Amyloid fibrils are lengthy protein aggregates that may form on their own. They are associated with a number of diseases, including Alzheimer's and Parkinson's, which are now incurable and affect a large number of people throughout the world. In this page, you will find an overview of the unique β-structure, various morphological patterns, development dynamics, and detrimental consequences of amyloid fibrils and oligomers. Several approaches to diseases caused by amyloid are shown using Alzheimer's disease as an example. In addition, the article delves into the biological and nanotechnology uses of amyloid fibrils and gives a rundown of the typical biological mechanisms that remove them and their precursors.
