Misfolded proteins: The fundamental problem is aging

Misfolded proteins: The fundamental problem is aging: "Proteins are essential for all biological activities and the cell's health. Misfolded and damaged proteins spell trouble and are common to all human neurodegenerative diseases and many other age-associated diseases. But when do proteins start to misbehave? A Northwestern University study reports that protein damage can be detected much earlier than we had thought, long before individuals exhibit symptoms. But the study also suggests if we intervene early enough, the damage could be delayed."
