Glycosaminoglycans in human retinoblastoma cells: heparan sulfate, a modulator of the pigment epithelium-derived factor-receptor interactions
(BioMed Central, 2003-02-19)
BACKGROUND: Pigment epithelium-derived factor (PEDF) has binding affinity for cell-surface receptors in retinoblastoma cells and for glycosaminoglycans. We investigated the effects of glycosaminoglycans on PEDF-receptor ...
Astrocytes in Alzheimer’s Disease: Pathological Significance and Molecular Pathways
(MDPI, 2021-03-04)
Astrocytes perform a wide variety of essential functions defining normal operation of the nervous system and are active contributors to the pathogenesis of neurodegenerative disorders such as Alzheimer’s among others. ...
RNA Localization and Local Translation in Glia in Neurological and Neurodegenerative Diseases: Lessons from Neurons
(MDPI, 2021-03-12)
Cell polarity is crucial for almost every cell in our body to establish distinct structural and functional domains. Polarized cells have an asymmetrical morphology and therefore their proteins need to be asymmetrically ...
A Model of Ischemia-Induced Neuroblast Activation in the Adult Subventricular Zone
(Public Library of Science, 2009-04-23)
We have developed a rat brain organotypic culture model, in which tissue slices contain cortex-subventricular zone-striatum regions, to model neuroblast activity in response to in vitro ischemia. Neuroblast activation has ...
Amyloid β / PKC-dependent alterations in NMDA receptor composition are detected in early stages of Alzheimer´s disease
(SpringerNature, 2022-03-19)
[EN] Amyloid beta (Abeta)-mediated synapse dysfunction is an early event in Alzheimer's disease (AD) pathogenesis and previous studies suggest that NMDA receptor (NMDAR) dysregulation may contribute to these pathological ...
CGP37157, an inhibitor of the mitochondrial Na+/Ca2+ exchanger, protects neurons from excitotoxicity by blocking voltage-gated Ca2+ channels
(Nature Publishing Group, 2014-04)
Inhibition of the mitochondrial Na+/Ca2+ exchanger (NCLX) by CGP37157 is protective in models of neuronal injury that involve disruption of intracellular Ca2+ homeostasis. However, the Ca2+ signaling pathways and stores ...
Sephin1 Protects Neurons against Excitotoxicity Independently of the Integrated Stress Response
(MDPI, 2020-08-24)
Sephin1 is a derivative of guanabenz that inhibits the dephosphorylation of the eukaryotic initiation factor 2 alpha (eIF2α) and therefore may enhance the integrated stress response (ISR), an adaptive mechanism against ...
A beta oligomers promote oligodendrocyte differentiation and maturation via integrin beta 1 and Fyn kinase signaling
(Nature Publishing Group, 2019-06-06)
Alzheimer's disease (AD) is characterized by a progressive cognitive decline that correlates with the levels of amyloid beta-peptide (A beta) oligomers. Strong evidences connect changes of oligodendrocyte function with the ...
Recombinant Integrin β1 Signal Peptide Blocks Gliosis Induced by Aβ Oligomers
(MDPI, 2022-05-20)
Glial cells participate actively in the early cognitive decline in Alzheimer’s disease (AD) pathology. In fact, recent studies have found molecular and functional abnormalities in astrocytes and microglia in both animal ...
Intracellular Ca2+ release through ryanodine receptors contributes to AMPA receptor-mediated mitochondrial dysfunction and ER stress in oligodendrocytes
(Nature Publishing Group, 2010-07)
Overactivation of ionotropic glutamate receptors in oligodendrocytes induces cytosolic Ca2+ overload and excitotoxic death, a process that contributes to demyelination and multiple sclerosis. Excitotoxic insults cause ...
