Protein LY6E as a candidate for mediating transport of adeno-associated virus across the human blood-brain barrier

J Neurovirol. 2020 Oct;26(5):769-778. doi: 10.1007/s13365-020-00890-9. Epub 2020 Aug 24.

Abstract

The blood-brain barrier (BBB) is a major obstacle for the treatment of central nervous system (CNS) disorders. Significant progress has been made in developing adeno-associated virus (AAV) variants with increased ability to cross the BBB in mice. However, these variants are not efficacious in non-human primates. Herein, we employed various bioinformatic techniques to identify lymphocyte antigen-6E (LY6E) as a candidate for mediating transport of AAV across the human BBB based on the previously determined mechanism of transport in mice. Our results provide insight into future discovery and optimization of AAV variants for CNS gene delivery in humans.
