**Molecular Mechanism and Rationale**
The molecular cascade underlying TBK1 loss-of-function-mediated synapse elimination involves a complex interplay between defective autophagy, cellular senescence, and complement-driven synaptic pruning. TBK1 (TANK-binding kinase 1) serves as a critical regulatory kinase that phosphorylates key autophagy receptors, including OPTN (optineurin) at Ser177 and p62/SQSTM1 at Ser403. These phosphorylation events are essential for the recruitment of LC3-II to autop
## Mechanistic Overview
TBK1 Phosphorylation State Creates Phospho-Regulated Peripheral Retention Threshold starts from the claim that modulating TBK1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "## Mechanistic Overview TBK1 Phosphorylation State Creates Phospho-Regulated Peripheral Retention Threshold starts from the claim that modulating TBK1 within the disease context of neurodegeneration can redirect a disease-relev
