Pre-existing immunity to adeno-associated virus (AAV)2 limits transgene expression following intracerebral AAV2-based gene delivery in a 6-hydroxydopamine model of Parkinson's disease.
Adeno-associated virus (AAV) vectors are used to deliver potentially therapeutic genes in clinical trials in Parkinson's disease (PD). Pre-existing immunity to AAV and a local neuroinflammatory response might negatively affect the efficacy of such AAV-mediated gene delivery.
