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, ...

Neocortical tissue recovery in severe congenital obstructive hydrocephalus after intraventricular administration of bone marrow-derived mesenchymal stem cells
(BMC, 2020)
BACKGROUND: In obstructive congenital hydrocephalus, cerebrospinal fluid accumulation is associated with high intracranial pressure and the presence of periventricular edema, ischemia/hypoxia, damage of the white matter, ...

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 ...

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 ...

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 ...

Galectin‑3, a novel endogenous TREM2 ligand, detrimentally regulates infammatory response in Alzheimer’s disease
(Springer, 2019)
Alzheimer’s disease (AD) is a progressive neurodegenerative disease in which the formation of extracellular aggregates of amyloid beta (Aβ) peptide, fibrillary tangles of intraneuronal tau and microglial activation are ...
Artículo
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 ...
Artículo
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 ...

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, ...
