The pneumology sector has become increasingly dynamic over the last few years in the treatment of cystic fibrosis. Research has borne fruit and a highly original form of treatment has recently been developed, a potentiator of the gene in question in this terrible pathology. While this new therapy can unfortunately only be given to patients who are carriers of a certain mutation of the gene, it nevertheless offers a lot of hope to all those young patients suffering from cystic fibrosis and their families desperate for future treatments for this disease.
