The presence of amyloid plaque can be detected post mortem and is in tegral in the diagnosing of Alzheimers disea! se. The amyloid beta protein is itself a segment of a more larger protein known as amyloid herald protein (APP). APP is a normal neurone membrane protein that is synthesized within the cell, transported to the cell membrane and then later broken down.
