In vivo modification of Abeta plaque toxicity as a novel neuroprotective lithium-mediated therapy for Alzheimer’s disease pathology
(BioMed Central, 2013)
Background: Alzheimer’s disease (AD) is characterized by the abnormal accumulation of extracellular beta-amyloid (Abeta) plaques, intracellular hyperphosphorylated tau, progressive synaptic alterations, axonal dystrophies, ...

Disruption of Amyloid Plaques Integrity Affects the Soluble Oligomers Content from Alzheimer Disease Brains
(Public Library of Science, 2014)
The implication of soluble Abeta in the Alzheimer's disease (AD) pathology is currently accepted. In fact, the content of soluble extracellular Abeta species, such as monomeric and/or oligomeric Abeta, seems to correlate ...

Dual roles of Aβ in proliferative processes in an amyloidogenic model of Alzheimer’s disease
(Nature Research (part of Springer Nature), 2017)
Alzheimer’s disease is a major neurodegenerative disorder that leads to severe cognitive deficits in the elderly population. Over the past two decades, multiple studies have focused on elucidating the causative factors ...

Should we open fire on microglia? Depletion models as tools to elucidate microglial role in health and alzheimer’s disease
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Microglia play a critical role in both homeostasis and disease, displaying a wide variety in terms of density, functional markers and transcriptomic profiles along the different brain regions as well as under injury or ...

Defective lysosomal proteolysis and axonal transport are early pathogenic events that worsen with age leading to increased APP metabolism and synaptic Abeta in transgenic APP/PS1 hippocampus
(2012)
Background: Axonal pathology might constitute one of the earliest manifestations of Alzheimer disease. Axonal dystrophies were observed in Alzheimer’s patients and transgenic models at early ages. These axonal dystrophies ...

Soluble phospho‑tau from Alzheimer’s disease hippocampus drives microglial degeneration
(Springer (part of Springer Nature): Springer Open Choice Hybrid Journals, 2016)
The role of microglial cells in the development and progression of Alzheimer’s disease (AD) has not been elucidated. Here, we demonstrated the existence of a weak microglial response in human AD hippocampus which is in ...

Hypoxia compromises the mitochondrial metabolism of Alzheimer’s disease microglia via HIF1
(Springer, 2021)
Genetic Alzheimer’s disease (AD) risk factors associate with reduced defensive amyloid β plaque-associated microglia (AβAM), but the contribution of modifiable AD risk factors to microglial dysfunction is unknown. In AD ...

Amyloid-β impairs the phagocytosis of dystrophic synapses by astrocytes in Alzheimer's disease
(Wiley, 2020)
Reactive astrocytes and dystrophic neurites, most aberrant presynaptic elements, are found surrounding amyloid-β plaques in Alzheimer's disease (AD). We have previously shown that reactive astrocytes enwrap, phagocytose, ...

Distinct Microglial Responses in Two Transgenic Murine Models of TAU Pathology
(Frontiers Media Research Foundation, 2018-11-14)
Microglial cells are crucial players in the pathological process of neurodegenerative diseases, such as Alzheimer’s disease (AD). Microglial response in AD has been principally studied in relation to amyloid-beta pathology ...

Phagocytic clearance of presynaptic dystrophies by reactive astrocytes in Alzheimer's disease
(Wiley, 2018)
Reactive astrogliosis, a complex process characterized by cell hypertrophy and upregulation ofcomponents of intermediate filaments, is a common feature in brains of Alzheimer’s patients. Reac-tive astrocytes are found in ...
