From Focal Lipid Storage to Systemic Inflammation

P Libby, GK Hansson. Keywords: inflammation; LDL cholesterol; smooth muscle cell

ABSTRACT


Concepts of atherogenesis have evolved considerably with time. Early animal experiments showed that a cholesterol-rich diet could induce fatty lesion formation in arteries. The elucidation of lipoprotein metabolism ultimately led to demonstrating the clinical benefits of lipid lowering. The view of atheromata as bland accumulations of smooth muscle cells that elaborated an extracellular matrix that could entrap lipids then expanded to embrace inflammation as providing pathways that could link risk factors to atherogenesis. The characterization of leukocyte adhesion molecules and their control by proinflammatory cytokines, the ability of chemokines to recruit leukocytes, and the identification of inflammatory cell subtypes in lesions spurred the unraveling of innate and adaptive immune pathways that contribute to atherosclerosis and its thrombotic complications. Such pathophysiologic insights have led to the identification of biomarkers that can define categories of risk and direct therapies and to the development of new treatments.
