Summary
Gene therapy offers new medical possibilities, but safe and effective gene delivery remains a challenge. This review explores various viral and non-viral methods for therapeutic gene transfer.
Area of Science:
- Molecular Medicine
- Biotechnology
- Genetics
Background:
- Gene therapy represents a significant advancement in modern medicine, driven by progress in molecular biology and molecular medicine.
- Early gene therapy studies faced challenges with long-term side effects, highlighting the critical need for secure and efficient gene delivery systems.
- The clinical application of gene therapy is contingent upon overcoming the primary safety concern: the reliable transfer of therapeutic genes into target cells and tissues.
Purpose of the Study:
- To review and summarize the diverse delivery routes and methods employed for gene transfer in the context of gene therapy.
- To provide an overview of both established and emerging techniques for therapeutic gene delivery, encompassing viral and non-viral strategies.
- To assess the current landscape of gene transfer technologies for basic research and clinical applications.
Main Methods:
- Review of established viral vectors, including adenoviruses, adeno-associated viruses, lentiviruses, and retroviruses, detailing their properties and applications in gene therapy.
- Examination of non-viral gene transfer methods, such as lipoplexes and naked DNA transfer, highlighting recent advancements and safety considerations.
- Exploration of novel approaches, including the use of bacteria as vectors for gene therapy or as in situ producers of therapeutic proteins.
Main Results:
- Viral vectors, particularly adenoviruses, adeno-associated viruses, lentiviruses, and retroviruses, are well-established and widely used for gene transfer.
- Advancements in lipoplex preparation and increased safety profiles are enhancing the viability of naked DNA transfer methods.
- Bacterial vector-based gene therapy represents an emerging strategy requiring further experimental validation.
Conclusions:
- The choice of gene transfer method depends on specific therapeutic goals, balancing efficacy with safety considerations.
- Continued research into optimizing delivery systems, including both viral and non-viral vectors, is crucial for the advancement of gene therapy.
- Emerging technologies like bacterial vectors show promise but necessitate rigorous evaluation before clinical implementation.
