NEURODEGENERATION. Alzheimer's and Parkinson's diseases: The prion concept in relation to assembled Aβ, tau, and α-synuclein

Michel Goedert. Science. 2015.

Abstract

The pathological assembly of Aβ, tau, and α-synuclein is at the heart of Alzheimer's and Parkinson's diseases. Extracellular deposits of Aβ and intraneuronal tau inclusions define Alzheimer's disease, whereas intracellular inclusions of α-synuclein make up the Lewy pathology of Parkinson's disease. Most cases of disease are sporadic, but some are inherited in a dominant manner. Mutations frequently occur in the genes encoding Aβ, tau, and α-synuclein. Overexpression of these mutant proteins can give rise to disease-associated phenotypes. Protein assembly begins in specific regions of the brain during the process of Alzheimer's and Parkinson's diseases, from where it spreads to other areas.
