Amyloid β1-42 (Aβ1-42) Induces the CDK2-Mediated Phosphorylation of Tau through the Activation of the mTORC1 Signaling Pathway While Promoting Neuronal Cell Death

Frontiers in Molecular Neuroscience, 2017
Alzheimer’s disease (AD) is a neurodegenerative disorder, characterized by cognitive impairment and memory loss. Amyloid β1-42 (Aβ) and hyper-phosphorylation of microtubule-associated protein tau have been considered as major histological features in AD.

Heparan sulfate and glycomimetics: Advances in synthesis and biological applications for post‐stroke neurorepair

Neuroprotection, EarlyView.
ECM, extracellular matrix; BDNF, brain‐derived neuroptrophic factor; FGF, fibroblast growth factor; VEGF, vascular endothelial growth factor. Abstract Heparan sulfate, a structurally diverse glycosaminoglycan that is abundant in the central nervous system (CNS), orchestrates essential processes fundamental to neural plasticity, neurorepair, and ...

Data‐driven thresholds for standardized classification of severe Alzheimer's disease neuropathology using digital neuropathology

Brain Pathology, EarlyView.
We generated digital pathologic algorithms (AI‐based modules that can be freely shared) to: optimize the sampling (ROI) for diagnosis of ADNC‐related tau pathology; compare/transition between Aperio and HALO platforms; and rationalize severe Braak NFT staging, so that all Braak‐VI cases had dementia, and all Braak‐V cases had MCI or dementia.

Distinctly altered TRPC3 and TRPC6 expression patterns in human Alzheimer's disease cortex and hippocampus

Brain Pathology, EarlyView.
Divergent remodeling of TRPC channels occurs in Alzheimer's disease, with TRPC3 increased in neurons and reactive astrocytes and TRPC6 reduced in pyramidal neurons. These alterations may contribute to calcium dysregulation, neuroinflammation, and synaptic dysfunction during AD progression.

Investigation of the pharmacological activity of the tetrapeptide HAEЕ, zinc, and human serum albumin in a transgenic mouse model with tau protein overexpression (P301S)

Research Results in Pharmacology
Introduction: Neurodegenerative diseases affecting neurons represent a wide spectrum of pathological conditions. To slow the accumulation of pathological tau protein, therapeutic interventions such as a pharmaceutical composition consisting of the ...

Tauopathies as clinicopathological entities [PDF]

Parkinsonism & Related Disorders, 2016
Tauopathies are a class of neurodegenerative disorders characterized by neuronal and/or glial inclusions composed of the microtubule-binding protein, tau. Several lines of evidence suggest tau aggregation is central to the neurodegenerative process in tauopathies.

Clinicopathological and molecular heterogeneity of amyloid‐β in unnatural deaths under 70 years: A forensic autopsy–based study

Brain Pathology, EarlyView.
This study investigates amyloid‐beta (Aβ) pathology in a forensic autopsy cohort of relatively young individuals (40–69 years). Using detailed immunohistochemical analyses of multiple Aβ species, we demonstrate marked regional and molecular heterogeneity, particularly within the striatum.

Artificial intelligence–based 3D segmentation of tangle‐associated TDP‐43 in neurodegeneration

Brain Pathology, EarlyView.
Multiplex immunostaining of anti‐phosphorylated TDP‐43, tau (AT8, pS396, TauC3, MN423, GT38), and Thioflavin S combined with AI‐based object recognition, reconstruction, and TAT maturation analysis pipeline in limbic regions revealed that distinct aggregation and tangle maturation patterns underscored region‐specific dynamics in the neurodegenerative ...

Heritability in frontotemporal tauopathies

Alzheimer's & Dementia: Diagnosis, Assessment & Disease Monitoring, 2019
AbstractIntroductionExploring the degree of heritability in a large cohort of frontotemporal lobar degeneration with tau‐immunopositive inclusions (FTLD‐tau) and determining if different FTLD‐tau subtypes are associated with stronger heritability will provide important insight into disease pathogenesis.MethodsUsing modified Goldman pedigree ...

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...
