Targeted RNA editing by leveraging endogenous adar using engineered rnas

a technology of rna editing and endogenous adar, which is applied in the direction of dsdna viruses, viruses/bacteriophages, genetic material ingredients, etc., can solve the problems of ectopic expression of proteins or their domains of non-human origin that have potential risk of eliciting immunogenicity, and the current adar-mediated rna editing technology has certain limitations
