Drosophila Model Reveals Cholinergic Modulation Of CF Gut
Researchers led by Lane et al. publish in PLoS Genetics on February 17, 2026, that enterocyte-specific knockdown of Cftr in Drosophila reproduces intestinal cystic fibrosis phenotypes, including reduced motility, nutrient malabsorption, and decreased energy stores. Single-nuclei RNA-seq revealed upregulation of acetylcholine esterase (Ace) and diminished cholinergic sensitivity; genetic Ace knockdown and modulation of Fork head (Fkh) restored signaling and rescued multiple gut phenotypes.
Key Points
- 1Demonstrates enterocyte Cftr knockdown reproduces reduced motility, malabsorption, and decreased energy stores in Drosophila
- 2Identifies upregulation of acetylcholine esterase (Ace) reducing cholinergic signaling via snRNA-seq in CF model gut
- 3Shows Ace knockdown and Fkh modulation restore cholinergic signaling and rescue multiple CF-associated gut phenotypes
Scoring Rationale
Novel Drosophila mechanistic study with peer-reviewed credibility; limited translational relevance and low relevance to data science.
