Outline of Final Research Achievements |
In this study, we reported that immunostimulatory siRNA/pDAN-containing PEGylated lipoplex (PEGylated siRNAlipoplex) activates the immune system, resulting in the enhanced production of anti-PEG IgM. We revealed the contribution of toll-like receptor 7/9 to activate the innate immune system, respectively. A strategy to evade B cell-intrinsic TLR7/9 activation by siRNA/pDNA, such as chemical modification, may overcome immunological barriers to PEGylated liposome-based nucleic acid therapeutics. In addition, we showed PEG in the cosmetics may trigger anti-PEG IgM production in human. Our study gives the researchers valuable information which is useful to develop PEGylated nucleic acid based therapeutics.
