Neuroglia cells. Coloured scanning electron micrograph (SEM) of cultured neuroglia cells (blue). These cells are found in nervous tissue and support nerve fibres both structurally and metabolically. They have numerous long processes (green) which attach them to other neuroglia cells (as seen here), and also to nerve cells. Neuroglia cells make up around half the mass of the central nervous system. Magnification: x1500 at 6x7cm size. - Stock Image P360/0222
Two classes of glial cells are found in the embryonic Drosophila CNS, midline glial cells and lateral glial cells. Midline glial development is triggered by EGF-receptor signalling, whereas lateral glial development is controlled by the gcm gene. Subsequent glial cell differentiation depends partly on the pointed gene. Here we describe a novel component required for all CNS glia development. The tramtrack gene encodes two zinc-finger proteins, one of which, ttkp69, is expressed in all non-neuronal CNS cells. We show that ttkp69 is downstream of gcm and can repress neuronal differentiation. Double mutant analysis and coexpression experiments indicate that glial cell differentiation may depend on a dual process, requiring the activation of glial differentiation by pointed and the concomitant repression of neuronal development by tramtrack.. ...
TY - JOUR. T1 - Role of the postnatal radial glial scaffold for the development of the dentate gyrus as revealed by reelin signaling mutant mice. AU - Brunne, Bianka. AU - Franco, Santos. AU - Bouché, Elisabeth. AU - Herz, Joachim. AU - Howell, Brian W.. AU - Pahle, Jasmine. AU - Müller, Ulrich. AU - May, Petra. AU - Frotscher, Michael. AU - Bock, Hans H.. PY - 2013/8/1. Y1 - 2013/8/1. N2 - During dentate gyrus development, the early embryonic radial glial scaffold is replaced by a secondary glial scaffold around birth. In contrast to neocortical and early dentate gyrus radial glial cells, these postnatal glial cells are severely altered with regard to position and morphology in reeler mice lacking the secreted protein Reelin. In this study, we focus on the functional impact of these defects. Most radial glial cells throughout the nervous system serve as scaffolds for migrating neurons and precursor cells for both neurogenesis and gliogenesis. Precursor cell function has been demonstrated for ...
One of the numerous functions of glial cells in Drosophila is the ensheathment of neurons to isolate them from the potassium-rich haemolymph, thereby establishing the blood-brain barrier. Peripheral nerves of flies are surrounded by three distinct glial cell types. Although all embryonic peripheral glia (ePG) have been identified on a single-cell level, their contribution to the three glial sheaths is not known. We used the Flybow system to label and identify each individual ePG in the living embryo and followed them into third instar larva. We demonstrate that all ePG persist until the end of larval development and some even to adulthood. We uncover the origin of all three glial sheaths and describe the larval differentiation of each peripheral glial cell in detail. Interestingly, just one ePG (ePG2) exhibits mitotic activity during larval stages, giving rise to up to 30 glial cells along a single peripheral nerve tract forming the outermost perineurial layer. The unique mitotic ability of ePG2 ...

