An NAD+/NMN balancing act by SARM1 and NMNAT2 controls axonal degeneration

Axonal degeneration is controlled by the TIR domain NADase SARM1. In this issue of Neuron, Figley et al. (2021) reveal a key regulatory mechanism that controls SARM1’s enzymatic activity, providing insight into how NAD+ biosynthesis by the NMNAT2 enzyme protects axons, and a new therapeutic path to tune SARM1 activity.
