## **Molecular Mechanism and Rationale**
The autophagosome-lysosome fusion process represents a critical checkpoint in cellular proteostasis, with disruption of this mechanism serving as a primary driver of α-synuclein propagation in neurodegeneration. The molecular machinery governing this fusion process centers on the VPS41 protein and the HOPS (homotypic fusion and protein sorting) complex, which orchestrates the final steps of autophagy through precise membrane fusion events. VPS41 function
**Molecular Mechanism and Rationale**
The cGAS-STING (cyclic GMP-AMP synthase - stimulator of interferon genes) pathway represents a fundamental innate immune sensing mechanism that detects cytosolic double-stranded DNA (dsDNA) and initiates inflammatory responses. In the context of tauopathies, hyperphosphorylated tau protein disrupts mitochondrial integrity through multiple mechanisms, leading to mitochondrial DNA (mtDNA) release into the cytoplasm where it acts as a damage-associated molecul
