Non-viral vectors offer a safer alternative for gene therapy, overcoming the risks associated with viral vectors. This review explores self-assembled systems using cationic polymers for effective nucleic acid delivery.

Area of Science:

  • Biotechnology
  • Molecular Biology
  • Gene Therapy

Background:

  • Nucleic acid delivery is crucial for gene therapy, enabling treatment of genetic diseases by modifying gene expression.
  • Current gene therapy primarily uses viral vectors, despite drawbacks like mutagenicity and immunogenicity.
  • The limitations of viral vectors necessitate the development of alternative, safer gene delivery systems.

Purpose of the Study:

  • To review non-viral gene delivery vectors, specifically self-assembled systems.
  • To highlight the role of cationic polymers in forming complexes with nucleic acids.
  • To discuss the challenges and transition from in vitro to in vivo gene delivery.

Main Methods:

  • Focuses on self-assembled non-viral gene delivery systems.
