How USP7 Unlocks Your Cells’ Antioxidant Defence System

USP7 is a molecular gatekeeper that frees the NRF2 antioxidant switch from suppression, allowing cells to rapidly activate their defence against free radical damage. Understanding how this system works reveals how cells rapidly respond to oxidative stress and why this response often fails during ageing.

How Brain Cells Activate Their Emergency Defence System

Brain cells use NRF2 as a master switch that activates over 200 protective proteins when oxidative stress threatens cellular machinery. This ancient defence system varies dramatically across brain regions and declines with age, affecting how well neurons survive metabolic challenges.
