Delivery Systems for Mitochondrial Gene Therapy: A Review

Area of Science:

• Cell Biology
• Genetics
• Biotechnology

Background:

• Mitochondria are vital organelles producing cellular energy via their own genome, mitochondrial DNA (mtDNA).
• mtDNA is maternally inherited and prone to mutations due to limited repair mechanisms.
• Mutations in mtDNA are linked to various diseases, including metabolic, neurodegenerative, and endocrine disorders, as well as cancer.

Purpose of the Study:

• To review current knowledge on nanosystems for mitochondrial gene therapy.
• To provide conceptual approaches for developing effective mtDNA-based delivery systems.
• To highlight challenges and future directions for making mitochondrial gene therapy clinically feasible.

Main Methods:

• Literature review focusing on nanosystem composition, targeting, and release profiles.
• Analysis of existing research on mitochondrial DNA delivery systems.
• Synthesis of information to guide future research in mitochondrial gene therapy.

Main Results:

• Nanosystems are being developed to target and transfect mammalian mitochondria.
• Understanding the composition, targeting, and release profiles of these nanosystems is crucial.
• Progress is being made in restoring normal mitochondrial function through gene therapy.

Conclusions:

• Mitochondrial gene therapy is a promising strategy for treating mitochondrial disorders.
• Further optimization of gene encapsulation, mitochondrial targeting, and transfection is necessary.
• Advancements in delivery systems are key to achieving clinical feasibility for mitochondrial gene therapy.