Neuroglial cells constitute a separate class of cells in the nervous system; they have been studied intensively since their original description by Virchow in 1846. As a rule anatomists find no difficulty in recognizing them by their staining properties, their shape and configuration as well as by their characteristic location between and around neurons. Electron microscopy has in recent years added much important subcellular detail and has shown how intermingled neurons and glial cells are, being separated from each other by narrow clefts 100 to 200 Å wide (figures 1 A, B and 5, plates 1, 2 and 4). These studies have not changed the well-established grouping of mammalian glial cells into two main classes, the oligodendrocytes and the astrocytes. It is customary to state that glial cells outnumber neurons by 10 to 1 in the vertebrate nervous sytem. They are, however, smaller and according to some rough estimates they make up as much as 50% of the volume of mammalian brains. That glial cells ...
Tanycytes are special ependymal cells found in the third ventricle of the brain, and on the floor of the fourth ventricle and have processes extending deep into the hypothalamus. It is possible that their function is to transfer chemical signals from the cerebrospinal fluid (CSF) to the central nervous system (CNS). The term tanycyte comes from the Greek word tanus which means elongated. Tanycytes share some features with radial glia cells and astrocytes. Their form and location have led some authors to regard them as radial glia cells that remain in the hypothalamus throughout life. This has led some to believe that these cells share the same lineage. Even so, tanycytes also display certain characteristics that distinguish them from radial glia cells. Tanycytes in rats begin to develop in the last two days of gestation and continue on until they reach their full differentiation in the first month of life. Radial glia cells on the other hand, are a key component of the embryonic brain. Tanycytes ...
The objective of this study was to begin to examine the cellular and biophysical effects on human retinal glial cells of basic fibroblast growth factor (bFGF), which is endogenous to the retina and likely to play a role in retinal pathobiology. Experiments were performed on cultured glial cells derived from the adult postmortem retina. A proliferative response to bFGF established a sensitivity of the retinal glia to this growth factor. The possibility that bFGF alters calcium currents was assessed using the whole-cell recording configuration of the patch-clamp technique to analyze inward currents carried by barium. Two types of voltage-gated calcium channels could be expressed by the glial cells. One, similar to the T-type current described in various kinds of cells, had a low threshold of activation, a transient response, and an insensitivity to the dihydropyridine nifedipine. The other type of inward current, which closely resembles the L-type calcium current found in other cells, had a high ...
This chapter focuses on the role of neurogenic astroglial cells in the development of the central nervous system (CNS). Recent findings have elucidated a more complex role for astroglial cells in the development of CNS structures across many species. Mitotically active radial glial cells line the ventricular system throughout the developing CNS and have been shown to generate neocortical neurons in rodents. Precursor cells in the ventricular zone (VZ) can divide symmetrically or asymmetrically, and evidence indicates that both types of divisions coexist throughout the entire period of cortical neurogenesis. ...

Neuronal survival and functions require bidirectional communication between neurons and glia that involves a large variety of growth factors. Neurotrophic factors are operationally defined as proteins that regulate neuron survival and differentiation. They can be synthesized by nonneuronal target cells, neurons, and glial cells. This chapter focuses on neurotrophic factors secreted from macroglial cells, that is, astrocytes, oligodendrocytes, and Schwann cells, and their effects on neuronal differentiation and survival in the intact and lesioned brain and peripheral nervous system. ...
TY - JOUR. T1 - Calcium increases in retinal glial cells evoked by light-induced neuronal activity. AU - Newman, Eric A.. PY - 2005/6/8. Y1 - 2005/6/8. N2 - Electrical stimulation of neurons in brain slices evokes increases in cytoplasmic Ca2+ in neighboring astrocytes. The present study tests whether similar neuron-to-glial signaling occurs in the isolated rat retina in response to light stimulation. Results demonstrate that Müller cells, the principal retinal glial cells, generate transient increases in Ca2+ under constant illumination. A flickering light stimulus increases the occurrence of these Ca2+ transients. Antidromic activation of ganglion cell axons also increases the generation of Müller cell Ca 2+ transients. The increases in Ca2+ transients evoked by light and antidromic stimulation are blocked by the purinergic antagonist suramin and by TTX. The addition of adenosine greatly potentiates the response to light, with light ON evoking large Ca2+ increases in Müller cells. Suramin, ...
A study performed in November 2010 and published March 2011, was done by a team of scientists from the University of Rochester and University of Colorado School of Medicine. They did an experiment to attempt to repair trauma to the Central Nervous System of an adult rat by replacing the glial cells. When the glial cells were injected into the injury of the adult rats spinal cord, astrocytes were generated by exposing human glial precursor cells to bone morphogenetic protein (Bone morphogenetic protein is important because it is considered to create tissue architecture throughout the body). So, with the bone protein and human glial cells combined, they promoted significant recovery of conscious foot placement, axonal growth, and obvious increases in neuronal survival in the spinal cord laminae. On the other hand, human glial precursor cells and astrocytes generated from these cells by being in contact with ciliary neurotrophic factors, failed to promote neuronal survival and support of axonal ...

