CFTR RNA- and DNA-based therapies.

This review provides an update on recent developments of RNA- and DNA-based methodologies and their intracellular targets in the context of cystic fibrosis (CF) lung disease. Ultimately, clinical success will require a suitable delivery system, but since the cargo for all these strategies is nucleic acid, it should hopefully be possible to exploit delivery breakthroughs from one study and apply these innovations to other experiments in order to identify the best strategy for everyone with CF. Ultimately, it may be the same approach for everyone, or possibly a number of different strategies tailored to particular mutations or classes/groups of mutations. And whilst the current focus is on CF lung disease, in the longer term the goal is to treat all affected organs in people with CF such as the pancreas, gut, and liver.
