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 ...

Monocyte-derived Cells Invade Brain Parenchyma and Amyloid Plaques in Human Alzheimer’s Disease Hippocampus
(Springer Nature, 2023)
Microglia are brain-resident myeloid cells and play a major role in the innate immune responses of the CNS and the pathogenesis of Alzheimer's disease (AD). However, the contribution of nonparenchymal or brain-infiltrated ...

Acute and Chronic Sustained Hypoxia Do Not Substantially Regulate Amyloid-β Peptide Generation In Vivo
(Public Library of Science, 2017)
Background Recent epidemiological evidence has linked hypoxia with the development of Alzheimer disease (AD). A number of in vitro and in vivo studies have reported that hypoxia can induce amyloid-β peptide accumulation ...

Inflammatory response in the hippocampus of PS1M146L/APP 751SL mouse model of Alzheimer's disease: Age-dependent switch in the microglial phenotype from alternative to classic
(Society for Neuroscience, 2008)
Although the microglial activation is concomitant to the Alzheimer's disease, its precise role (neuroprotection vs neurodegeneration) has not yet been resolved. Here, we show the existence of an age-dependent phenotypic ...

Enhancing microtubule stabilization rescues cognitive deficits and ameliorates pathological phenotype in an amyloidogenic Alzheimer’s disease model
(Nature Research, 2020)
In Alzheimer’s disease (AD), and other tauopathies, microtubule destabilization compromises axonal and synaptic integrity contributing to neurodegeneration. These diseases are characterized by the intracellular accumulation ...

Transgenic Mouse Models of Alzheimer’s Disease: An Integrative Analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Alzheimer’s disease (AD) constitutes the most prominent form of dementia among elderly individuals worldwide. Disease modeling using murine transgenic mice was first initiated thanks to the discovery of heritable mutations ...

Age-dependent accumulation of soluble amyloid β (Aβ) oligomers reverses the neuroprotective effect of soluble amyloid precursor protein-α (sAPPα) by modulating phosphatidylinositol 3-kinase (PI3K)/Akt-GSK- 3β pathway in Alzheimer mouse model
(American Society for Biochemistry and Molecular Biology Inc., 2011)
Neurotrophins, activating the PI3K/Akt signaling pathway, control neuronal survival and plasticity. Alterations in NGF, BDNF, IGF-1, or insulin signaling are implicated in the pathogenesis of Alzheimer disease. We have ...
