Abstract: Provided herein are nucleic acids, recombinant adeno-associated viral particles, compositions and methods related to treating Friedreich's ataxia. In some examples, the nucleic acids, recombinant adeno-associated viral particles, compositions and methods involve use of a FXN coding sequence, a truncated FXN 3? UTR, and a promoter.

Abstract: Described are viral vectors, compositions, kits, and methods or using the vectors, compositions, kits to modulate immune response in a subject. The viral vectors include therapeutic recombinant adeno-associated viruses (rAAVs) and tolerance inducing gene therapy vectors. The therapeutic rAAVs and tolerance inducing gene therapy vectors can be used to deliver one or more therapeutic nucleic acids to the subject. The tolerance inducing gene therapy vectors induce immune-specific tolerance to the therapeutic rAAVs to improve efficacy of the therapeutic rAAVs and allow for multiple administrations of the therapeutic rAAVs with little or no associated immune response to the therapeutic rAAVs. The therapeutic rAAVs can be used to administer a therapeutic effect to the subject.
