Repeat administration of DNA/liposomes to the nasal epithelium of patients with cystic fibrosis.

The major cause of mortality in patients with cystic fibrosis (CF) is lung disease. Expression of the cystic fibrosis transmembrane conductance regulator (CFTR) gene product in the airways is a potential treatment. Clinical studies in which the CFTR cDNA was delivered to the respiratory epithelia of CF patients have resulted in modest, transient gene expression.

Chloride secretion in the trachea of null cystic fibrosis mice: the effects of transfection with pTrial10-CFTR2.

1. An improved novel plasmid backbone, pTrial10, has been developed. We have used this vector to deliver the cDNA for the cystic fibrosis transmembrane conductance regulator (CFTR) to cells, both in vitro and in vivo, complexed with cationic liposomes.

A placebo-controlled study of liposome-mediated gene transfer to the nasal epithelium of patients with cystic fibrosis.

Cystic fibrosis (CF) is a common, serious, inherited disease. The major cause of mortality in CF is lung disease, due to the failure of airway epithelial cells to express a functional product of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. A potential treatment for CF lung disease is the expression of CFTR in the airways following gene transfer.
