Amyloidosis is the general term used to refer to the extracellular tissue deposition of fibrils composed of low molecular weight subunits of a variety of proteins, many of which circulate as constituents of plasma. These deposits may result in a wide range of clinical manifestations depending upon their type, location, and the amount of deposition.

Aug 15, 2014  · We also discuss several related aspects of the AD story including why presence of beta amyloid is only a possible but not a definitive indicator of AD, details related to how beta amloid can or cannot be created via secretases, the beta-amyloid clearance role of the LDL receptor, age-related inflammaging, the role of the RAGE receptor and AB.
