Description
Cystic fibrosis is an autosomal recessive disease caused by mutations in the gene for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. CFTR is an ion channel protein that transports chloride ions across the membranes of cells that line airways, glands, and the digestive tract. This animation illustrates how cystic fibrosis mutations can prevent CFTR from functioning properly, leading to the production of a thick mucus that obstructs airways and promotes infections. After screening hundreds of thousands of small molecules, scientists have identified a drug that can improve CFTR function and treat the disease in some patients.
Depending on students’ background, it may be helpful to pause the animation at various points to discuss different structures or molecules.
