Sonodelivery in Skeletal Muscle: Current Approaches and Future Potential

Area of Science:

• Biomedical Engineering
• Molecular Biology
• Gene Therapy

Background:

• Current intramuscular gene delivery methods like electroporation, viral vectors, and direct DNA injection have limitations.
• These existing techniques present challenges in terms of safety, efficiency, or practicality, hindering their widespread adoption.
• Ultrasound-mediated gene delivery (sonodelivery) emerges as a promising alternative, offering advantages such as low cost, accessibility, reusability, minimal invasiveness, and safety.

Purpose of the Study:

• To provide a comprehensive overview of various ultrasound-mediated gene delivery techniques for intramuscular applications.
• To identify and discuss the current challenges and limitations associated with sonodelivery.
• To suggest future research directions for optimizing and advancing sonodelivery in gene therapy.

Main Methods:

• Review of existing literature on ultrasound-mediated gene delivery for intramuscular gene therapy.
• Analysis of different sonodelivery parameters, including ultrasound conditions and carrier materials.
• Comparison of sonodelivery efficiency and safety profiles with other gene delivery modalities.

Main Results:

• Sonodelivery is a versatile, cost-effective, and minimally invasive technique for gene delivery.
• Key challenges include optimizing diverse sonodelivery conditions and improving transfection efficiencies.
• Despite moderate efficiencies compared to some methods, sonodelivery shows significant potential.

Conclusions:

• Ultrasound-mediated gene delivery is a rapidly evolving field with substantial promise for intramuscular gene therapy.
• Further research is needed to standardize protocols and enhance transfection rates for broader clinical application.
• Sonodelivery represents a viable and advantageous alternative to conventional gene delivery methods.
