متن کاملSize does matter: overcoming the adeno-associated virus packaging limit
Recombinant adeno-associated virus (rAAV) vectors mediate long-term gene transfer without any known toxicity. The primary limitation of rAAV has been the small size of the virion (20 nm), which only permits the packaging of 4.7 kilobases (kb) of exogenous DNA, including the promoter, the polyadenylation signal and any other enhancer elements that might be desired. Two recent reports (D Duan et ...
متن کاملImpact of capsid conformation and Rep-capsid interactions on adeno-associated virus type 2 genome packaging.
Single-stranded genomes of adeno-associated virus (AAV) are packaged into preformed capsids. It has been proposed that packaging is initiated by interaction of genome-bound Rep proteins to the capsid, thereby targeting the genome to the portal of encapsidation. Here we describe a panel of mutants with amino acid exchanges in the pores at the fivefold axes of symmetry on AAV2 capsids with reduce...
متن کاملIn vitro packaging of adeno-associated virus DNA.
We have developed an in vitro procedure for packaging of recombinant adeno-associated virus (AAV). By using AAV replicative-form DNA as the substrate, it is possible to synthesize an infectious AAV particle in vitro that can be used to transfer a marker gene to mammalian cells. The packaging procedure requires the presence of both the AAV Rep and capsid proteins. Two kinds of in vitro products ...
متن کاملAdeno-associated virus biology.
Adeno-associated virus (AAV) was first discovered as a contaminant of adenovirus stocks in the 1960s. The development of recombinant AAV vectors (rAAV) was facilitated by early studies that generated infectious molecular clones, determined the sequence of the genome, and defined the genetic elements of the virus. The refinement of methods and protocols for the production and application of rAAV...
