Abstract:
Autophagy is a degradation process of intracellular composition.It can be divided into four different stages,including initiation,elongation,maturation and autophagosome breakdown.Its role is associated with the degree of cell damage.Moderate activation of autophagy in the case of starvation and hypoxia can promote cell survival; whereas excessive activation during cerebral ischemia can cause cell lysis and promote cell death.Preconditioning may produce ischemic tolerance by appropriate activation of autophagy.Autophagy is strictly regulated by a variety of protein kinases,apoptotic molecules and oxidative stress pathways.
