Gene therapy is a process in which a new, correct version of the CFTR gene would be placed into the cells in a person's body. Cystic fibrosis should be an ideal candidate for gene therapy, for four main reasons: (1) it is a single gene defect; (2) it is a recessive condition, with heterozygotes being phenotypically normal (suggesting gene dosage effects are not critical); (3) the main pathology is in the lung, which is accessible for treatment; and (4) it is a progressive disease . A disadvantage is that we may have limited control over where the new copy of the CFTR gene integrates into the genome. The foundation is ready to invest up to $110 million to move therapy candidates into clinical testing, starting with an initial $20 million investment.

Theoretically, cystic fibrosis transmembrane conductance regulator (CFTR) gene replacement during the neonatal period can decrease morbidity and mortality from cystic fibrosis (CF). From there, either the cell incorporated the correct version of the CFTR gene (integrating gene therapy), or it temporarily uses an attached copy (non- integrating gene therapy). Gene therapy of CF lung disease. Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene that encodes a cAMP-regulated anion channel.Although CF is a multi-organ system disease, most people with CF die of progressive lung disease that begins early in childhood and is characterized by chronic bacterial infection and inflammation. Cystic fibrosis affects around 70,000 people worldwide. Cystic fibrosis (CF) is an autosomal recessive disease that affects over 70 000 people in the United States and Europe. Although the viability of cystic fibrosis (CF) gene transfer to airway epithelium has been demonstrated in vitro and in animal models, so far none of the clinical investigations using adenovirus, adeno-associated virus, lentivirus, cationic lipids or polymers has shown a persistent correction of the ion transport defects that occur in CF. Gene therapy is a revolutionary treatment in which new genetic material is introduced in a person's cells to treat or prevent rare genetic disorders. Abstract. Cystic Fibrosis (CF) is an autosomal monogenic recessive genetic disorder that affects over 70,000 individuals in the United States and Europe [].Mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene alter its function as a cyclic AMP-dependent chloride anion channel.This protein distributes mainly in epithelial cells of different organ systems, such as respiratory . Intensive basic research over the last 20 years has resulted in a wealth of information regarding the CF gene, its protein product and the mutational basis of disease. Cystic fibrosis (CF) is the most common autosomal recessive genetic disease in the US, affecting up to one in 3,500 live births.

Cystic fibrosis is caused by mutations in the gene responsible for producing the cystic fibrosis transmembrane conductance regulator (CFTR) protein. Patients with CF suffer a wide range of pathological consequences of the disease including pancreatic insufficiency, with subsequent malabsorption and impaired nutrition, and chronic lung infection with Pseudomonas aeruginosa and other pathogens [1-4]. An important goal for cystic fibrosis (CF) gene therapy is to achieve long-term functional correction. Dr. McCray also focuses on integrating vector systems for the treatment of inherited diseases, including gene transfer to airway epithelia for cystic fibrosis. Introduction.

Cystic fibrosis (CF) is a chronic autosomic recessive syndrome, caused by mutations in the CF Transmembrane Conductance Regulator (CFTR) gene, a chloride channel expressed on the apical side of the airway epithelial cells. Cystic fibrosis (CF) is a monogenic autosomal recessive disease. The principal cystic fibrosis mutation in which phenylalanine at amino acid position 508 is deleted. We plan to: 1) To study the determinants of gene delivery; 2) Examine the mechanism by which non-viral vectors transfect cells; and 3) Explore approaches to enhance gene delivery. Mutations in CFTR, the gene encoding the epithelial ion channel that normally transports chloride and bicarbonate, lead to impaired mucus hydration and clearance. The lack of CFTR activity brings a dysregulated exchange of ions and water through the airway epithelium, one of the main aspects of CF lung disease pathophysiology.
