It has long been recognized that elevated circulating lipid levels are among the strongest risk factors for the development of plaques within the arterial wall that are characteristic of atherosclerotic cardiovascular disease. Indeed, decades of studies have identified the deposition of low-density lipoprotein as an initiator of this disease, which coordinates the vascular and immune dysfunction that fuels the advancement of the atherosclerotic plaque. However, in the vessel wall, deposited cholesterol and fatty acids are dynamic in nature and engage signaling pathways. Shifting from metabolic-related pathways, lipid modifications and their conversion to intermediates engage signaling cascades that further perpetuate the inflammatory milieu of the atherosclerotic plaque and its progression towards the fatal end-stage events associated with cardiovascular disease, including myocardial infarction. In this review, we will cover the cellular and molecular mechanisms that preserve homeostasis and advance disease, including how lipid species induce endothelial dysfunction and drive the development of macrophage foam cells. We will additionally discuss ongoing therapeutic strategies to combat the hyperlipidemia that underlies atherogenesis. Full article
