摘要：

RNA interference (RNAi) is induced by 21-25 nucleotide, double-stranded small interfering RNA (siRNA), which is incorporated into the RNAi-induced silencing complex (RISC) and is a guide for cleavage of the complementary target mRNA in the cytoplasm. There are many obstacles to in vivo delivery of siRNAs, such as degradation by enzymes in blood, interaction with blood components and non-specific uptake by the cells, which govern biodistribution in the body. In order to achieve the knockdown by siRNAs in vivo, many delivery systems of siRNAs based on physical and pharmaceutical approaches have been proposed. In addition, the immune responses of siRNA must be taken into account when considering the application of siRNAs to in vivo therapy. This review focuses on recent reports about delivery systems and immune responses of siRNAs.