Glial cells are central components of all neurogenic niches in the embryonic as well as in the adult central nervous system. While neural stem cells (NSCs) themselves exhibit glial features the behavior of NSCs is also strongly influenced by niche glial cells. Recently, studies have begun to uncover a large variety of glial cell-extrinsic as well as intrinsic factors that play crucial roles in the control of NSCs and the regulation of the cellular output from the neurogenic niches. In this review, we focus on mechanisms underlying the formation of adult NSCs by embryonic radial glia cells, discuss the influence of niche glia cells on adult NSCs and examine how the neurogenic potential of glial cells is controlled ...

Figure 3 Astrocyte They regulate the external chemical environment of neurons by removing excess ions, the notable one being potassium, and recycling neurotransmitters released during synaptic transmission. The current theory suggests that astrocytes may be the predominant "building-blocks" of the blood-brain barrier. Astrocytes may regulate vasoconstriction and vasodilation by producing substances such as arachidonic acid, whose metabolites are vasoactive. Astrocytes signal each other using calcium. The gap junctions (also known as electrical synapses) between astrocytes allow the messenger molecule IP3 to diffuse from one astrocyte to another. IP3 activates calcium channels on cellular organelles, releasing calcium into the cytoplasm. This calcium may stimulate the production of more IP3. The net effect is a calcium wave that propagates from cell to cell. Extracellular release of ATP, and consequent activation of purinergic receptors on other astrocytes, may also mediate calcium waves in some ...
Müller glial cultures have made a significant contribution for understanding retinal pathophysiology, especially in the context of retinal degenerative diseases. Primary Müller glial cultures have several advantages, largely due to their phenotypic and functional similarity to Müller glia in vivo. There are, however, several disadvantages in using primary cultures, including limited availability, and inconsistency in experimental results, perhaps due to purity, heterogeneity across different batches, and phenotypic instability across multiple passages.14 The use of a stabilized cell line can overcome these drawbacks, although it is recommended that key results obtained from cell lines are further validated using primary cells and in vivo models. Various Müller glial cell lines, derived from rodents14-17 or humans18 have been reported. Although they all express Müller glial markers, each cell line has its own characteristics and is used to study different functions of Müller glia. For ...

