## **Molecular Mechanism and Rationale**
The NAD+/SARM1 axis represents a critical metabolic checkpoint that coordinates cellular stress responses through the integration of mitochondrial and endoplasmic reticulum quality control mechanisms. SARM1 (Sterile Alpha and TIR Motif Containing 1) functions as an inducible NAD+ glycohydrolase that becomes activated during axonal injury and cellular stress conditions. Upon activation, SARM1 rapidly depletes intracellular NAD+ pools through its enzymatic
## Mechanistic Overview
TBK1-OPTN-NDP52 Phospho-Cascade Coordinates Multi-Organelle Autophagy starts from the claim that modulating TBK1, OPTN (TBC1D7), NDP52/CALCOCO2 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The TBK1-OPTN-NDP52 phospho-cascade represents a sophisticated cellular quality control network that orchestrates selective autophagy across multiple organellar compartment
