摘要：
Alpha-Synuclein (alpha Syn), a protein highly enriched in neurons where it preferentially localizes at the pre-synapse, has been in the spotlight because its intraneuronal aggregation is a central phenomenon in Parkinson's disease. However, the consequences of alpha Syn accumulation to neuronal function are not fully understood. Considering the crucial role of actin on synaptic function and the fact that dysregulation of this cytoskeleton component is emerging in neurodegenerative disorders, the impact of alpha Syn on actin is a critical point to be addressed. In this review we explore the link between alpha Syn and actin and its significance for physiology and pathology. We discuss the relevance of alpha Syn-actin interaction for synaptic function and highlight the actin-depolymerizing protein cofilin-1 as a key player on alpha Syn-induced actin dysfunction in Parkinson's disease.
