| Research Abstract |
In this study, to develop the intradermal siRNA delivery system using functional peptides, the intradermal siRNA delivery and therapeutic effect of siRNA in atopic dermatitis (AD) induced mice were investigated. Combination of cell-penetrating peptide and tight junction opener increased the intradermal siRNA delivery andtherapeutic effect of anti-NF kB siRNA in AD mice. In addition, the therapeutic effects by functional peptides/siRNA containing hydrogel increased compared with the peptides/siRNA solution.
