Another gene therapy method involves encapsulating the healthy gene in fat molecules, called liposomes. When CF cells absorb the liposomes, the healthy gene then enters the cell. The protein-assist treatment strategy serves to correct the defective CFTR protein or at least get enough protein to the cell surface, where it can operate as a channel. Chloride channel therapies are another exciting method of correcting the defect in CF cells. Breaking or preventing this destructive cycle is a key focus for CF research.
Some studies improve or expand uses for current drugs, devices or techniques.
For instance, clinical trials of the airway clearance techniques will give physicians a valuable resource to help them determine which type of airway clearance method is best for each individual patient. 1996-1999 Cystic Fibrosis Foundation. All rights reserved.
