Alpha-synuclein and Parkinson's disease: a proteomic view.

In this review, we report how proteomic methodologies have been used to investigate cellular and animal models of Parkinson's disease (PD), with a special focus on alpha-synuclein. PD is a complex, multifactorial neurodegenerative disease affecting approximately 2% of the population over 65 years of age, pathologically characterized by alpha-synuclein intraneuronal inclusions. Etiopathogenetic mechanisms of PD are not fully understood, although a number of factors contributing to the selective degeneration of substantia nigra neurons have been identified. Therefore, cellular and animal models of the disease have been developed to investigate single factors contributing to disease pathogenesis; for example, alpha-synuclein aggregation and altered dopamine homeostasis. Proteomic studies on cellular and animal models have not only confirmed existing theories on PD pathogenesis (mitochondrial impairment, oxidative stress, failure of the ubiquitine-proteasome system), but also allowed the discovery of new important common features of presymptomatic (or premotor) stages of PD, such as dysregulation of cytoskeletal proteins that could be involved at the origin of the disorder.[1]
