Hippocampal Changes in Down’s Syndrome

open access: yesPediatric Neurology Briefs, 1995
Semiquantitative scales and quantitative computerized image analyses were used to determine the neurofibrillary tangle formation and AB amyloid deposition in the hippocampal formation and inferior temporal gyrus in 36 Down’s syndrome cases, aged 4 to 73 ...

The Wnt/β-catenin signaling pathway affects the distribution of cytoskeletal proteins in Aβ treated PC12 cells [PDF]

open access: yesJournal of Integrative Neuroscience, 2019
Alzheimer’s disease is pathologically characterized by the presence of senile plaques and neurofibrillary tangles in the central nervous system. Amyloid β-protein is toxic to neurons and induces phosphorylation of Tau protein, which accumulates in paired

A case of diffuse neurofibrillary tangles with calcification [PDF]

open access: yesPsychiatry and Clinical Neurosciences, 2002
Abstract We report a 79‐year‐old female with atypical senile dementia with Fahr‐type calcification. The patient started to show memory disturbance at the age of 75 years, followed by visual hallucination, stereotypy, personality changes such as irritability, aggression and disinhibition.

Pre-assembled tau filaments phosphorylated by GSK-3b form large tangle-like structures

open access: yesNeurobiology of Disease, 2008
Hyperphosphorylated tau protein is a major component of neurofibrillary tangles, a prominent intracellular hallmark of Alzheimer's disease. Both hyperphosphorylated tau and neurofibrillary tangles have been shown to correlate with dementia in Alzheimer's

Expression of CD74 is increased in neurofibrillary tangles in Alzheimer's disease

open access: yesMolecular Neurodegeneration, 2008
Alzheimer disease (AD) is a chronic neurodegenerative disease that is characterized by progressive memory loss. Pathological markers of AD include neurofibrillary tangles, accumulation of amyloid-β plaques, neuronal loss, and inflammation.

Amyloid-beta aggregation implicates multiple pathways in Alzheimer’s disease: Understanding the mechanisms

open access: yesFrontiers in Neuroscience, 2023
Alzheimer’s disease (AD) is a progressive neurodegenerative condition characterized by tau pathology and accumulations of neurofibrillary tangles (NFTs) along with amyloid-beta (Aβ).

Brain ethanolamine phospholipids, neuropathology and cognition: A comparative post-mortem analysis of structurally specific plasmalogen and phosphatidyl species

open access: yesFrontiers in Cell and Developmental Biology, 2022
Reduced cognition in the elderly is associated with low levels of plasmalogens and high levels of lipid rafts, amyloid plaques, and neurofibrillary tangles in the temporal cortex.

Synaptic tau: A pathological or physiological phenomenon?

open access: yesActa Neuropathologica Communications, 2021
In this review, we discuss the synaptic aspects of Tau pathology occurring during Alzheimer’s disease (AD) and how this may relate to memory impairment, a major hallmark of AD.

Tau-Mediated Disruption of the Spliceosome Triggers Cryptic RNA Splicing and Neurodegeneration in Alzheimer’s Disease

open access: yesCell Reports, 2019
Summary: In Alzheimer’s disease (AD), spliceosomal proteins with critical roles in RNA processing aberrantly aggregate and mislocalize to Tau neurofibrillary tangles.

Mild heat stress induces hormetic effects in protecting the primary culture of mouse prefrontal cerebrocortical neurons from neuropathological alterations

open access: yesIBRO Reports, 2018
Hormesis is a dose response phenomenon of cells and organisms to various types of stressors. Mild stress stimulates prosurvival pathways and makes the cells adaptive to stressful conditions.
