Controlled release strategies for rAAV-mediated gene delivery

Area of Science:

• Gene Therapy
• Biomaterials Science
• Molecular Biology

Background:

• Efficient gene transfer vectors are crucial for clinical gene therapy.
• Recombinant adeno-associated virus (rAAV) vectors are promising but face challenges like immune responses and physiological barriers.
• Controlled release strategies offer potential solutions to enhance gene vector performance.

Purpose of the Study:

• To review recent advances in gene therapy using rAAV vectors.
• To focus on controlled release from biomaterials for improved rAAV delivery.
• To discuss challenges for clinical translation of these gene therapy approaches.

Main Methods:

• Review of current literature on gene therapy and rAAV vectors.
• Analysis of controlled release strategies employing biomaterials for gene vector delivery.
• Discussion of in vivo performance enhancement and overcoming physiological barriers.

Main Results:

• Controlled release systems can improve temporal and spatial presentation of therapeutic gene vectors.
• Biomaterial-based delivery can potentially mitigate host immune responses and physiological limitations.
• Recent advances show promise for enhanced gene transfer efficiency and safety.

Conclusions:

• Controlled release of rAAV vectors using biomaterials presents a viable strategy to address current gene therapy limitations.
• Overcoming host immune responses and physiological barriers is key for successful clinical translation.
• Further research is needed to ensure safe and efficient adaptation of these approaches in patients.
