An imaging agent reveals aggregated tau protein in the brain during PET scans and could improve the diagnosis of neurodegenerative diseases, particularly tauopathies.
New studies show that elevated levels of a form of tau called p-tau217 can accurately distinguish Alzheimer’s disease from other forms of dementia, and perhaps even predict it.
In brain samples from people with Alzheimer’s disease, the protein aggregates more strongly bound proteins involved in processing RNA, the same study finds.
A study hints that it might be possible to diagnose chronic traumatic encephalopathy, a neurodegenerative disease associated with frequent head injuries, while patients are still living.
Levels of tau, amyloid-β 42, and IL-10 extracted from extracellular vesicles that started out in the brain were higher in military personal suffering head injuries compared with healthy soldiers.
