Pio del Rio Hortega and the discovery of the oligodendrocytes
(Frontiers Research Foundation, 2015-07-07)
Rio del Rio Hortega (1882-1945) discovered microglia and oligodendrocytes (OLGs), and after Ramon y Cajal, was the most prominent figure of the Spanish school of neurology. He began his scientific career with Nicolas ...
Interaction between the 5-HT system and the basal ganglia: functional implication and therapeutic perspective in Parkinson's disease
(Frontiers Research Foundation, 2014-03-17)
The neurotransmitter serotonin (5-HT) has a multifaceted function in the modulation of information processing through the activation of multiple receptor families, including G-protein-coupled receptor subtypes (5-HT1, ...
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 ...
Behavioral, neurochemical and morphological changes induced by the overexpression of munc18-1a in brain of mice: relevance to schizophrenia
(Nature Publishing Group, 2013-01)
Overexpression of the mammalian homolog of the unc-18 gene (munc18-1) has been described in the brain of subjects with schizophrenia. Munc18-1 protein is involved in membrane fusion processes, exocytosis and neurotransmitter ...
Increased expression of cystine/glutamate antiporter in multiple sclerosis
(BioMed Central, 2011-06-03)
Background: Glutamate excitotoxicity contributes to oligodendrocyte and tissue damage in multiple sclerosis (MS). Intriguingly, glutamate level in plasma and cerebrospinal fluid of MS patients is elevated, a feature which ...
Neurotransmitter signaling in the pathophysiology of microglia
(Frontiers Research Foundation, 2013)
Microglial cells are the resident immune cells of the central nervous system. In the resting state, microglia are highly dynamic and control the environment by rapidly extending and retracting motile processes. Microglia ...
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 ...
NMDA modulates oligodendrocyte differentiation of subventricular zone cells through PKC activation
(Frontiers Research Foundation, 2013-12-18)
Multipotent cells from the juvenile subventricular zone (SVZ) possess the ability to differentiate into new neural cells. Depending on local signals, SVZ can generate new neurons, astrocytes, or oligodendrocytes. We ...
GABA release by hippocampal astrocytes
(Frontiers Res Found, 2012-08-17)
Astrocytes can directly influence neuronal activity through the release of various transmitters acting on membrane receptors expressed by neurons. However, in contrast to glutamate and ATP for instance, the release of GABA ...
