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 ... -
ATP Antagonizes Thrombin-Induced Signal Transduction through 12(S)-HETE and cAMP
(Public Library of Science, 2013)In this study we have investigated the role of extracellular ATP on thrombin induced-platelet aggregation (TIPA) in washed human platelets. ATP inhibited TIPA in a dose-dependent manner and this inhibition was abolished ... -
Ca2+-dependent endoplasmic reticulum stress correlates with astrogliosis in oligomeric amyloid β-treated astrocytes and in a model of Alzheimer's disease
(2013)Neurotoxic effects of amyloid β peptides are mediated through deregulation of intracellular Ca2+ homeostasis and signaling, but relatively little is known about amyloid β modulation of Ca2+ homeostasis and its pathological ... -
Plasma brain-derived neurotrophic factor levels, learning capacity and cognition in patients with first episode psychosis
(BioMed Central, 2013)Background: Cognitive impairments are seen in first psychotic episode (FEP) patients. The neurobiological underpinnings that might underlie these changes remain unknown. The aim of this study is to investigate whether Brain ... -
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 ... -
Combined Fluorescent-Chromogenic In Situ Hybridization for Identification and Laser Microdissection of Interphase Chromosomes
(Public Library of Science, 2013)Chromosome territories constitute the most conspicuous feature of nuclear architecture, and they exhibit non-random distribution patterns in the interphase nucleus. We observed that in cell nuclei from humans with Down ... -
Janus-faced microglia: beneficial and detrimental consequences of microglial phagocytosis
(Frontiers Research Foundation, 2013-01)Microglia are the resident brain macrophages and they have been traditionally studied as orchestrators of the brain inflammatory response during infections and disease. In addition, microglia has a more benign, less explored ... -
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 ... -
Contribution of Pannexin1 to Experimental Autoimmune Encephalomyelitis
(Public Library of Science, 2013-06)Pannexin1 (Panx1) is a plasma membrane channel permeable to relatively large molecules, such as ATP. In the central nervous system (CNS) Panx1 is found in neurons and glia and in the immune system in macrophages and T-cells. ... -
Papel de las GTPasas de la familia rho en la señalización mediada por el receptor P2X7
(2013-09-24)El objetivo de este proyecto es estudiar la señalización del receptor P2X7 en respuesta a ATP en macrófagos J774A.1 y en células CHO K1. Para ello, se subclonó el gen que codifica para la proteína P2X7 en el vector PMT2 ... -
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 ... -
Differential Neuroprotective Effects of 5 '-Deoxy-5 '-Methylthioadenosine
(Public Library Science, 2014-03-05)Background: 5'-deoxy-5'-methylthioadenosine (MTA) is an endogenous compound produced through the metabolism of polyamines. The therapeutic potential of MTA has been assayed mainly in liver diseases and, more recently, in ... -
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 ... -
Never-resting microglia: physiological roles in the healthy brain and pathological implications
(Frontiers Research Foundation, 2014-08-15)Microglia are largely known as the major orchestrators of the brain inflammatory response. As such, they have been traditionally studied in various contexts of disease, where their activation has been assumed to induce a ... -
Purinergic signaling: a common pathway for neural and mesenchymal stem cell maintenance and differentiation
(null, 2015)Extracellular ATP, related nucleotides and adenosine are among the earliest signaling molecules, operating in virtually all tissues and cells. Through their specific receptors, namely purinergic P1 for nucleosides and P2 ... -
From the Cajal alumni Achucarro and Rio-Hortega to the rediscovery of never-resting microglia
(Frontiers Research Foundation, 2015-04-14)Under the guidance of Ramon y Cajal, a plethora of students flourished and began to apply his silver impregnation methods to study brain cells other than neurons: the neuroglia. In the first decades of the twentieth century, ... -
Subclinical Depressive Symptoms and Continued Cannabis Use: Predictors of Negative Outcomes in First Episode Psychosis
