Abstract

Parkinson's disease is a neurodegenerative disorder characterized by the misfolding and aggregation of alpha-synuclein, leading to dopamine neuron death and motor function impairment. Despite its significance, the molecular mechanisms underlying alpha-synuclein's role in Parkinson's disease remain poorly understood. This study employed molecular dynamics simulations to investigate the structural and dynamic properties of alpha-synuclein in its monomeric and aggregated forms. Our results reveal that alpha-synuclein's aggregation propensity is driven by specific residue interactions, leading to the formation of toxic oligomers. Furthermore, we identified key conformational changes associated with alpha-synuclein's misfolding, which may contribute to its neurotoxicity. Our findings provide new insights into the molecular mechanisms of alpha-synuclein's role in Parkinson's disease, highlighting potential therapeutic targets for disease modification.
