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 ...

Blockade of the Interaction of Calcineurin with FOXO in Astrocytes Protects Against Amyloid-β-Induced Neuronal Death
(IOS Press, 2016-06-07)
Astrocytes actively participate in neuro-inflammatory processes associated to Alzheimer’s disease (AD), and other brain pathologies. We recently showed that an astrocyte-specific intracellular signaling pathway involving ...

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 ...

Use of human pluripotent stem cell-derived cells for neurodegenerative disease modeling and drug screening platform
(Future Science Group, 2019)
Most neurodegenerative diseases are characterized by a complex and mostly still unresolved pathology. This fact, together with the lack of reliable disease models, has precluded the development of effective therapies ...

Human Pluripotent Stem Cell-Derived Neural Cellsas a Relevant Platform for Drug Screening inAlzheimer’s Disease
(MDPI, 2020)
Extracellular amyloid-beta deposition and intraneuronal Tau-laden neurofibrillary tanglesare prime features of Alzheimer’s disease (AD). The pathology of AD is very complex and still notfully understood, since different ...

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 ...

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 ...
Artículo
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 ...
