Detrimental and Beneficial Effect of Autophagy and a Potential Therapeutic Target after Ischemic Stroke

Abstract EN

Autophagy, a physiologic mechanism that promotes energy recycling and orderly degradation through self-regulated disassembly of cellular components, helps maintain homeostasis.

A series of evidences suggest that autophagy is activated as a response to ischemia and has been well-characterized as a therapeutic target.

However, the role of autophagy after ischemia remains controversial.

Activated-autophagy can remove necrotic substances against ischemic injury to promote cell survival.

On the contrary, activation of autophagy may further aggravate ischemic injury, causing cell death.

Therefore, the present review will examine the current understanding of the precise mechanism and role of autophagy in ischemia and recent neuroprotective therapies on autophagy, drug therapies, and nondrug therapies, including electroacupuncture (EA).
