Molecular mechanisms of autophagy-lysosomal pathway dysfunction in neurodegenerative diseases and therapeutic strategies for lysosomal repair: a review

Xianguo Meng
The autophagy-lysosomal pathway (ALP) is a critical intracellular protein degradation system responsible for maintaining proteostasis and metabolic balance within cells. Dysfunction of this pathway has been increasingly recognized as a key pathological basis underlying various neurodegenerative diseases (NDs). This review provides a comprehensive overview of the molecular mechanisms by which ALP impairment contributes to defective protein degradation in neurodegeneration. We focus on the impact
