Abstract
Exosomes are endogenous small vesicles of cells, and most mammalian cells secrete exosomes under normal and pathological conditions. Exosomes have become an important mediator of intercellular communication, acting as a carrier between membrane and cytosolic proteins, lipids and RNA cells. In recent years, small interfering RNA(siRNA) has become a promising therapeutic option for pathophysiological diseases, but poor bioavailability limits its therapeutic potential. To realize the therapeutic potential of RNA drugs, efficient, tissue-specific and nonimmunogenic delivery technologies must be developed. Several carriers have been investigated in which exosomes can be considered as promising carriers for efficient delivery of siRNA. The present review focuses on delivering knowledge about exosomes, siRNA, and capability of exosomes to act as natural carriers for siRNA delivery.
