Abstract |
The challenge for alpha-1-antitrypsin (AAT also known as SERPINA1) gene therapy is to achieve long term and high levels of AAT production. Recombinant adeno-associated virus (rAAV) vector has several advantages for AAT gene delivery including no viral genes in the vector, no requirement of integration for long-term transgene expression, low immunogenicity, and wide tropism. AAV-mediated AAT gene therapy has been developed and tested in animal models for AAT deficiency, type 1 diabetes, rheumatoid arthritis, and osteoporosis. AAV-mediated AAT gene therapy has also been tested in clinical studies and has shown promising results. Here we describe the methods of rAAV-AAT vector construction and production as well as AAT gene delivery through (1) liver-directed, (2) muscle-directed, and (3) mesenchymal stem cell (MSC)-mediated routes. We will also describe methods for the evaluation of AAT expression for each delivery approach. |
