Webb15 jan. 2024 · The programmed axon degeneration pathway has emerged as an important process contributing to the pathogenesis of several neurological diseases. The most crucial events in this pathway include activation of the central executioner SARM1 and NAD + depletion, which leads to an energetic failure and ultimately axon destruction. WebbSARM1 is an inducible NAD + hydrolase and the central executioner of axon loss. In healthy axons, the SARM1 NADase is autoinhibited. With injury or disease, this autoinhibition is …

Webb26 mars 2015 · SARM1 function and nicotinamide mononucleotide adenylyltransferase 2 (NMNAT2) loss both promote axon degeneration, but their relative relationship in the process is unknown. Webb6 jan. 2024 · Enrichment of rare SARM1 variants in ALS patients. The discovery of single point mutations in SARM1 that confer constitutive NADase activity leading to degeneration of cultured neurons [10, 22, 23, 37] prompted us to postulate that rare human gain-of-function SARM1 variants might increase risk for neurodegenerative disease. ALS was of …
Webb1 feb. 2016 · Active degeneration requires SARM1 and MAP kinases, including DLK, while the NAD+ synthetic enzyme NMNAT2 prevents degeneration. New studies reveal that these pathways cooperate in a locally mediated axon destruction program, with NAD+ metabolism playing a central role.
