Autophagy in chronic stress induced atherosclerosis.

Atherosclerosis, a complex multifactorial disease, is the leading cause of acute cardiovascular events. Substantial evidence confirms that chronic stress plays a pivot role in the occurrence and development of atherosclerosis, but the specific mechanism remains unclear. Autophagy serves as a safeguard mechanism for sustaining cellular homeostasis via eliminating unnecessary or/and harmful components, and damaged organelles in response to various stress. An increasing number of studies indicate that autophagy plays vital roles in the development of atherosclerosis. Therefore, understanding the role of chronic stress in the regulation of autophagy may provide new insight into prevention and treatment atherosclerotic disease, especially with respect to emerging targeted therapy. In present review, we focus on changes in autophagic function under chronic stress and its relationship to atherosclerosis.
