Summary:
-
Lifespan Extension: A drug has been shown to extend the lifespan of laboratory mice by nearly 25%, earning treated mice the nickname “supermodel grannies” due to their youthful appearance.
-
Mechanism: Researchers focused on interleukin-11, a protein that increases with age and contributes to inflammation. Experiments involved genetically engineering mice to lack this protein and using a drug to purge it from older mice.
-
Health Benefits: Mice treated with the drug had fewer cancers, improved muscle function, healthier fur, and lower frailty scores. The study, published in Nature, is currently being tested in humans to determine if similar anti-aging effects occur.
