Description

The abstract describes that endocytic dysfunction causes redistribution of lysosomal hydrolases to early endosomes, leading to amyloid overproduction, but the mechanistic link between hydrolase mislocalization and amyloid generation is not explained. This gap is crucial for understanding amyloid pathogenesis.
