One of the first stages of Alzheimer’s disease involves formation of toxic aggregates, called oligomers, of the protein amyloid beta (Aβ). These oligomers can start to form more than a decade before symptoms appear and before other known disease markers form. The ability to detect these oligomers would permit early disease diagnosis. This would make strategies to intervene before irreparable brain damage occurs possible…

Before Aβ snaps into the rigid amyloid fibrils that predominate in plaques, the peptide clumps into soluble oligomers. Deemed the most toxic form of Aβ, these fledgling aggregates have also been devilishly difficult to detect. Now, researchers led by Valerie Daggett at the University of Washington in Seattle report that a soluble-oligomer binding assay—SOBA—picks them up in plasma, distinguishing controls and people with Alzheimer’s disease with 99 percent accuracy. The assay uses a designer peptide to capture oligomers that fold into α-sheets, a secondary structure that forms in the earliest stages of oligomerization…

The formation of toxic Amyloid β-peptide (Aβ) oligomers is one of the earliest events in the molecular pathology of Alzheimer’s Disease (AD). These oligomers lead to a variety of downstream effects, including impaired neuronal signaling, neuroinflammation, tau phosphorylation, and neurodegeneration, and it is estimated that these events begin 10 to 20 y before the presentation of symptoms…

A simple blood test that can detect Alzheimer’s disease years before symptoms appear may be one step closer to reality, as researchers devise a new method to find it early. The latest test focuses on amyloid beta proteins that have misfolded and are starting to clump together in the brain, a hallmark of Alzheimer’s disease. At one time, they could only be found during an autopsy. Now they are often uncovered with advanced imaging…
