Calcium signalling in oligodendrocytes [PDF]
Neurophysiology, 1995 Generation of calcium signal in mammalian oligodendrocytes is a result of two different mechanisms, namely: (i) transmembrane calcium influx via voltage-operated calcium channels, and (ii) calcium release from IP3-sensitive internal calcium stores.

Trends in Neurosciences, 1996
In the adult vertebrate CNS, oligodendrocytes are ubiquitously distributed throughout white matter. By contrast, in the embryonic CNS, recent studies suggest that oligodendrocyte precursors arise in a discrete ventral location. Thus, local ventral environmental signals that contribute to the overall patterning of the CNS are likely to influence the ...

Regulation of oligodendrocyte development
Molecular Neurobiology, 1998Oligodendrocytes are the cells responsible for the formation of myelin in the central nervous system. Recent studies demonstrated that cells of the oligodendrocyte lineage initially arise in distinct regions of the ventricular zone during early development.

Oligodendrocytes, GRPs and MNOPs
Trends in Neurosciences, 2003What about earlier stages? At developmental stages earlier than E16, expression of Olig1 and Olig2 is limited to a large ventral domain of the proliferating ventricular zone that is known to generate both motoneurons and oligodendrocytes. If Olig2 expression is confined to an oligodendrocyte–motoneuron precursor, then its expression should not be seen ...

The oligodendrocytic junctional complex
Cell and Tissue Research, 1978The junctional complex of oligodendrocytes was studied by means of different electron microscopical techniques. This complex is composed of the following junctional membrane formations: 1) tight junctional domains in the oligodendrocytic membrane near the some of the cells, 2) fasciae occludentes or focal tight junctions on the outer oligodendrocytic ...

Expression of plasmolipin in oligodendrocytes
Journal of Neuroscience Research, 1991AbstractPlasmolipin is a plasma membrane proteolipid which has recently been described as a component of myelin (Cochary et al.: Journal of Neurochemistry 55:602–610, 1990). The present study reports the expression and localization of plasmolipin in primary glial cultures and secondary oligooendrocyte cultures.

Tight junctions of oligodendrocytes
Cell and Tissue Research, 1977Freeze-fracture replicas of the rat corpus callosum revealed prominent junctional strands in fractured cell membranes of the somata of oligodendrocytes. The junctional strands were characterized by an elaborate system of straight or slightly undulating rows of linear aggregates of particles or ridges in the P face and furrows in the E face.

Telomerase and oligodendrocyte differentiation
Journal of Neurobiology, 2001AbstractMyelin in the mammalian central nervous system (CNS) is produced by oligodendrocytes, most of which arise from oligodendrocyte precursor cells (OPCs) during late embryonic and early postnatal development. Both external and internal cues have been implicated in regulating OPC exit from the cell cycle and differentiation into oligodendrocytes. In

Oligodendrocyte degeneration in AD
Neurobiology of Aging, 2004Most would agree with a description of Alzheimer’s disease (AD) primarily as a degeneration of the cerebral cortex. As a result, much laboratory research in the past decade has focused on the cell death mechanisms of neurons. However, it may be time broaden the focus of AD research to include dysfunction of the tracts that connect cortical areas.

The human oligodendrocyte proteome
PROTEOMICS, 2013Myelination of the CNS is performed by oligodendrocytes (OLs), which have been implicated in brain disorders, such as multiple sclerosis and schizophrenia. We have used the human oligodendroglial cell line MO3.13 to establish an OL reference proteome database.
