Plasma p‐tau217 concordance with amyloid PET among ethnically diverse older adults

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring
INTRODUCTION Commercially available plasma p‐tau217 biomarker tests are not well studied in ethnically diverse samples. METHODS We evaluated associations between ALZPath plasma p‐tau217 and amyloid‐beta positron emission tomography (Aβ‐PET) in Hispanic ...

Brain transcriptomes of zebrafish and mouse Alzheimer's disease knock-in models imply early disrupted energy metabolism

Disease Models & Mechanisms, 2022
Energy production is the most fundamentally important cellular activity supporting all other functions, particularly in highly active organs, such as brains.

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

T2 Protect AD: Achieving a rapid recruitment timeline in a multisite clinical trial for individuals with mild to moderate Alzheimer's disease

Alzheimer’s & Dementia: Translational Research & Clinical Interventions, 2022
Introduction The reporting of approaches facilitating the most efficient and timely recruitment of Alzheimer's disease (AD) patients into pharmacologic trials is fundamental to much‐needed therapeutic progress.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Mitochondrial β-amyloid in Alzheimer's disease

, 2011
This research is supported by Alzheimer's Research UK, the Wellcome Trust and the Biotechnology and Biological Sciences Research Council.It is well established that the intracellular accumulation of beta-amyloid is associated with Alzheimer’s disease and

Blind source separation to enhance spectral and non-linear features of magnetoencephalogram recordings:Application to Alzheimer's disease [PDF]

, 2009
This work studied whether a blind source separation (BSS) and component selection procedure could increase the differences between Alzheimer's disease (AD) patients and control subjects' spectral and nonlinear features of magnetoencephalogram (MEG ...

Differential effects of neurodegeneration biomarkers on subclinical cognitive decline

Alzheimer’s & Dementia: Translational Research & Clinical Interventions, 2019
Introduction Neurodegeneration appears to be the biological mechanism most proximate to cognitive decline in Alzheimer's disease. We test whether t‐tau and alternative biomarkers of neurodegeneration—neurogranin and neurofilament light protein (NFL)—add ...

Visualization of PS/γ-Secretase Activity in Living Cells

iScience, 2020
Summary: A change in Presenilin (PS)/γ-secretase activity is linked to essential biological events as well as to the progression of many diseases. However, not much is known about how PS/γ-secretase activity is spatiotemporally regulated in cells. One of

Cross‐sectional and longitudinal evaluation of plasma glial fibrillary acidic protein to detect and predict clinical syndromes of Alzheimer's disease

Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2023
Introduction This study examined plasma glial fibrillary acidic protein (GFAP) as a biomarker of cognitive impairment due to Alzheimer's disease (AD) with and against plasma neurofilament light chain (NfL), and phosphorylated tau (p‐tau)181+231.
