Amyloid fibrils in Alzheimer’s disease visualized using gold nanoparticles

Written by The Nanomed Zone, Lucy Chard, Editor

Alzheimer’s disease is one of the most common causes of dementia in older adults. It is characterized by certain pathologies, including the formation of knot-like structures – amyloid fibrils – between brain cells. The amyloid fibrils are formed from amyloid beta peptide and the Tau protein. These are both produced in the healthy brain, however, sometimes they can become tangled up forming the fibril structures, which leads to the development of neurodegenerative diseases such as Alzheimer’s. The amyloid fibrils contribute to disease progression by spreading from one brain cell to the next and are thought to degenerate neurons, which can...
