Background:

• Adeno-associated virus (AAV) vectors are widely adopted for in vivo gene transfer.
• Their safety profile and broad tissue transduction efficiency make them a preferred platform for gene therapy.
• Clinical successes have been observed for conditions like inherited blindness and coagulation disorders.

Purpose of the Study:

• To review the biology of AAV vectors.
• To discuss AAV-based gene therapy strategies for in vivo applications.
• To highlight key achievements and emerging challenges in the field, using the liver as a model.

Main Methods:

• Literature review of AAV vector biology and applications.
• Analysis of preclinical and clinical data, focusing on liver gene transfer.
• Discussion of AAV vector design and therapeutic strategies.

Main Results:

• AAV vectors demonstrate significant potential in clinical gene therapy.
• Challenges in preclinical and clinical development need to be addressed for broader application.
• The liver serves as a valuable model for understanding AAV gene transfer.

Conclusions:

• AAV vector technology is a promising platform for in vivo gene therapy.
• Overcoming existing hurdles is essential for expanding AAV's therapeutic scope.
• Continued research is vital for advancing AAV-based treatments for human diseases.
