...w this novel protein works in the brain, we may be able to target it in people with the disease. The researchers showed that the genetic change that causes overproduction of Neuregulin 1 type 4 is part of a DNA sequence called a promoter, which enables genes to be coded for proteins. A protein called a...Gilbert Foundation and American Fed for Aging Research award grants on Alzheimer's disease
