CARDIOVASCULAR DISEASE Lipids and Pathogenesis
In coronary disease, accumulation of lipids along blood vessel walls progresses into characteristic lesions that are hallmarks of the disease process. Lee et al. (see the Perspective by Plutzky) show that the inflammatory response associated with atherogenesis may hinge on a nuclear receptor called PPAR that is expressed in macrophages. PPAR appears to control the expression of proinflammatory genes in mouse macrophages, and its absence in mice caused a reduction in lesions by about 60%. This nuclear receptor may thus act as a molecular switch of the inflammatory program in macrophages and may represent a key target point for controlling disease progression.
