Amyloid Deposit Overview

Amyloid deposits are abnormal aggregates of proteins that accumulate in tissues and organs, disrupting their normal function. These deposits are a hallmark of a group of diseases known as amyloidoses, which can affect multiple organ systems including the heart, kidneys, liver, spleen, nervous system, and digestive tract. Amyloids are characterized by their fibrillar morphology and a cross-β-sheet secondary structure. Deposition disrupts tissue architecture and function and may lead to organ failure.
