Emergence of SARM1 as a Potential Therapeutic Target for Wallerian-Type Diseases

Wallerian degeneration is a neuronal death pathway that is triggered in response to injury or disease. Death was thought to occur passively until the discovery of a mutant mouse strain (WLDS) that was resistant to degeneration. Given that the WLDS mouse encodes a gain-of-function fusion protein, its relevance to human disease was limited. The later discovery that SARM1 promotes Wallerian degeneration suggested the existence of a pathway that might be targeted therapeutically. More recently, SARM1 was found to execute degeneration by hydrolyzing NAD+. Notably, SARM1 knockdown or knockout prevents neuron degeneration in response to a range of insults that lead to peripheral neuropathy, traumatic brain injury, and neurodegenerative disease. Here, we discuss the role of SARM1 in Wallerian degeneration and the opportunities to target this enzyme therapeutically.
