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 ...
1-42 beta-Amyloid peptide requires PDK1/nPKC/Rac 1 pathway to induce neuronal death
(Nature Publishing Group, 2013-01)
1-42 beta-Amyloid (A beta(1-42)) peptide is a key molecule involved in the development of Alzheimer's disease. Some of its effects are manifested at the neuronal morphological level. These morphological changes involve ...
Oligodendrocyte differentiation from adult multipotent stem cells is modulated by glutamate
(Nature Publishing Group, 2012-02)
We used multipotent stem cells (MSCs) derived from the young rat subventricular zone (SVZ) to study the effects of glutamate in oligodendrocyte maturation. Glutamate stimulated oligodendrocyte differentiation from SVZ-derived ...
Contribution of Neurons and Glial Cells to Complement-Mediated Synapse Removal during Development, Aging and in Alzheimer’s Disease
(Hindawi, 2018)
Synapse loss is an early manifestation of pathology in Alzheimer's disease (AD) and is currently the best correlate to cognitive decline. Microglial cells are involved in synapse pruning during development via the complement ...
