Pathogenetic model of neurodegenerative diseases. Decrease in transport/translation of cytoskeleton-related mRNAs results in inhibiting maintenance of structural integrity of axons, especially of growth cone or synapses, leading neuronal dysfunction and degeneration. Decrease of transport/translation of translation-related (e.g., ribosomal protein mRNAs) mRNAs or many target mRNAs causes dysregulation of overall protein synthesis in axons, which leads neuronal dysfunction and degeneration.
