Researchers examined brain cells from mice as well as those from people who had died from Alzheimer's. They found that copper damages a molecule known as low-density lipoprotein receptor-related protein (LRP). LRP removes amyloid beta from the brain preventing a build-up of the protein, which is known to cause Alzheimer's. The research was presented this week at the annual meeting of the Society of Neuroscience in San Diego. Pictured is a polarised light micrograph of copper sulphate crystals.
