The Committee for Medicinal Products for Human Use (CHMP) issued a positive recommendation for the commercialization of Quinsair (240 mg) as a therapeutic for adult patients with cystic fibrosis with recurrent infections by Pseudomonas aeruginosa. Cystic Fibrosis (CF) is an inherited disease that is characterized by defective mucus secretions…

In a recent study entitled “Modulation of the Maladaptive Stress Response to Manage Diseases of Protein Folding,” a team of researchers showed that in protein misfolding diseases, such as cystic fibrosis and Alzheimer’s disease, the cells’ response to misfolding proteins can actually exacerbate the disease phenotype. The study was published in the …

Cystic Fibrosis (CF) is caused by mutations in the Cftr gene (short for cystic fibrosis transmembrane conductance regulator). The CFTR protein is responsible for transporting chloride and sodium ions in and out of lung and intestinal epithelium cells, and so in the absence of CFTR functional protein, thick mucus…

In a recent study entitled “Subnanometre-resolution electron cryomicroscopy structure of a heterodimeric ABC exporter” published in the online issue of Nature, the authors determined the structure of an ABC transporter protein with a sub nanometer resolution for the first time. The new findings has implications in…

The European Medicines Agency (EMA) recently reviewed products containing the antibiotics colistin or colistimethate sodium (known as polymyxins) and recommended alterations to product sheet information to include safety and the most updated information when applied to treating infections that demonstrated to be resistant to other standard antibiotics. This update…

A new study from Karolinska Institute entitled “Interleukin-26 in Antibacterial Host Defense of Human Lungs: Effects on Neutrophil Mobilization” and published in the American Journal of Respiratory and Critical Care Medicine describes a new mechanism of antibacterial defense in the lungs, mediated by…

A new study entitled “Inter- and Intraspecies Metabolite Exchange Promotes Virulence of Antibiotic-Resistant Staphylococcus aureus” published in Cell Host & Microbe reports antibiotic-resistant Staphylococcus aureus interacts with other species to promote their growth and virulence inside its host. This new finding is particularly important to the…

A new study entitled “Counteracting suppression of CFTR and voltage-gated K+ channels by a bacterial pathogenic factor with the natural product tannic acid” published in Elife reports on the discovery of an inhibitor for Staphylococcus aureus, the leading agent of infections in Cystic Fibrosis…

This year at the 28th Annual North American Cystic Fibrosis Conference (NACFC) in Atlanta, Vertex Pharmaceuticals Incorporated announced their ongoing efforts to treat the underlying cause of cystic fibrosis (CF) by focusing on mutations in the CFTR gene (short for cystic fibrosis transmembrane conductance receptor) through a combination of drugs.

A new study entitled “Self-reported exercise and longitudinal outcomes in cystic fibrosis: a retrospective cohort study” published in October issue of BMC Pulmonary Medicine suggests that self-reported exercise improves nutritional and pulmonary outcomes in adults with cystic fibrosis. Cystic Fibrosis is a life-threatening disease, characterized…
