Quantification of human mature frataxin protein expression in nonhuman primate hearts after gene therapy

Ian Blair, Teerapat Rojsajjakul, Juliette Hordeaux et al. Quantification of human mature frataxin protein expression in nonhuman primate hearts after gene therapy, 29 June 2023, PREPRINT (Version 1) available at Research Square doi:10.21203/rs.3.rs-3121549/v1 

Therefore, increasing expression of heart hFXN-M using gene therapy offers a way to prevent early mortality in FRDA. We used rhesus macaque monkeys to test the pharmacology of an adeno-associated virus (AAV)hu68.CB7.hFXN therapy. The advantage of using non-human primates for hFXN-M gene therapy studies is that hFXN-M and monkey FXN-M (mFXN-M) are 98.5% identical, which limits potential immunologic side-effects.
