Many human neurodegenerative diseases are associated with amyloid fibril formation. The human 99-residue beta(2)-microglobulin (beta2m) is one of the most intensively studied amyloid-forming proteins. Recent studies show that the C-terminal fragments 72-99, 83-89, and 91-96 form by themselves amyloid fibrils
