Age-related synaptic dysfunction is characterized by accumulation of damaged organelles and misfolded proteins due to compromised autophagy-lysosomal pathway efficiency. While TFEB activation increases lysosomal biogenesis, the critical bottleneck in aged synapses may be the impaired fusion between autophagosomes and lysosomes rather than lysosomal abundance alone. This hypothesis proposes that TFEB activation specifically enhances autophagosome-lysosome fusion machinery by upregulating SNARE pr
This hypothesis proposes that TFEB activation serves as a therapeutic strategy for neurodegenerative diseases by enhancing autophagy-lysosome pathway function to clear pathological protein aggregates. In neurodegenerative conditions like Alzheimer's, Parkinson's, and Huntington's disease, the accumulation of misfolded proteins (amyloid-β, tau, α-synuclein, huntingtin) overwhelms cellular clearance mechanisms, leading to neuronal dysfunction and death. TFEB, as the master regulator of lysosomal b
