Advanced Glycation End Products (AGEs) are highly reactive compounds formed when proteins or lipids become non-enzymatically glycated after exposure to sugars. AGEs accumulate with age and are implicated in various chronic diseases—including Alzheimer’s disease (AD).
-AGEs bind to Aβ peptides, increasing aggregation and plaque stability.
-AGEs activate kinases like GSK-3β and p38 MAPK, promoting tau phosphorylation.
-Human brains with AD show increased AGE-modified proteins and elevated RAGE expression.
-Blocking RAGE or reducing AGEs slows cognitive decline and pathology in mice.
Strategies to Reduce AGE Burden
-Low-AGE cooking (steaming, boiling), Mediterranean diet
- reduce processed meats, sugary baked goods, and fried foods.
