Definitions

  • Axonal degeneration has been identified as an important pathology in most neurodegenerative diseases. Axons are vulnerable to both mechanical injury (Wallerian degeneration) and disease (Wallerian-like degeneration). [0005] In healthy axons, SARM1’s N-terminus interacts with the TIR domain, preventing TIR dimerization and subsequent enzymatic cleavage of NAD + .
  • SARM1 N-terminus-TIR domain interaction is disrupted, allowing TIR multimerization to occur, followed by a rapid loss of NAD+ and associated axon degeneration.
