Exosomes for miRNA Delivery

Online Inquiry

Exosomes have several advantages over conventional delivery modalities. In contrast to established liposome formulations, exosomes are natural transporters and therefore less toxic or immunoreactive. Moreover, their stability in the blood, their ability to cross biological barriers such as the blood-brain barrier (BBB), and their inherent targeting properties, make exosomes an ideal system for nucleic acid drug delivery. These nanoparticles have shown potential for therapeutic delivery of microRNAs (miRNAs). miRNA is a small molecule that can be readily transfected into exosomes to prevent degradation by nucleases in the bloodstream. miRNA-loaded exosomes have shown the potential for a variety of disease treatments, including neurodegenerative diseases, cardiovascular disease, cancer, and so on.

Exosomes as carriers for miRNA delivery systems

miRNAs are small single-stranded RNA molecules ranging in length from 21 to 25 nucleotides. As a common non-coding RNA, miRNA is known to bind to partially complementary mRNA sequences to promote their degradation or translation inhibition, thereby regulating various physiological and pathological activities. In particular, there is growing evidence that miRNAs are highly associated with cancer development and/or progression. Tumor cells have been observed to release exosomes containing miRNA, and miRNAs secreted by donor cells can be taken up by recipient cells and act on them. Therefore, these small non-coding RNAs have been considered to be powerful tools for the effective treatment of different diseases and disorders. It is confirmed that exosomes can enrich specific endogenous miRNAs and regulate lipid metabolism, promote angiogenesis and apoptosis in cancer cells, and other physiological processes. Exosomes loaded with miRNAs have been proven to have good performance in regenerative medicine, cancer, neurodegenerative diseases, and cardiovascular disease treatment.

Exosomes for miRNA Delivery

Support of exosomes as miRNA carriers

Exosomes are natural carriers of miRNAs and can be exploited as nucleic acid drug delivery systems. As the expectations for the clinical application of exosomes are increasing, Creative Proteomics provides exosome research and analysis services for further research and development of exosomes as a next-generation drug delivery system. Since the application of exosomes as a drug delivery system is in its infancy, we offer a variety of exosome purification methods and analytical techniques. Our exosome isolation and purification services are flexible and customized to support the production of high-yield and pure intact exosomes suitable for subsequent loading of genes and drugs, including miRNAs.
