Autophagy and arterial plaque. Dec 1, 2011 · Evidence is accumulating that autophagy occurs in advanced atherosclerotic plaques. However, excessively stimulated autophagy causes autophagic death in plaque cells and is detrimental. We would like to show you a description here but the site won’t allow us. Little is known about autophagy in other vascular disorders, such as aneurysm formation, arterial aging, vascular stiffness, and chronic venous disease, even though autophagy is often impaired. Autophagy is a cellular self-catabolism process, which is critical to protect cellular homeostasis against harmful conditions. Discover the cause of this issue and three lifestyle changes you can make today. Autophagy plays a complex, dual role in atherosclerosis progression. Feb 13, 2009 · Autophagy is a reparative, life-sustaining process by which cytoplasmic components are sequestered in double-membrane vesicles and degraded on fusion with lysosomal compartments. This includes removing oxidized lipids and clearing damaged mitochondria in endothelial cells and macrophages, reducing inflammation within early plaques. A growing body of evidence suggests that autophagy is stimulated in advanced atherosclerotic plaques by oxidized lipids, inflammation, and metabolic stress conditions.
