β-amyloid (Aβ) peptides are the major components of the senile plaques that are associated with Alzheimer’s disease. In healthy individuals, Aβ peptides are present only in small quantities as soluble monomers that circulate in the cerebrospinal fluid (CSF) and blood. In Alzheimer’s patients, Aβ levels increase significantly, and they begin to accumulate as insoluble fibrillary plaques. Different Aβ species originate from proteolytic cleavage of the amyloid precursor protein (APP). It has been shown that the quantity of Aβ correlates with the clinical status of the patient and may be closely related to disease state.
