Most neurodegenerative diseases such as Alzheimer's disease are proteinopathies linked to the toxicity of amyloid oligomers. Treatments to delay or cure these diseases are lacking. Using budding yeast, we report that the natural lipid tripentadecanoin induces expression of the nitric oxide oxidoreductase Yhb1 to prevent the formation of protein aggregates during aging and extends replicative lifespan. In mammals, tripentadecanoin induces expression of the Yhb1 orthologue, neuroglobin, to protect neurons against amyloid toxicity. Tripentadecanoin also rescues photoreceptors in a mouse model of retinal degeneration and retinal ganglion cells in a Rhesus monkey model of optic atrophy. Together, we propose that tripentadecanoin affects p‐bodies to induce neuroglobin expression and offers a potential treatment for proteinopathies and retinal neurodegeneration. The natural lipid tripentadecanoin induces the expression of Yhb1 in budding yeast and its orthologue Neuroglobin in mammals. Yhb1 induction prevents the formation of age‐induced protein aggregates and delays aging in yeast. Neuroglobin induction prevents the toxicity of diverse amyloid oligomers in neurons and chemically or genetically induced retinal degeneration in animals.
