Dissertations | Treating Cystic Fibrosis with Gene Therapy ... An effective gene transfer approach for the treatment of CF lung disease is not however imminent: low transfection efficiency and poor maintenance of gene expression are so far the main obstacles on this therapeutic path.
Gene therapy for cystic fibrosis CF occurs as a result of a defect in whats called the cystic fibrosis transmembrane conductance regulator gene, or CFTR gene.
New approaches to genetic therapies for cystic fibrosis Cystic fibrosis is caused by mutations in the gene that encodes the cystic fibrosis transmembrane conductance regulator (CFTR). Another potential risk with some viral vectors is delivery of an integrating vector to the gonads, which could be passed to future generations. Cystic fibrosis (CF) is an autosomal recessive disease caused by mutations in the cystic fibrosis transmembrane regulator (CFTR) gene.CFTR encodes for a cAMP regulated chloride channel located in the apical membrane of epithelial cells that catalyze the passage of small ions through the membrane. In other words, gene therapy is well suited for disorders that arise from a single gene mutation. Since the early days of its conceptualization and application, human gene transfer held the promise of a permanent solution to genetic diseases including cystic fibrosis (CF). This gene controls the movement of water and salt in and out of your bodys cells. Systemic gene delivery may therefore cause harmful side effects resulting from the delivery of gene therapy materials to, and expression of transgenes in, nontarget cells. Gene therapy is the sole treatment method which focus on eliminating the symptoms entirely and curing cystic fibrosis instead of minimizing the effects of the symptoms.
