Plasma biomarkers for Alzheimer's disease: a field-test in a memory clinic

Aurélien Lathuilière, Sara Stampacchia

Background The key Alzheimer's disease (AD) biomarkers are traditionally measured with techniques/exams that are either expensive (amyloid-positron emission tomography (PET) and tau-PET), invasive (cerebrospinal fluid A beta 42 and p-tau 181), or poorly sp ...

Stroke and Amyloid-beta Downregulate TREM-2 and Uch-L1 Expression that Synergistically Promote the Inflammatory Response

Ivan Enrico Repetto

Neuroinflammation is involved in the pathogenesis of Alzheimer's disease, and the transcription factor NF-kappa B is a player in this event. We found here that the ischemic damage alone or in association with A beta(1-42) activates the NF-kappa B pathway, ...
