Microglia vary in appearance depending on developmental stage, functional state, and anatomical location; subtype terms include ramified, perivascular, ameboid, resting, and activated. Microglia clearly are capable of phagocytosis and play an important role in a wide spectrum of neuropathologies.

Myelinated nerve fibers are present in somatic and autonomic nerves.Antigens, CD47: A ubiquitously expressed membrane glycoprotein. It interacts with a variety of INTEGRINS and mediates responses to EXTRACELLULAR MATRIX PROTEINS.Brain: The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.Neural Cell Adhesion Molecule L1: A member of the immunoglobulin superfamily of neuronal cell adhesion molecules that is required for proper nervous system development. Neural cell adhesion molecule L1 consists of six Ig domains, five fibronectin domains, a transmembrane region and an intracellular domain. Two splicing variants are known: a neuronal form that contains a four-amino acid RSLE sequence in the cytoplasmic domain, and a non-neuronal form that lacks the RSLE sequence. Mutations in the L1 gene result in L1 disease. Neural cell adhesion molecule L1 is predominantly expressed during development in neurons and Schwann cells; involved in cell adhesion, neuronal migration, axonal growth and pathfinding, and myelination.Diffusion Tensor Imaging: The use of diffusion ANISOTROPY data from diffusion magnetic resonance imaging results to construct images based on the direction of the faster diffusing molecules.NorwayRhizoctonia: A mitosporic Ceratobasidiaceae fungal genus that is an important plant pathogen affecting potatoes and other plants.

Insulin-like growth factor-1 inhibits mature oligodendrocyte apoptosis during primary demyelination. (1/102)

Metabolic insult results in apoptosis and depletion of mature oligodendrocytes during demyelination. To examine the role of insulin-like growth factor-1 (IGF-1) during acute demyelination and remyelination in the adult CNS, we exposed transgenic mice that continuously express IGF-1 (IGF-1 tg) to cuprizone intoxication. Demyelination was observed within the corpus callosum in both wild-type and IGF-1 tg mice 3 weeks after exposure to cuprizone. Wild-type mice showed significant apoptotic mature oligodendrocytes and a dramatic loss of these cells within the lesion that resulted in near complete depletion and demyelination by week 5. In contrast, the demyelinated corpus callosum of the IGF-1 tg mice was near full recovery by week 5. This rapid recovery was apparently caused by survival of the mature oligodendrocyte population because apoptosis was negligible, and by week 4, the mature oligodendrocyte population was completely restored. Furthermore, despite demyelination in both wild-type and IGF-1 tg mice, oligodendrocyte progenitors accumulated only in the absence of mature oligodendrocytes and failed to accumulate if the mature oligodendrocytes remained as demonstrated in the IGF-1 tg mice. These results suggest that IGF-1 may be important in preventing the depletion of mature oligodendrocytes in vivo and thus facilitates an early recovery from demyelination.  (+info)

Absence of macrophage-inflammatory protein-1alpha delays central nervous system demyelination in the presence of an intact blood-brain barrier. (2/102)

Chemokines are small chemotactic cytokines that modulate leukocyte recruitment and activation during inflammation. Here, we describe the role of macrophage inflammatory protein-1alpha (MIP-1alpha) during cuprizone intoxication, a model where demyelination of the CNS features a large accumulation of microglia/macrophage without T cell involvement or blood-brain barrier disruption. RNase protection assays showed that mRNA for numerous chemokines were up-regulated during cuprizone treatment in wild-type, C57BL/6 mice. RANTES, inflammatory protein-10, and monocyte chemoattractant protein-1 showed greatest expression with initiation of insult at 1-2 wk of treatment, whereas MIP-1alpha and beta increased later at 4-5 wk, coincident with peak demyelination and cellular accumulation. The function of MIP-1alpha during demyelination was tested in vivo by exposing MIP-1alpha knockout mice (MIP-1alpha(-/-)) to cuprizone and comparing pathology to wild-type mice. Demyelination at 3.5 wk of treatment was significantly decreased in MIP-1alpha(-/-) mice ( approximately 36% reduction), a result confirmed by morphology at the electron microscopic level. The delay in demyelination was correlated to apparent decreases in microglia/macrophage and astrocyte accumulation and in TNF-alpha protein levels. It was possible that larger effects of the MIP-1alpha deficiency were being masked by other redundant chemokines. Indeed, RNase protection assays revealed increased expression of several chemokine transcripts in both untreated and cuprizone-treated MIP-1alpha(-/-) mice. Nonetheless, despite this possible compensation, our studies show the importance of MIP-1alpha in demyelination in the CNS and highlight its effect, particularly on cellular recruitment and cytokine regulation.  (+info)