For many years neurons have been considered the main act within the cerebral cortex, responsible for our thoughts, emotions, and movements. Of interest is the fact that neurons only account for about 10% of human brain cells. Glial cells that account for the other 90% of brain cells have typically been thought to carry a supportive role to the neurons.. An article in Forbes Magazine (July 13, 2009), however, suggests glial cells may be even more important than neurons for treating neurodegenerative diseases such as Alzheimers, Parkinsons, and stroke. Recent understanding of the brain now indicates glial cells with neurons play a critical role in brain development and brain function.. Medications on the market today do not work on glial cells. Ben Barnes, Chairman of the Neurobiology Department at Stanford University Medical School posits that one type of glial cells, the astrocytes, trigger the initial steps of destruction in brain diseases. As such, Dr. Barnes believes that by creating ...
Nature Neuroscience has a nice special focus on glia and disease. The featured reviews and perspective articles discuss multiple aspects of neuron-glia interactions and their role in disease. The reason why I am highlighting this collection here is that I have the feeling that this field could potentially be a nice playground for systems biology.. For example, Rossi and colleagues (2007) review the various metabolic processes affected during brain ischemia. Several of the examples discussed illustrate very well how the extent of brain damage is determined by the concurrent dynamics of both harmful and protective processes engaging complex interactions between neurons and astrocytes. A critical determinant for ischemic damage is the catastrophic loss of ATP levels caused by deficient glucose and oxygen delivery. Astrocytes have glycogen stores that can normally be converted to lactate which is exported to neurons to provide energy during phases of high activity. In absence of oxygen however, ...
TY - JOUR. T1 - Neuron-glia synapses in the brain. AU - Bergles, Dwight E. AU - Jabs, Ronald. AU - Steinhäuser, Christian. PY - 2010/5. Y1 - 2010/5. N2 - The ability to investigate the electrophysiological properties of individual cells in acute brain tissue led to the discovery that many glial cells have the capacity to respond rapidly to neuronal activity. In particular, a distinct class of neuroglial cells known as NG2 cells, which exhibit many of the properties that have been described for glial subtypes such as complex cells, polydendrocytes, synantocytes and GluR cells, express ionotropic receptors for glutamate and GABA. In both gray and white matter, NG2 cells form direct synaptic junctions with axons, which enable transient activation of these receptors. Electrophysiological analyses have shown that these neuron-glia synapses exhibit all the hallmarks of classical neuron-neuron synapses, including rapid activation, quantized responses, facilitation and depression, and presynaptic ...
Neuroglial or glial cells, make up one of the two major cellular components of nervous tissue (the other being neurons). Nervous tissue is composed of almost 10 times as many glial cells as neurons. They primarily provide structural and metabolic support for neurons, some aid in communication between neurons and assist in neurological development, while others respond to damage and pathogens. Glial cells are divided into two major classes of cell types: microglia and macroglia. The microglia are primarily phagocytes, they are mobilized by minor pathological changes and can eliminate invading microorganisms, promote tissue repair, and remove debris. Macroglia are separated into four classes: ogliodendrocytes, Schawnn cells, astrocytes, and ependymal cells. Schwann cells and ogliodendrocytes form the myelin sheath around neuron axons. This sheath insulates the electrical impulse that travels down the axon, but also increases the speed of the electrical propagation by keeping unmylinated spaces ...
The goal of my research is to understand how inflammation in the nervous system (neuroinflammation) leads to long-term changes in neural circuitry. Within this context, we focus on the regulation of neural networks by glial cells, with particular interests in clarifying the role of glial cells in nervous system physiology and elucidating how glial changes during neuroinflammation contribute to neurodegenerative diseases. We are addressing this issue by exploring how neuron-glia interactions in the enteric nervous system (ENS) regulate gut physiology and pathophysiology. The ENS is particularly well suited for this kind of work because neuron-glia interactions in the gut can be studied in situ using preparations with intact synaptic pathways or in vivo in animal models. Further, the synaptic pathways of enteric neural networks are well defined and the output of ENS activity can be clearly assessed with functional assays. Our experiments will allow us to understand the fundamental rules that ...

Five novel cDNA clones were isolated and identified from a differentiated glial subtractive library. They were shown to be specific to the nervous system by Northern blotting analysis. In situ hybridisation (ISH) studies were carried out on cultured glial cells to determine if any of the clones were expressed by specific glial cell types. Oligodendrocytes were identified by the monoclonal antibody O4 and astrocytes were identified with an anti-GFAP monoclonal antibody. Clone OL0755, one of the novel brain specific clones identified, was chosen for further investigation. Two cDNA clones, believed to be full length, were obtained by hybridisation screening of a rat cDNA library. Clone OL0755-A is 2.7 kb and encodes a protein of approximately 60 kD. Clone OL0755-B is 2 kb in size and encodes a protein of approximately 50 kD. Sequence analysis showed these clones to be two alternatively spliced forms of a common gene. An antibody (Ab755) raised against a 23 amino acid N-terminus peptide common to ...

Our research goal is to identify the receptors and intracellular signaling pathways mediating the effects of extracellular Tfam as well as microparticles originating from different types of brain cells under different conditions. This information is critical not only for our understanding of the mechanisms governing homeostasis of the central nervous system, but it could also lead to identification of novel molecular targets that could be used to manipulate the functional responses of glial cells. An increasing body of evidence indicates that glial cell activation is part of a series of physiological events, but it can also contribute to various central nervous system pathologies, such as stroke, trauma and neurodegenerative disorders including Alzheimers disease. Therefore, an additional focus of our laboratory is identification of novel drugs and natural compounds that could be used to modify glial functions. In the past, we have performed studies with bioactive compounds extracted from ...

