Genes are the specific DNA blueprints for life, and all genes play roles that are essential for health. But some can carry DNA variants that influence risk for disease, either by increasing or decreasing susceptibility. If a variation in a gene is very rare, it’s called a mutation. The mutation may cause disease, increase risk for a disease, protect against a disease, or have no impact on health at all.
Alzheimer’s research for many years has been dominated by a focus on Abeta “plaques,” a focus that largely has overlooked the other infamous hallmark of the disease—the tau-based neurofibrillary “tangles.” The research world recently has broadened its scope to include significant research into tau.
Cure Alzheimer’s Fund Research Consortium member David Holtzman’s latest paper has been published in the Journal of Neuroscience, addressing how Alzheimer’s plaques affect brain networks.
