Scientists at the University of Cambridge have identified a new property of essential proteins which, when it malfunctions, can cause the build up, or 'aggregation', of misshaped proteins and lead to serious diseases.
A common characteristic of neurodegenerative diseases - such as Alzheimer's, Parkinson's and Huntington's disease - is the build-up of 'misfolded' proteins, which cause irreversible damage to the brain. For example, Alzheimer's disease sees the build-up of beta-amyloid 'plaques' and tau 'tangles'.
