We report a new strategy for cell-type-specific delivery of functional siRNAs into cells. The method involves the noncovalent attachment of siRNAs to ligand-conjugated oligodeoxynucleotides via nucleic acid base-paired interactions. The resulting complexes can be directly applied to cells, leading to specific cellular uptake and gene silencing. The method is simple, economical, and can be easily adapted for other cell surface receptors. Here we show the application of this method for the delivery of siRNAs to folate receptor-expressing cells. Published by Cold Spring Harbor Laboratory Press.
