Parkinson's disease and Dementia with Lewy bodies are neurodegenerative disorders characterized by accumulation of ?-synuclein. Recently, single chain antibodies (scFV) have been developed against individual conformational species of ?-syn. Unlike more traditional mAbs, these scFVs will not activate or be endocytosed by Fc receptors. For this study, we investigated a scFV directed against oligomeric ?-syn fused to the LDL receptor-binding domain from apoB. The modified scFV showed enhanced brain penetration and was imported into neuronal cells through the ESCRT pathway leading to lysosomal degradation of ?-syn aggregates. Further analysis showed the scFV was effective at ameliorating neurodegenerative pathology and behavioral deficits observed in the mouse model of DLB/PD. Thus the apoB modification had the effect of both increasing accumulation of the scFV in the brain and directing scFV/ ?-syn complexes for degradation through the ESCRT pathway leading to improved therapeutic potential of immunotherapy.Molecular Therapy (2014); doi:10.1038/mt.2014.129.
