment of cardiovascular disease.
