Proteins behaving badly

EurekAlert!, 02/24/2012

Several neurodegenerative diseases – including Alzheimer's and ALS (Lou Gehrig's disease) – are caused when the body's own proteins fold incorrectly, recruit and convert healthy proteins to the misfolded form, and aggregate in large clumps that gum up the works of the nervous system. More recently, the research group used computer simulations to manipulate proteins in a virtual environment, testing out how easy it is for mutated proteins to misfold and propagate. Using this tool has helped the team predict the progression of hereditary ALS disease.
