Orkambi’s anti-inflammatory benefits seen in a real-world study

Beyond improving lung function, Orkambi (ivacaftor/lumacaftor) has potent anti-inflammatory benefits that may limit immune-related lung damage in people with cystic fibrosis (CF), according to a real-world study. Researchers found that one year of treatment significantly reduced the levels of pro-inflammatory signaling molecules in the bloodstream and airways of…

Rare CFTR-active airway cell grown from CF patients

A rare cell type that lines the airways, called pulmonary ionocytes, was successfully generated from stem cells derived from people with cystic fibrosis (CF), a study reports. Among all the cell types that line the airways, the recently discovered ionocytes, which make up about 1% of cells, have the…

Neutrophil cell subtype tied to lung function decline in stable CF

Lung function decline in adults with stable cystic fibrosis (CF) was tied to high numbers of mature low-density neutrophils, a white blood cell subtype associated with inflammatory disorders, a study suggests. While previous research showed that low-density neutrophils in CF children correlated with better lung function, the changes found…

New nanoparticles may correct genetic defects in lungs

Researchers are developing new inhalable nanoparticles designed to deliver RNA-based gene-editing therapeutics directly to the lungs, a study reports. Now shown to be effective in mice, the ultimate goal is to develop inhaled therapeutics to correct genetic defects in conditions affecting the lungs, such as cystic fibrosis (CF). “This…

Study delves into how CFTR changes its shape to be effective

Small changes in the shape of CFTR, the protein defective or absent in people with cystic fibrosis (CF), opened its gate outside the cell to allow the flow of chloride ions, a study reported. CF-causing mutations that suppress CFTR function disrupt these long-distance shape changes. By comparison, CFTR potentiator…

Environment plays big role in lung function decline in CF children

Exposure to traffic-related air pollution is an important predictor of early lung function decline in children and adolescents with cystic fibrosis (CF), a study has found. Community deprivation — reflecting poverty, housing, income, education, and health insurance coverage — was also a significant predictor of this decline in young…
