Blood test for early Alzheimer’s detection
National Institutes of Health, January 10, 2023
“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.
An NIH-funded research team led by Valerie Daggett at the University of Washington developed a method to detect toxic Aβ oligomers in patients’ blood. They tested the assay, called the soluble oligomer binding assay (SOBA), on nearly 400 banked human blood plasma samples. Results appeared on December 13, 2022, in the Proceedings of the National Academy of Sciences.”
Soluble Oligomer Assay Rivals Other Biomarkers in Detecting Preclinical AD
Alzforum, December 22, 2022
“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. SOBA detected Aβ42 oligomers among controls who later developed mild cognitive impairment, suggesting it could identify people in the preclinical stage of AD. A modified version of the assay also detected α-synuclein oligomers in people with α-synucleinopathies. The study was published December 13 in PNAS.”

“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. Toxic Aβ oligomers contain a nonstandard protein structure, termed α-sheet, and designed α–sheet peptides target this main-chain structure in toxic oligomers independent of sequence.”
New Blood Test Can Identify Toxic Protein Years Before Alzheimer’s Symptoms Appear
Everyday Health, December 6, 2022
“Researchers have developed a new laboratory test that can measure levels of a “toxic” protein that is highly correlated with developing Alzheimer’s disease (AD) years before any symptoms of cognitive impairment appear. Published on December 5 in Proceedings of the National Academy of Sciences, the findings could be used to identify people at risk for AD, as well as help develop early treatments for the disease, according to researchers.
What clinicians and researchers have wanted is a reliable diagnostic test for Alzheimer’s disease — and not just one that confirms a diagnosis of Alzheimer’s, but a way to detect signs of the disease before cognitive impairment happens, says senior author Valerie Daggett, PhD, a professor of bioengineering in the University of Washington (UW) Molecular Engineering and Sciences Institute in Seattle.”
Alzheimer's test could diagnose 'disease of exclusion' a lot earlier
Fierce Biotech, December 6, 2022
“Alzheimer’s disease is a “disease of exclusion”—that is, a condition that doctors settle on only when all others have been ruled out. But what if you could take a routine blood test at your annual physical that could show you’re on the way to developing it?
And then, if nefarious proteins in the blood are detected, what if you could be prescribed an inhalable drug that neutralizes them
This is what Valerie Daggett, PhD, envisions for the future of treating Alzheimer’s disease. With her company AltPep, Daggett has developed an assay to detect disease-triggering proteins called toxic oligomers, precursors to the amyloid plaques characteristic of Alzheimer’s.”

New blood test can detect ‘toxic’ protein years before Alzheimer’s symptoms emerge, study shows
UW News, December 5, 2022
“Today, by and large, patients receive a diagnosis of Alzheimer’s only after they exhibit well-known signs of the disease, such as memory loss. By that point, the best treatment options simply slow further progression of symptoms.
But research has shown that the seeds of Alzheimer’s are planted years — even decades — earlier, long before the cognitive impairments surface that make a diagnosis possible. Those seeds are amyloid beta proteins that misfold and clump together, forming small aggregates called oligomers. Over time, through a process scientists are still trying to understand, those “toxic” oligomers of amyloid beta are thought to develop into Alzheimer’s.”

“Amyloid diseases are linked to protein misfolding whereby the amyloidogenic protein undergoes a conformational change, aggregates and eventually forms amyloid fibrils. While the amyloid fibrils and plaques are hallmarks of these diseases, they typically form late in the disease process and do not correlate with disease. Instead, there is growing evidence that smaller, soluble toxic oligomers form prior and appear to be early triggers of the molecular pathology underlying these diseases. Nearly 20 years ago, we proposed the α-sheet hypothesis after discovering that the early conformational changes observed…”

Alzheimer’s Disease Toxicity Halted by Synthetic Peptides
Genetic Engineering & Biotechnology News, April 15, 2019
Alzheimer’s disease (AD) is characterized by the formation of large, insoluble deposits, or plaques, of amyloid-β peptide (Aβ) in the brain. These plaques are generated by the aggregation of smaller, soluble clumps made up of perhaps a dozen or so Aβ monomers. Recent research indicates that it is these smaller Aβ aggregates, or oligomers, and not the larger deposits, which represent the toxic elements of AD.
