Viral gene therapy strategies: from basic science to clinical application

Area of Science:

• Biotechnology
• Molecular Biology
• Oncology

Background:

• Gene therapy faces challenges due to inefficient and toxic gene delivery systems.
• Viruses, naturally evolved for gene delivery, are promising tools for therapeutic applications.
• Cancer treatment has seen significant advancements with gene therapy, including a licensed treatment in China.

Purpose of the Study:

• To review the current state of viral gene delivery systems for various diseases.
• To highlight the potential of viruses as non-toxic and efficient gene delivery vectors.
• To discuss the advancements and future prospects of viral gene therapy, especially in oncology.

Main Methods:

• Review of existing literature on viral vectors for gene therapy.
• Analysis of different types of virus vectors (e.g., adenovirus, retrovirus, adeno-associated virus) and their applications.
• Discussion of virus-host interactions and safety considerations.

Main Results:

• Viruses are effective gene delivery systems, offering transient or permanent transgene expression.
• Modified virus vectors allow for targeted delivery and systemic administration.
• Oncolytic viruses show promise in cancer treatment, with successful clinical trials.

Conclusions:

• Optimizing viral vector safety through understanding virus-host interactions is critical for clinical application.
• Targeted viral gene therapy, especially oncolytic virotherapy, holds significant potential for cancer treatment, particularly in combination therapies.
