Despite the prospect of regulatory approval of a CFTR-targeting therapy for most CF mutations, strenuous efforts are still needed to fully comprehend CFTR structure-and-function for the development of better drugs to enable people with CF to live full and active lives.
However, CFTR modulators approved for use to date are highly expensive, which has prompted questions about the affordability of new treatments and served to emphasise the considerable gap in health outcomes for patients with cystic fibrosis between high-income countries, and low-income and middle-income countries (LMICs).
Taken together, our findings indicate that an increase in SLC26A9 expression in ductal cells of the pancreas delays the age at onset of diabetes, suggesting a CFTR-agnostic treatment for a major complication of CF.
The identification of novel proteins playing key roles in the processing of CFTR could pave the way for their use as novel therapeutic targets to provide synergistic correction of mutant CFTR for the greater benefit of individuals with CF.
In this review we focus on intestinal organoids as in vitro model for CF, enabling for CF disease classification, drug development and treatment optimization in a personalized manner, taking into account rare CFTR mutations and clinical heterogeneity among individuals with CF.
Ivacaftor improved lung function during the double-blind and open-label treatment periods in patients with CF and CFTR mutations associated with residual CFTR function (ClinicalTrials.gov, NCT01685801).
Biochemical and biophysical characterizations of three nonsense mutations of cystic fibrosis transmembrane conductance regulator (CFTR) associated with a severe form of cystic fibrosis (CF) reveal the importance and heterogenous effects of the position of the premature termination codon (PTC) on the CFTR protein function.
Cystic Fibrosis (CF) is the most common monogenic autosomal recessive disease in Caucasians caused by pathogenic mutations in the Cystic Fibrosis Transmembrane Conductance Regulator <i>(CFTR)</i> gene.
In addition, chronic inflammation characteristic of CF may contribute to growth failure via alteration in the GH-insulin-like growth factor 1 signaling and other changes in the growth plate. rhGH and new CFTR modulators may improve some growth parameters.
Cystic fibrosis (CF) is an autosomal recessive genetic disorder resulting from a mutation in the gene which encodes a cellular transmembrane protein channel known as the CF transmembrane conductance regulator.
On average, we achieved 30%-50% allelic correction in UABCs and bronchial epithelial cells (HBECs) from 10 CF patients and observed 20%-50% CFTR function relative to non-CF controls in differentiated epithelia.
