Tropism of adeno-associated virus serotypes in mouse lungs via intratracheal instillation.

ABSTRACT:

Background

Gene therapy holds great potential for treating various acquired and inherited pulmonary diseases. Adeno-associated viral (AAV) vectors have been thought to be primary candidates for gene delivery in patients with pulmonary diseases. However, the tropism of AAVs in the lungs remains largely unknown.

Results

Here, we investigate the tropism of twenty serotypes of AAVs by examining AAV-packed vector expression of the enhanced green fluorescent protein (eGFP) in mice. AAV1, AAV4, AAV5, AAV6, AAV6.2, AAV-PHP.B, and AAV-PHP.S exhibit high transduction rates in the airway epithelium. AAV1, AAV4, AAV5, AAV6, and AAV6.2 highly infect club cells. AAV1, AAV4, AAV5, AAV6, AAV6.2, and AAV-PHP.B efficiently infect ciliated cells. AAV8 and AAVrh10 can infect a few alveolar type
