Gene therapy for lung disease

Gene therapy is a new field of medical research that has great potential to influence the course of treatment of human disease, The lung has been a particularly attractive target organ for gene therapy due to its accessibility and the identification of genetic deficits for a number of lung diseases. Several clinical trials have shown evidence of low levels of gene transfer and expression, but without any benefit to the patients involved. Thus, current studies are focusing on further research and technological improvements to the vectors. Gene therapy is now beginning to benefit from a shift in emphasis from clinical trials to the development of better tools and procedures to deliver gene therapy to the bedside.
