Researchers at the University of California, Irvine (UC Irvine) have found that supplementing a specific polyunsaturated fatty acid improved visual performance in older mice. The study builds on the role of the ELOVL2 gene in lipid metabolism and aging, suggesting a potential pathway to slow or reverse age-related vision decline and prevent conditions like macular degeneration.
Facts First
- Researchers injected older mice with a specific polyunsaturated fatty acid and observed improved visual performance.
- The study focuses on the ELOVL2 gene, a marker of aging involved in producing fatty acids essential for vision.
- Age-related changes in lipid metabolism reduce levels of critical fatty acids in the retina, worsening vision.
- Genetic variants in the ELOVL2 enzyme are associated with faster progression of age-related macular degeneration (AMD).
- Related research suggests lipid supplementation could counteract aging in the immune system and may play a role in blood cancers.
What Happened
A research team from the University of California, Irvine (UC Irvine), along with collaborators from the Polish Academy of Sciences and the Health and Medical University in Potsdam, Germany, published findings in the journal Science Translational Medicine. The study showed that injecting older mice with a specific polyunsaturated fatty acid improved their visual performance. The work builds on previous research regarding the Elongation of Very Long Chain Fatty Acids Protein 2 (ELOVL2) gene, which is a marker of aging. Earlier research had shown that increasing ELOVL2 activity in older mice raised levels of the omega−3 fatty acid docosahexaenoic acid (DHA) in the eye and improved visual function.
Why this Matters to You
Changes in eyesight are a common sign of aging. As the body ages, changes in lipid metabolism reduce levels of very-long-chain polyunsaturated fatty acids (VLC-PUFAs) in the retina, which are essential for maintaining healthy vision. This research suggests a potential treatment pathway to slow or reverse this process. If future human trials are successful, you may have access to therapies that could help preserve your vision as you age. Furthermore, related research involving UC San Diego found that a lack of ELOVL2 can accelerate the aging of immune cells, suggesting that lipid supplementation could counteract age-related changes in the immune system and may play a role in blood cancers.
What's Next
The research team is continuing to study how lipid metabolism affects aging. In collaboration with scientists at UC San Diego, Skowronska-Krawczyk is studying how lipid metabolism affects aging in the immune system. The findings from mouse studies will need to be validated in human trials, which could take several years. Successful translation of this research could lead to new dietary supplements or medical treatments designed to maintain fatty acid levels and support healthy vision and immune function in older adults.
