Abstract
Exosomes are biological membrane vesicles measuring 30 to 100 nm. They contain an abundance of small molecules like tetraspanins, receptors for targeting and adhesion, lipids, and RNA. They are secreted by most biological cells, and are involved in a plethora of physiological functions including, but not limited to, transport of genetic material, modulation of the immune system, and cell-to-cell communication. It has been further reported that exosomes utilize a mechanism similar to that of viruses for gaining entry into cells. Due to their viral-like transfection efficiency and inherent biological function, compelling evidence indicates that exosomes can be used as novel delivery platforms for gene therapy. Furthermore, RNA-containing exosomes derived from cells can serve as functional genetic biomarkers for diseases. This twin modality of therapeutic and diagnostic is termed theranostics in the emerging field of nanomedicine. Hence in this review, we seek to expound on the various facets of exosomes, highlighting their significance in and relevance to nano-theranostic platforms for gene therapy.