Interleukin-1beta promotes repair of the CNS. (3/102)

Interleukin-1beta (IL-1beta) is a proinflammatory cytokine associated with the pathophysiology of demyelinating disorders such as multiple sclerosis and viral infections of the CNS. However, we demonstrate here that IL-1beta appears to promote remyelination in the adult CNS. In IL-1beta(-/-) mice, acute demyelination progressed similarly to wild-type mice and showed parallel mature oligodendrocyte depletion, microglia-macrophage accumulation, and the appearance of oligodendrocyte precursors. In contrast, IL-1beta(-/-) mice failed to remyelinate properly, and this appeared to correlate with a lack of insulin-like growth factor-1 (IGF-1) production by microglia-macrophages and astrocytes and to a profound delay of precursors to differentiate into mature oligodendrocytes. Thus, IL-1beta may be crucial to the repair of the CNS, presumably through the induction of astrocyte and microglia-macrophage-derived IGF-1.  (+info)

The protective role of nitric oxide in a neurotoxicant-induced demyelinating model. (4/102)

Demyelination is often associated with acute inflammatory events involving the recruitment-activation of microglia/macrophage, astrocytes, and leukocytes. The ultimate role of inflammatory products in demyelinating disease and in the survival of oligodendrocytes, the myelin forming cells, is unresolved. The current study examines the role of inducible NO synthase (iNOS)-derived NO in a neurotoxicant-induced model of demyelination. NO levels were greatly elevated in the midline corpus callosum during demyelination in genetically intact C57BL/6 mice, and this NO was due solely to the induction of iNOS, as the correlates of NO were not found in mice lacking iNOS. C57BL/6 mice lacking iNOS exhibited more demyelination, but did not display an increased overall cellularity in the corpus callosum, attributable to an unimpeded microglia/macrophage presence. An enhanced course of pathology was noted in mice lacking iNOS. This was associated with a greater depletion of mature oligodendrocytes, most likely due to apoptosis of oligodendrocytes. Microglia and astrocytes did not undergo apoptosis during treatment. Our results suggest a moderately protective role for NO during acute inflammation-association demyelination.  (+info)

Absence of fibroblast growth factor 2 promotes oligodendroglial repopulation of demyelinated white matter. (5/102)

This study takes advantage of fibroblast growth factor 2 (FGF2) knock-out mice to determine the contribution of FGF2 to the regeneration of oligodendrocytes in the adult CNS. The role of FGF2 during spontaneous remyelination was examined using two complementary mouse models of experimental demyelination. The murine hepatitis virus strain A59 (MHV-A59) model produces focal areas of spinal cord demyelination with inflammation. The cuprizone neurotoxicant model causes extensive corpus callosum demyelination without a lymphocytic cell response. In both models, FGF2 expression is upregulated in areas of demyelination in wild-type mice. Surprisingly, in both models, oligodendrocyte repopulation of demyelinated white matter was significantly increased in FGF2 -/- mice compared with wild-type mice and even surpassed the oligodendrocyte density of nonlesioned mice. This dramatic result indicated that the absence of FGF2 promoted oligodendrocyte regeneration, possibly by enhancing oligodendrocyte progenitor proliferation and/or differentiation. FGF2 -/- and +/+ mice had similar oligodendrocyte progenitor densities in normal adult CNS, as well as similar progenitor proliferation and accumulation during demyelination. To directly analyze progenitor differentiation, glial cultures from spinal cords of wild-type mice undergoing remyelination after MHV-A59 demyelination were treated for 3 d with either exogenous FGF2 or an FGF2 neutralizing antibody. Elevating FGF2 favored progenitor proliferation, whereas attenuating endogenous FGF2 activity promoted the differentiation of progenitors into oligodendrocytes. These in vitro results are consistent with enhanced progenitor differentiation in FGF2 -/- mice. These studies demonstrate that the FGF2 genotype regulates oligodendrocyte regeneration and that FGF2 appears to inhibit oligodendrocyte lineage differentiation during remyelination.  (+info)