The brain is made up of discrete cellular elements. There are two types of cell which make up the brain - neurons and glia. There are between 1011 and 1012 nerve cells in the human brain and each cell Can have up to 103, or 104 connections to other cells. It is these connections and the interactions of the nerve cells which enable learning, remembering, abstraction and much more. The function of glial cells (neuroglia) is not fully understood, but is thought to be a supporting function to the neuron. They do not appear to be involved directly in information processing. They are more numerous than neurons and fill up the space between them, providing a structural framework for neurons, especially during brain development. The neuron has been studied in far more depth and most of the rest of this paper will consider these cells and how they are combined into the nervous system ...

The human ApoE exists in three isoforms of which the ApoE4 isoform is associated with an increased risk of developing Alzheimers disease (AD). Furthermore, epidemiological studies revealed that patients with hypercholesterolemia that were treated with cholesterol lowering drugs also had a reduced risk of developing AD. This implicates ...
Netrins are laminin-related proteins that guide circumferential migrations on the ectoderm. To understand how netrin cues direct cell movements, the expression of nematode netrin UNC-6 has been examined at all stages from embryo to adult. UNC-6 is expressed in 12 types of neuroglia and neurons, creating a hierarchy of netrin cues in the developing nervous system. Multiple netrin cues, each with a characteristic role, guide cells and axons during development. The biological activities of netrins are mediated through distinct protein domains. Subtle mutations in domain VI can produce selective defects in both direction- and tissue-specific guidance. EGF-like module V-2 is essential for dorsal guidance activity; this module is important for interactions between UNC-6 and the dorsal guidance receptor UNC-5 (Wadsworth, 1996). The netrin guidance cue, UNC-6, and the netrin receptors, UNC-5 and UNC-40 (Drosophila homolog: Frazzled), guide SDQR cell and axon migrations in C. elegans. This neuron is part ...

David: Thanks for your comments on aging. Regarding telomeres and non-dividing cells such as neurons and muscle cells (unless we include the exceptions in the olfactory bulb and satellite cells respectively), please remember that none of these cells function in isolation. In the case of the nervous system, for example, only 10% of the cells are neural, whereas 90% are glial. Glial cells (especially microglia, which are implicated in the early inflammation which is part of the poorly understood etiology of Alzheimers dementia) do divide. Their telomeres may therefore play a prominent role in this common form of dementia. The (unproven) model would go something like this. The glia divide, their telomeres shorten, their gene expression alters during the gradual loss of the last few thousand DNA bases, glial function alters and they no longer provide neurotropic factors in the abundance (or pattern) sufficient for normal neuron function, and some neurons show typical changes consistant with ...

We have initiated studies to identify membrane polypeptides of radial glial cells that contribute to the selective cell-cell recognition and migration events in developing brain. Of several polyclonal antisera evaluated, one (D4), developed against formaldehyde fixed type 1 cerebellar glial cells, immunolabels the free surface of cortical and cerebellar astroglial and radial glial cells in a patchy pattern. In dissociated glial-neuronal cell cocultures, microdomains of immunoreactivity are detected at the site where the somal region of cells with the morphology of migrating neurons is in contact with an elongated glial cell fiber. Microdomains are absent from oligodendrocytes, process-bearing astrocytes, and neurons. The surface microdomains do not colocalize with components that compose focal adhesion plaques--integrin subunits, vinculin, or actin--and their integrity appears to require an intact microtubule rather than actin cytoskeleton. Furthermore, microdomain structure is maintained in the ...

Trauma to either the central or peripheral nervous system often leads to significant loss of function and disability in patients. This high rate of long-term disability is due to the overall limited regenerative potential of nervous tissue, even though the peripheral nervous system (PNS) has more regenerative potential than the central nervous system (CNS). The supporting glial cells in the periphery, Schwann cells, are part of the reason for the improved recovery observed in the PNS. In the CNS, the glial populations, astrocytes and oligodendrocytes, do not have as much potential to promote regeneration and are at times inhibitory to neuronal growth ...
