Alzheimer's disease is characterized by aggregates in the brain, containing a protein called beta-amyloid. The neuropathology of Alzheimer's disease has recently been linked to the neurotoxic amyloid-β (Aβ) oligomers. The crucial role of Aβ oligomers in the early events of AD is experimentally underlined. Several recent results suggest that those oligomers may cause the death of neurons and neurological dysfunctions relevant to memory. Furthermore Aβ oligomers levels are increased in brain and cerebrospinal fluid samples from people with Alzheimer's disease. This reflects the potential of Aβ oligomers as a marker for the early diagnosis of the disease.

An international team of scientists from Germany, Sweden and the U.S. have used a new method to quantify soluble variants of aggregated beta-amyloid (Aβ oligomers) in cerebrospinal fluid by flow cytometry. "We found that patients with a greater number of Aβ oligomers in the cerebrospinal fluid had a more pronounced disease," says Dr. Alexander Navarrete Santos (the developer of this method and now employee of the Research Laboratory of the University of Halle, Department of Cardiothoracic Surgery), and first author of the study. Continue to read: sciencedaily.com
