ABSTRACT
RNAi-based technologies have shown biomedical potential; however, safe and efficient delivery of RNA remains a barrier for their broader clinical applications. Nucleic acid nanoparticles (NANPs) programmed to self-assemble and organize multiple therapeutic nucleic acids (TNAs) also became attractive candidates for diverse therapeutic options. Various synthetic nanocarriers are used to deliver TNAs and NANPs, but their clinical translation is limited due to immunotoxicity. Exosomes are cell-derived nanovesicles involved in cellular communication. Due to their ability to deliver biomolecules, exosomes are a novel delivery choice. In this study, we explored the exosome-mediated delivery of NANPs designed to target GFP. We assessed the intracellular uptake, gene silencing efficiency, and immunostimulation of exosomes loaded with NANPs. We also confirmed that interdependent RNA/DNA fibers upon recognition of each other after delivery, can conditionally activate NF-kB decoys and prevent pro-inflammatory cytokines. Our study overcomes challenges in TNA delivery and demonstrates future studies in drug delivery systems.
