Summary

Story summary

Researchers at UC Irvine showed that injecting older mice with polyunsaturated fatty acids improved eyesight, reversing age-related decline.
The study, published in Science Translational Medicine, links the effect to fat metabolism and the ELOVL2 gene, which drives retinal fatty acid production.
The team identified genetic variants linked to faster progression of age-related macular degeneration, suggesting targeted therapies.
Future work may explore lipid metabolism's role in immune aging and blood cancers.
