Adeno-associated virus (AAV) is a small replication-deficient DNA virus belonging to the Parvovirinae family. It has a single-stranded ∼4.7-kb genome. Recombinant AAV (rAAV) is created by replacing the viral rep and cap genes with the transgene of interest along with promoter and polyadenylation sequences. The short viral inverted terminal repeats must remain intact for replication and packaging in production, as well as vector genome processing and persistence in the transduction process. The AAV capsid (serotype) determines the tissue tropism of the rAAV vector. In this unit we will discuss serotype selection for lung targeting along with the factors effecting efficient …

Alpha 1-Antitrypsin (AAT) deficiency is a human genetic disease resulting in the production of mutant AAT, a hepatocyte produced serine protease inhibitor that functions to prevent alveolar epithelial damage by inhibiting neutrophil elastase. Patients with AAT deficiency have increased lung disease, due to decreased proteolytic protection, as well as sporadic severe liver disease secondary to accumulation of mutant AAT, especially a common mutant form termed PiZ, within hepatocytes. We previously showed, in a PiZ mutant mouse model, simultaneous knock-down of mutant PiZ-AAT and augmentation of wild-type AAT production through intravenous delivery of a recombinant adeno-associated viral (rAAV) vector encoding both …
