The Unified Theory of Neurodegeneration Pathogenesis, based on axon deamidation developed in this work, paves the way to controlling the occurrence and progression of neurodegenerative diseases such as Alzheimer’s and Parkinson’s through a unique, neuron-specific regulatory system that is 4E-BP2 deamidation, caused by the proteasome-poor environment in neuronal projections, consisting mainly of axons. This evidence concerns the gene EIF4EBP2 and Parkinson disease.
