Self-Amplifying Replicon RNA Vaccine Delivery to Dendritic Cells by Synthetic Nanoparticles
Dendritic cells (DC) play essential roles determining efficacy of vaccine delivery with respect to immune defence development and regulation. This renders DCs important targets for vaccine delivery, particularly RNA vaccines. While delivery of interfering RNA oligonucleotides to the appropriate intracellular sites for RNA-interference has proven successful, the methodologies are identical for R...
متن کاملInduction of an IFN-Mediated Antiviral Response by a Self-Amplifying RNA Vaccine: Implications for Vaccine Design.
RNA-based vaccines have recently emerged as a promising alternative to the use of DNA-based and viral vector vaccines, in part because of the potential to simplify how vaccines are made and facilitate a rapid response to newly emerging infections. SAM vaccines are based on engineered self-amplifying mRNA (SAM) replicons encoding an Ag, and formulated with a synthetic delivery system, and they i...
متن کاملNonviral delivery of self-amplifying RNA vaccines.
Despite more than two decades of research and development on nucleic acid vaccines, there is still no commercial product for human use. Taking advantage of the recent innovations in systemic delivery of short interfering RNA (siRNA) using lipid nanoparticles (LNPs), we developed a self-amplifying RNA vaccine. Here we show that nonviral delivery of a 9-kb self-amplifying RNA encapsulated within ...
متن کاملDevelopment of nucleic acid vaccines: use of self-amplifying RNA in lipid nanoparticles
Self-amplifying RNA or RNA replicon is a form of nucleic acid-based vaccine derived from either positive-strand or negative-strand RNA viruses. The gene sequences encoding structural proteins in these RNA viruses are replaced by mRNA encoding antigens of interest as well as by RNA polymerase for replication and transcription. This kind of vaccine has been successfully assayed with many differen...
متن کاملDevelopment of Delivery Strategies Facilitating Broad Application of Messenger Rna Tumor Vaccine by Development of Delivery Strategies Facilitating Broad Application of Messenger Rna Tumor Vaccine By
Genetic modification of dendritic cells with plasmid DNA is plagued with low transfection efficiencies because DNA taken up by non-dividing dendritic cells rarely reaches the nucleus. But this difficulty can be overcome by the use of messenger RNA (mRNA), which exerts its biological function in the cytoplasm and obviates the need to enter the nucleus. Since pioneering work of Boczkwoski et al.,...
