Perivascular Spaces as Determinants of Amyloid, Tau, and Vascular Biomarker Progression

Annals of Neurology, EarlyView.
Objective Magnetic resonance imaging (MRI)‐visible enlarged perivascular spaces (PVS) are markers of cerebral small vessel disease (SVD) and aging, processes implicated in both neurodegenerative and cerebrovascular pathologies. However, longitudinal positron emission tomography (PET) studies examining PVS as a mechanism underlying Alzheimer's disease ...

Modeling non-hereditary mechanisms of Alzheimer disease during apoptosis in yeast

Microbial Cell, 2015
Impaired protein degradation and mitochondrial dysfunction are believed to contribute to neurodegenerative disorders, including Alzheimer disease (AD). In patients suffering from non-hereditary AD, UBB+1, the frameshift variant of ubiquitin B,

Distribution of Big Tau Isoforms in the Human Central and Peripheral Nervous System

Annals of Neurology, EarlyView.
Objective Tau is widely studied in neurodegeneration, yet most work has focused on canonical brain tau isoforms. A longer isoform, “big tau,” produced by inclusion of exon 4a, is expressed in the peripheral nervous system (PNS) and central nervous system (CNS) regions.

Cryo-EM structure and polymorphism of Aβ amyloid fibrils purified from Alzheimer’s brain tissue

Nature Communications, 2019
Alzheimer’s disease is characterised by the deposition of Aβ amyloid fibrils and tau protein neurofibrillary tangles. Here the authors use cryo-EM to structurally characterise brain derived Aβ amyloid fibrils and find that they are polymorphic and right ...

Blood Biomarkers of Alzheimer's Disease and Patterns of Structural Brain Changes in the Community

Annals of Neurology, EarlyView.
Objective We aimed to investigate the associations between Alzheimer's disease (AD)‐related blood biomarkers and changes in brain volumes and cerebrovascular burden in community‐dwelling older adults. Methods We included 361 dementia‐free participants with a Mini‐Mental State Examination (MMSE) score ≥ 27 and without prior cerebrovascular events from a

Connecting the dots: A narrative review of the relationship between heart failure and cognitive impairment

ESC Heart Failure, Volume 12, Issue 2, Page 1119-1131, April 2025.
Abstract Large clinical data underscore that heart failure is independently associated to an increased risk of negative cognitive outcome and dementia. Emerging evidence suggests that cerebral hypoperfusion, stemming from reduced cardiac output and vascular pathology, may contribute to the largely overlapping vascular dementia and Alzheimer's disease ...

Cordycepin mediates neuroprotection against apoptosis via ERK/CREB signaling activation in Aβ1–42‐induced neuronal cell models

Ibrain, Volume 11, Issue 1, Page 84-97, Spring 2025.
This study demonstrates cordycepin's neuroprotective effects against Aβ1–42‐induced apoptosis in neuronal cells, mediated through the activation of the extracellular signal‐regulated kinase/cyclic AMP‐responsive element‐binding protein (ERK/CREB) signaling pathway.

Cognition in menopausal women

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Cognitive health in postmenopausal women is significantly affected by hormonal shifts, especially the drop in estrogen levels. This review explores the intricate relationship between menopause and cognitive functions across six domains: perception, attention, memory, language, executive functioning, and motor skills.

Tannic Acid Mitigates Monosodium Glutamate‐Induced Cortical Damage by Modulating Synaptic and Calcium‐Related Gene and Protein Expression

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neurotoxicity induced by excessive glutamatergic signaling is associated with synaptic dysfunction, calcium imbalance, and oxidative stress, which are key molecular events implicated in several neurodegenerative conditions. Monosodium glutamate (MSG), a common flavor enhancer, may exert neurotoxic effects, particularly on synaptic integrity ...
