Ghosn, K. Roy | | Affilation: | The University of Texas at Austin, US | | Pages: | 350 - 353 | | Keywords: | immunotherapy, cytokine, dendritic cells, vaccine, IL-10 | | Abstract: | RNA interference mediated gene knockdown is a potential immuno-modulatory tool for tuning dendritic cells (DC) activation and function in-vivo. We have developed a novel multi-tiered delivery system for combinatorial administration of SiRNA and plasmid DNA antigens in a single gene carrier system. Our hypothesis is that, co-delivery of IL-10 specific SiRNA along with DNA antigens to the same dendritic cells would inhibit IL-10 production, enhance DC activation, antigen presentation and T cell response. Non-toxic, polyethyleneimine (PEI)-functionalized, poly(lactic-co-glycolic acid) (PEI-PLGA) microparticles co-delivering IL-10 SiRNA and DNA antigen exhibited significantly higher (p | | ISBN: | 978-1-4200-8504-4 |
