Fewer CFRD pancreas GLP-1 receptors may curb insulin secretion

People with cystic fibrosis-related diabetes (CFRD) have lower pancreatic production of the GLP-1 receptor (GLP-1R), a protein that binds the hormone GLP-1 and triggers insulin secretion, a study reported. “Signaling of GLP-1 (and its ability to enhance insulin secretion) may be impaired as a result of reduced GLP-1R availability,”…
