Plaque-Associated Oligomeric Amyloid-Beta Drives Early Synaptotoxicity in APP/PS1 Mice Hippocampus: Ultrastructural Pathology Analysis
(Frontiers Media, 2021)
Alzheimer’s disease (AD) is a devastating neurodegenerative disorder characterized by initial memory impairments that progress to dementia. In this sense, synaptic dysfunction and loss have been established as the pathological ...

Regional difference in inflammatory response to LPS-injection in the brain: Role of microglia cell density
(Elsevier, 2011)
To elucidate whether density of cells could contribute to the extent of microglial activation, we performed in vitro assays using three different densities of N13 microglia stimulated with LPS. Our results showed that ...

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 ...

Abnormal accumulation of autophagic vesicles correlates with axonal and synaptic pathology in young Alzheimer’s mice hippocampus
(Springer, 2012)
Dystrophic neurites associated with amyloid plaques precede neuronal death and manifest early in Alzheimer’s disease (AD). In this work we have characterized the plaque-associated neuritic pathology in the hippocampus ...

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 ...

Galectin-3 is elevated in CSF and is associated with A beta deposits and tau aggregates in brain tissue in Alzheimer's disease
(Springer, 2022)
Galectin-3 (Gal-3) is a beta-galactosidase binding protein involved in microglial activation in the central nervous system (CNS). We previously demonstrated the crucial deleterious role of Gal-3 in microglial activation ...

Distinct disease-sensitive GABAergic neurons in the perirhinal cortex of Alzheimer's mice and patients
(Wiley Open Access, 2019)
Neuronal loss is the best neuropathological substrate that correlates with cortical atrophy and dementia in Alzheimer’s disease (AD). Defective GABAergic neuronal functions may lead to cortical network hyperactivity and ...

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, ...

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 ...

Aβ oligomers trigger necroptosis-mediated neurodegeneration via microglia activation in Alzheimer’s disease
(BMC, 2022)
Alzheimer’s disease (AD) is a major adult-onset neurodegenerative condition with no available treatment. Compelling reports point amyloid-β (Aβ) as the main etiologic agent that triggers AD. Although there is extensive ...
