The autophagy-lysosomal pathway is a self-catabolic process by which
dysfunctional or unnecessary intracellular components are degraded by lysosomal
enzymes. Proper function of this pathway is critical for maintaining cell
homeostasis and survival. Subarachnoid haemorrhage (SAH) is one of the most
devastating forms of stroke. Multiple pathogenic mechanisms, such as
inflammation, apoptosis, and oxidative stress, are all responsible for brain
injury and poor outcome after SAH. Most recently, accumulating evidence has
demonstrated that the autophagy-lysosomal pathway plays a crucial role in the
pathophysiological process after SAH. Appropriate activity of autophagy-lysosomal
pathway acts as a pro-survival mechanism in SAH, while excessive self-digestion
results in cell death after SAH. Consequently, in this review article, we will
give an overview of the pathophysiological roles of autophagy-lysosomal pathway
in the pathogenesis of SAH. And approaching the molecular mechanisms underlying
this pathway in SAH pathology is anticipated, which may ultimately allow
development of effective therapeutic strategies for SAH patients through
regulating the autophagy-lysosomal machinery.
