Within the microscopic interior of every living cell, a hidden layer of self-defense has long operated beyond scientific understanding. Japanese researchers at Juntendo and Hokkaido Universities have now illuminated how cells can activate their master antioxidant switch — NRF2 — without first detecting oxidative damage, through a mechanism involving protein droplets called p62 bodies that physically trap the suppressor protein KEAP1. This discovery, published in The EMBO Journal, reveals that cellular resilience is more architecturally complex than previously known, and that the same protectiv

Scientists uncover how p62 bodies activate stress-response pathway independent of oxidative triggers
Hyperactivation of this pathway in mouse models caused hyperkeratosis and stunted growth due to malnutrition.
