New Technology Reveals Insights into Mechanisms Underlying Amyloid Diseases

Amyloid diseases, such as Alzheimer’s disease, type 2 diabetes, cataracts, and the spongiform encephalopathies, all share the common trait that proteins aggregate into long fibers which then form plaques. Yet in vitro studies have found that neither the amylin monomer precursors nor the plaques themselves are very toxic. New evidence using two-dimensional infrared (2D IR) spectroscopy has revealed an intermediate structure during the amylin aggregation pathway that may explain toxicity, opening a window for possible interventions, according to a report in the current issue of Biomedical Spectroscopy and Imaging.
