Cystic fibrosis articles from across Nature Portfolio

A deep learning model—OrgaSegment—is presented for segmentation of individual intestinal patient-derived organoid structures from bright-field images. This enables quantification of organoid swelling and discrimination between organoids with different levels CFTR function and response to therapy.

Gene editing strategies for cystic fibrosis are challenging. Here the authors improve on their previously reported shuttle peptide noncovalently combined with Cas ribonucleoprotein (RNP), and derive the S315 peptide for delivery: they show base editing in the respiratory tract of the rhesus macaques.

Serotonin regulates mood as well as intestinal homeostasis, but its role in lung immune homeostasis is less clear. Here, Renga et al. show that serotonin regulates immune and microbial metabolic functions in respiratory pneumonia, beyond its mood regulatory function, by modulating tryptophan metabolism in the cystic fibrosis lung.

A wearable device improves the collection and analysis of sweat for the diagnosis of cystic fibrosis.
