This hypothesis proposes that targeted enhancement of VPS26A subunit expression and stability can rescue retromer complex dysfunction by improving the structural integrity and assembly efficiency of the VPS26/VPS29/VPS35 heterotrimer. Unlike approaches focusing on VPS35 restoration, this strategy targets the cargo recognition subunit VPS26A, which serves as the critical interface between the retromer core and cargo-selective sorting nexins. The mechanism involves VPS26A-mediated stabilization of
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
