Steps in the Journey: CFTR mutation to sweat chloride concentration to survival

Associations between “salty” sweat and early mortality can be found in the scientific literature dating back to the 17th century [1], hundreds of years before a comprehensive medical description of cystic fibrosis (CF) [2]. Insightful observation of excessive dehydration and deaths among children during a 1948 New York City heat wave suggested that salt homeostasis was a fundamental cellular problem in CF [3], with identification of supranormal sweat chloride concentrations remaining fundamental to the diagnosis of CF today. Since identification of the mutated gene associated with CF (the cystic fibrosis transmembrane conductance regulator; CFTR) [4], pieces of the CF puzzle seem to have, for the most part, fallen into place.

Scientists grow ‘mini-lungs’ to aid the study of cystic fibrosis

The research is one of a number of studies that have used stem cells – the body’s master cells – to grow ‘organoids’, 3D clusters of cells that mimic the behaviour and function of specific organs within the body. Other recent examples have been ‘mini-brains’ to study Alzheimer’s disease and Continue reading Scientists grow ‘mini-lungs’ to aid the study of cystic fibrosis
