Intracellular transports and atherogenesis.

There is a great progress in understanding the cellular and molecular aspects of atherosclerosis, which is one of the leading causes of death. Yet, there are questions regarding the cellular and metabolic mechanisms that lead to atherogenesis. Among the many factors that influence this process, food plays a significant role. Among other factors that play a paramount role in atherogensis are alterations of the transport of food in enterocytes, oxysterols, development of an atherogenic serum, endothelial damage, accumulation of foam cells within the vessel wall, lysosome-ER transport, and hypertension. Here, we discuss the contribution of secretion, transcytosis, endocytosis of chylomicrons, low-density lipoproteins (LDL), very LDL, and high-density lipoproteins to atherogenesis.
