Chemists and biologists at Northwestern University have found a way to detect and estimate the size and structure of a miniscule toxic protein suspected of triggering Alzheimer’s disease. The findings, researchers say, could help scientists better understand the underlying mechanisms of the disease and lead to the development of new treatments that could slow or possibly arrest its progression.
The findings also could potentially be used to diagnose Alzheimer’s disease in living people instead of during an autopsy, says Amanda J. Haes, Ph.D., a co-author of the study. At present, Alzheimer’s can only be accurately diagnosed after death.
Haes, a National Research Council postdoctoral researcher at the Naval Research Laboratory in Washington, conducted this work while she was a graduate student at Northwestern under the direction of Richard Van Duyne. The findings were presented today at the 230th national meeting of the American Chemical Society, the world’s largest scientific society.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
