Amyloidosis: The Disease What is amyloid?

Amyloid fibrils are structures in which misfolded proteins are deposited in tissue and organs. Different proteins can be deposited as amyloid in various sites of the human body. When in a piece of tissue (a so-called biopsy) these deposits are viewed under a microscope in normal light, the material looks amorphous. However, if the same deposits are viewed under an electron microscope with higher magnification, massive amounts of small non-branching amyloid fibrils can be seen. When a biopsy is stained with Congo red dye, the deposits will stain red. A characteristic feature of amyloid is that these red deposits will turn into apple green if viewed in polarized light. When amyloid deposition leads to signs and symptoms of disease it is called amyloidosis.
