Investigating aldehyde dehydrogenase 2 polymorphism in the aging brain and Alzheimer's disease
Abstract - Mitochondrial aldehyde dehydrogenase (ALDH) 2 is primarily expressed in the liver and is crucial for the alcohol detoxifying pathway. ALDH2 also prevents the accumulation of neurotoxic and lipid-derived aldehydes. Aldehydes are end-products of oxidative stress. They can form inactive adducts with macromolecules (DNA, RNA, lipids, proteins), leading to cellular dysfunction. 10% of the World population has ALDH2 polymorphism. The most prevalent ALDH2 variant (ALDH2*2) increased neuroinflammation, mitochondrial dysfunction, and AD risk. Using primary cultures and transgenic mice, I investigate the mechanisms linking ALDH2*2 to brain aging and AD. My work suggests that ALDH2*2 is associated with reduced lipid droplet formation in response to stress. Targeting ALDH2 activity could help increase brain resilience and develop new therapies for AD.
