Gene Therapy Advances with Extracellular Vesicles

Strategic Insights -

A new approach to gene therapy has emerged, offering hope for the treatment of previously incurable diseases such as genetic disorders, cancers, and autoimmune diseases. Extracellular vesicles (EVs) have been designed as non-viral carriers for gene delivery, leveraging their ability to transport multiple cargo types, including transgenes, RNA, DNA, and proteins. This review outlines the application of EVs in gene therapy, exploring their potential for targeted delivery and cargo release.

Key Takeaways:

  • Gene therapy has brought hope for the treatment of previously incurable diseases, but its delivery remains challenging due to limited targeting and cargo-loading capacity of viral delivery vehicles.
  • Extracellular vesicles have been designed as non-viral carriers for gene therapy, offering immunologically neutral and biocompatible delivery options.
  • EVs can facilitate different gene-therapy approaches by transporting multiple cargo types, including transgenes, small encoding or non-coding RNA, DNA, and functional proteins.
  • Researchers have outlined the design of EVs for the loading of gene-therapy tools, targeted delivery, and cargo release.
  • The application of EVs in gene therapy has potential for targeted delivery and reduced toxicity.
  • Clinical applications of EVs in gene therapy are being explored to treat diseases such as cancer, genetic disorders, and autoimmune diseases.
