Abstract

Alpha-synuclein (α-syn) is a highly conserved protein encoded by the SNCA gene and is expressed uniquely in neurons of both the central and peripheral nervous systems (CNS and PNS). α-Syn is known to cause sporadic and familial forms of Parkinson's disease (PD). However, the role for neuronal expression of α-syn in the first place remains unknown. We review and discuss recently published work that suggests a novel role for α-syn expression in neurons as a restriction factor that inhibits virus transmission from the PNS to the CNS. The potential new role for α-syn expression as a virus inhibitor may provide new approaches to understand the pathogenesis of PD and provide novel approaches to prevent and treat this common neurodegenerative disease.
