Alpha-synuclein (α-syn) is a protein composed of 140 amino acids and encoded by the SNCA gene, and its main function is the transport and stabilization of synaptic vesicles, mainly in dopaminergic neurons. α-syn has been found to play an important neurotoxic role in the pathogenesis of PD, also being the major component of Lewy bodies. α-syn exists in equilibrium in its soluble forms and in its membrane-bound conformations. However, an alteration of this equilibrium causes it to aggregate forming oligomers, which are the main neurotoxic species of α-syn and which, through mechanisms of mitochondrial, metabolic, and inflammatory response alteration lead to cell injury and death. The α-syn can spread in a prion-like manner, therefore pathological forms of α-syn can be detected in many tissues outside the CNS. Different studies seek the best method and location of measuring α-syn levels in order to have an effective diagnostic method to detect PD. Naturally, α-syn is also the focus of numerous investigations with the objective of being able to treat the disease in a curative way by reducing its aggregation, increasing its degradation or limiting its spread to other cells. Studies focused on diagnostic methods and those focused on curative therapies are having promising results, but further research is needed in this regard.
