Human Hepatocyte Transduction with Adeno-Associated Virus Vector

Area of Science:

• Gene Therapy
• Virology
• Hepatology

Background:

• Adeno-associated virus (AAV) vectors are advantageous for gene therapy, with liver-targeted applications progressing in clinical trials.
• Key challenges for AAV liver-targeted gene therapy include low transduction efficiency and the prevalence of neutralizing antibodies (Nabs).

Purpose of the Study:

• To describe laboratory procedures for transducing human hepatocytes with AAV vectors in vitro and in vivo.
• To provide insights for developing novel AAV mutants with enhanced liver tropism and Nab evasion capabilities.

Main Methods:

• Detailed laboratory protocols for applying AAV vectors to human hepatocytes.
• In vitro and in vivo experimental models for evaluating AAV transduction efficiency and tropism.

Main Results:

• Established procedures for AAV vector transduction of human hepatocytes.
• Provided practical tips derived from experimental experience.

Conclusions:

• Pre-clinical evaluation using hepatocyte models is crucial for advancing AAV liver-targeted gene therapy.
• This work facilitates the development of improved AAV vectors for clinical applications, overcoming current limitations.
