Impaired autophagy-lysosome function is a convergent mechanism across neurodegenerative diseases, making pathway-level intervention attractive. However, nodes of failure differ: CMA (LAMP2A) declines in PD, bulk autophagy (Beclin-1) is impaired in AD, and lysosomal biogenesis (TFEB) shows compensatory increases in some contexts. Identifying the most disease-agnostic node guides drug development.
Multiple NDDs converge on autophagy-lysosome dysfunction. Are there universal therapeutic targets?
