One of the hallmarks of Alzheimer's disease is the accumulation of amyloid plaques between nerve cells (neurons) in the brain. Amyloid is a general term for protein fragments that the body produces normally. Beta amyloid is a protein fragment snipped from an amyloid precursor protein (APP).

Amyloid beta (Aβ or Abeta) is a peptide of 39–43 amino acids that appear to be the main constituent of amyloid plaques in the brains of Alzheimer's disease patients. Similar plaques appear in some va...

A breakthrough discovery in mice may lead to a new treatment for Alzheimer's disease that actually removes amyloid plaques -- considered a hallmark of the disease -- from patients' brains. ... To do this, the researchers over-expressed IL-6 in the brains of newborn mice that had yet to develop any amyloid plaques,

In double transgenic mice with mutant (A246E) but not wild-type human PS1, brain amyloid peptide levels increased and resulted in amyloid plaques when the mice were only 6-9 months old, much earlier than in APP/V717I transgenic mice (12-15 months old).

The accumulation of the amyloid-beta (Abeta) peptides in amyloid plaques correlates with pathologic changes that occur in the brains of patients with Alzheimer's disease (AD). ... After purification, this reagent bound Abeta(1-40) amyloid in vitro with a K(d) of 60 nM and specifically labeled amyloid plaques in AD brains.

Amyloid plaques are sticky buildup which accumulates outside nerve cells, or neurons. Amyloid is a protein that is normally found throughout the body. For reasons as yet unknown, in AD, the protein divides improperly, creating a form called beta amyloid which is toxic to neurons in the brain.

The role of amyloid plaques in Alzheimer's; Amyloid plaques are mostly made up of a protein called B-amyloid protein which is itself part of a much larger protein called APP (amyloid precursor protein). These are amino acids.
