Title
(EN) ENHANCING AAV-MEDIATED DELIVERY AND TRANSDUCTION WITH POLYVINYL ALCOHOL
(FR) AMÉLIORATION DE L'ADMINISTRATION ET DE LA TRANSDUCTION MÉDIÉES PAR AAV AVEC DE L'ALCOOL POLYVINYLIQUE
Abstract
(EN) Disclosed herein are novel methods for administration of rAAV particles having enhanced transduction properties, comprising the pre-incubation and co-administration of AAV capsids and polyvinyl alcohol (PVA). The disclosed methods of rAAV particle administration have improved efficiency in transducing mammalian liver and hematopoetic cells in vivo. The disclosed methods are suitable for use with a variety of AAV capsid serotypes and presudotypes and improve vector potency, thus lowering the concentration of rAAV particle required to achieve the desired effect. Further disclosed herein are buffers for storage and manufacturing of rAAV particles comprising PVA.
(FR) L'invention concerne de nouveaux procédés d'administration de particules de rAAV ayant des propriétés de transduction améliorées, consistant à incuber préalablement et à co-administrer des capsides d'AAV et de l'alcool polyvinylique (PVA). Les procédés décrits de l'administration de particules de rAAV ont une efficacité améliorée dans la transduction de cellules hépatiques et hématopoïétiques de mammifères in vivo. Les procédés de l'invention sont appropriés pour une utilisation avec divers sérotypes et présudotypes de capsides d'AAV présumés et améliorent la puissance de vecteur, réduisant ainsi la concentration de particules de rAAV requise pour obtenir l'effet souhaité. L'invention concerne en outre des tampons pour le stockage et la fabrication de particules de rAAV comprenant du PVA.
