ABSTRACT

Cystic fibrosis (CF) affects about 70,000 individuals worldwide, whose lives are shortened mainly due to chronic pulmonary infections resulting from impaired clearance of abnormally viscous airway mucus. The development of novel drugs targeting specific CFTR gene mutations in a precision medicine framework improved treatment, so that for patients born in 2000–2003 in the UK, the median life expectancy was estimated at around 40 years. Moreover the discovery of the CRISPR (Classes of Regularly Interspaced Palindromic Repeats) and Cas9 (Crispr-ASsociated) nuclease system opened the perspective of specifically correcting the defective CFTR gene as recently demonstrated in a model of intestinal stem cell organoids from CF patients. In the present review, we shall outline the existing state-of-art treatments and the perspectives for the precision treatment of CF opened by CRISPR.
