: In a healthy brain, these fragments are cleared away. In Alzheimer’s, an imbalance between protein production and clearance leads to an accumulation of Aβ42 , a particularly "sticky" form of the protein.
Amyloid protein plaques are hard, insoluble accumulations of proteins that build up in the spaces between nerve cells (neurons) in the brain. Considered a primary hallmark of Alzheimer's Disease (AD) , these plaques disrupt critical cell-to-cell communication and trigger a cascade of neurodegeneration. 1. How Plaques Form amyloid protein plaque
