Modified aav vectors that dampen the humoral immune response

Abstract

Provided herein are compositions of recombinant adeno-associated virus (rAAV) particles capable of dampening the humoral immune response against rAAV in the host into which the rAAV particles are introduced. The modified genomes of these rAAV particles comprise heterologous insert nucleic acid and/or inverted terminal repeat (ITR) sequences containing one or more sequences associated with the human leukocyte antigen gene complex DR (HLA-DR) promoter. Also provided herein are methods for transducing host cells with modified rAAV particles to induce a dampened humoral immune responses in order to improve transduction efficiencies. Also provided herein are complexes comprising a modified rAAV particle and a Regulatory Factor X (RFX) transcription factor.
