Engineered AAV vectors for improved central nervous system gene delivery
Adeno-associated viruses (AAV) are non-pathogenic members of the Parvoviridae family that are being harnessed as delivery vehicles for both basic research and increasingly successful clinical gene therapy. To address a number of delivery shortcomings with natural AAV variants, we have developed and implemented directed evolution-a high-throughput molecular engineering approach to generate novel...
متن کاملGene Transfer to the Central Nervous System: Current State of the Art of the Viral Vectors
Neurons in the CNS establish exceedingly complex and precise networks organised via specific synaptic connections that ultimately determine the cellular basis of cognitive processes and behaviour. This fragile and intricate circuitry presents a challenging barrier for fundamental neurobiology studies or clinical gene therapy where long-term genetic modification is wanted. Small volumes, low tox...
متن کاملRecombinant AAV-mediated gene delivery to the central nervous system.
Various regions of the brain have been successfully transduced by recombinant adeno-associated virus (rAAV) vectors with no detected toxicity. When using the cytomegalovirus immediate early (CMV) promoter, a gradual decline in the number of transduced cells has been described. In contrast, the use of cellular promoters such as the neuron-specific enolase promoter or hybrid promoters such as the...
متن کاملGene Delivery into the Central Nervous System (CNS) Using AAV Vectors
Application of gene therapies is a promising approach to the treatment of various neuro‐ logical disorders, including Parkinson's disease, amyotrophic lateral sclerosis (ALS), and lysosomal storage disorders, which are not treatable by any other means. However, the blood–brain barrier (BBB) is a key obstacle to gene delivery to the central nervous system (CNS). Adeno-associated virus (AAV) vect...
متن کاملAdeno-Associated Viral Vectors Serotype 8 for Cell-Specific Delivery of Therapeutic Genes in the Central Nervous System
Adeno-associated viruses (AAVs) have become highly promising tools for research and clinical applications in the central nervous system (CNS). However, specific delivery of genes to the cell type of interest is essential for the success of gene therapy and therefore a correct selection of the promoter plays a very important role. Here, AAV8 vectors carrying enhanced green fluorescent protein (e...
