Cystic fibrosis (CF) is a genetic disorder that causes mucus to build up and damage organs in the body, particularly the lungs and pancreas. Chronic infectious or inflammatory diseases lead to amyloid infiltration and dysfunction of many organs, including the kidney, liver, heart, and gastrointestinal tract. In their physicochemical properties, amyloid fibrils are reminiscent of synthetic polymers rather than usual proteins because they are stable to the action of denaturing agents and proteases.
