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 ...

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, ...

Efectos de la acumulación del péptido Beta amiloide en tejido cerebral de ratones PS1xAPP modelos de la Enfermedad de Alzheimer
(2016-01-15)
Esta enfermedad se ha convertido en el tercer problema de salud más grave en los países desarrollados (detrás de los accidentes cardiovasculares y el cáncer). Existen alrededor de 800.000 enfermos diagnosticados en España ...

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 ...

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 ...

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 ...

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 ...
