Abstract Tau aggregation characterizes a series of neurodegenerative diseases including AD and other tauopathies. The distribution of Tau deposits correlates with the loss of neurons in these neurodegenerative diseases, and Tau-induced toxicity depends on its ability to aggregate. We have used an inducible cell model to study the expression of Tau variants, the buildup of aggregates, and their removal by the autophagy-lysosomal system. Incomplete chaperone-mediated autophagy of Tau generates amyloidogenic fragments that promote aggregation. The Tau aggregates are removed from cells by macroautophagy. Thus the two autophagic pathways could become possible therapeutic targets.
