amyloids

Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain. The aggregation of these proteins, called metal-associated amyloids, is associated with Alzheimer's disease and other neurodegenerative conditions.

University of California, San Diego scientists have used powerful computational tools and laboratory tests to discover new support for a once-marginalized theory about the underlying cause of Parkinson’s disease. The new results conflict with an older theory that insoluble intracellular fibrils called amyloids cause Parkinson’s disease and other neurodegenerative diseases. Instead, the new findings provide a step-by-step explanation of how a “protein-run-amok” aggregates within the membranes of neurons and punctures holes in them to cause the symptoms of Parkinson’s disease.

Amyloids, associated with Alzheimer’s and other diseases, could be inspiration for tough synthetic polymers.  When most people hear the word amyloid, they immediately think of Alzheimer's disease. And indeed, it was in the brains of Alzheimer's patients that these dense protein masses were first identified. But it turns out that besides playing a role in a number of diseases, amyloids also play an important structural role in many organisms from bacteria to mammals, and might point the way to a whole new category of biologically inspired synthetic materials.
