Despite advances in conventional treatments for cystic fibrosis (CF), the disease is still associated with significant morbidity and mortality. The cloning of the cystic fibrosis transmembrane conductance regulator (CFTR) gene and the understanding of the functions of the CFTR protein have led to the development of novel treatment strategies, including gene therapy. Here, we review the underlying molecular defect in CF cells, and the progress in gene-transfer studies from in vitro work through to clinical trials. We discuss the problems encountered, the end-points used to assess efficacy, and the likely future directions of the field.
