Abstract
Described herein is an adeno-associated virus (AAV) complex platform including an asymmetrically modified inverted terminal repeat (ITR). The AAV complex has advantages of increased productivity and expression efficiency of a transgene, and decreased genotoxicity, by having an asymmetric ITR in which any one of two ITRs is modified. Also, described herein is a composition comprising the adeno-associated virus complex and a method of gene therapy.
Claims15
An adeno-associated virus (AAV) complex, comprising a polynucleotide sequence encoding a transgene between a first inverted terminal repeat (ITR) and a second ITR, wherein in any one of the first ITR and the second ITR, all or part of a stem-loop structure, which is formed of rep-binding element (RBE), RBE′, A, A′, B, B′, C, C′, and D regions, is modified.
