• To discuss the mechanisms, advantages, and limitations of different gene delivery vectors.
• To explore clinical considerations for lung gene therapy.

Main Methods:

• Review of existing literature on in vivo gene delivery methods.
• Analysis of viral vectors, liposomes, nanoparticles, and electroporation techniques.
• Examination of extracellular vesicles as an emerging delivery system.

Main Results:

• Four primary strategies for in vivo lung gene delivery exist: viral vectors, liposomes, nanoparticles, and electroporation.
• Each method utilizes distinct mechanisms for genetic material transport into lung cells.
• Extracellular vesicles represent a novel approach with potential benefits for cell targeting and cargo transfer.

Conclusions:

• Overcoming in vivo gene delivery challenges is essential for advancing lung gene therapy.
• The choice of vector depends on specific applications, efficacy, and safety profiles.