Insulin-like growth factor (IGF) signaling through type 1 IGF receptor plays an important role in remyelination. (6/102)

We examined the role of IGF signaling in the remyelination process by disrupting the gene encoding the type 1 IGF receptor (IGF1R) specifically in the mouse brain by Cre-mediated recombination and then exposing these mutants and normal siblings to cuprizone. This neurotoxicant induces a demyelinating lesion in the corpus callosum that is reversible on termination of the insult. Acute demyelination and oligodendrocyte depletion were the same in mutants and controls, but the mutants did not remyelinate adequately. We observed that oligodendrocyte progenitors did not accumulate, proliferate, or survive within the mutant mice, compared with wild type, indicating that signaling through the IGF1R plays a critical role in remyelination via effects on oligodendrocyte progenitors.  (+info)

Insulin-like growth factor I gene expression is induced in astrocytes during experimental demyelination. (7/102)

To investigate insulin-like growth factor I (IGF-I) and IGF-I receptor gene expression during experimental demyelination and myelin regeneration, young mice were fed cuprizone (( bis(cyclohexanone) oxaldihydrazone )). This copper-chelating agent produces demyelination in the corpus callosum and superior cerebellar peduncles, and when treatment is stopped, there is rapid remyelination. At intervals during cuprizone treatment and recovery, brain sections were hybridized with specific probes and immunostained with antibodies to determine the localization and relative amounts of IGF-I and IGF-I receptor mRNAs and peptides. In untreated littermates, IGF-I and IGF-I receptor mRNAs and peptides were not detected in white matter. In cuprizone-treated mice, high levels of both IGF-I mRNA and peptide were expressed by astrocytes in areas of myelin breakdown. Astrocyte IGF-I expression decreased rapidly during recovery and oligodendroglial expression of myelin-related genes increased. In severely demyelinated areas, immature oligodendroglia exhibited a transient increase in IGF-I receptor mRNA and peptide immunoreactivity during early recovery. This highly specific pattern of IGF-I induction in astrocytes during demyelination and the expression of the IGF-I receptor in regenerating oligodendrocytes during recovery suggest that IGF-I functions in the regulation of oligodendrocyte and myelin metabolism in vivo.  (+info)

Functional genomic analysis of remyelination reveals importance of inflammation in oligodendrocyte regeneration. (8/102)

Tumor necrosis factor alpha (TNFalpha), a proinflammatory cytokine, was shown previously to promote remyelination and oligodendrocyte precursor proliferation in a murine model for demyelination and remyelination. We used Affymetrix microarrays in this study to identify (1) changes in gene expression that accompany demyelination versus remyelination and (2) changes in gene expression during the successful remyelination of wild-type mice versus the unsuccessful attempts in mice lacking TNFalpha. Alterations in inflammatory genes represented the most prominent changes, with major histocompatibility complex (MHC) genes dramatically enhanced in microglia and astrocytes during demyelination, remyelination, and as a consequence of TNFalpha stimulation. Studies to examine the roles of these genes in remyelination were then performed using mice lacking specific genes identified by the microarray. Analysis of MHC-II-null mice showed delayed remyelination and regeneration of oligodendrocytes, whereas removal of MHC-I had little effect. These data point to the induction of MHC-II by TNFalpha as an important regulatory event in remyelination and emphasize the active inflammatory response in regeneration after pathology in the brain.  (+info)

The cuprizone model is a well-established and investigated paradigm to study demyelination and remyelination in rodents. Cuprizone is usually administrated by mixing in the powdered or pelleted rodent chow. However, since cuprizone is sensitive to the environment and the consumption of it varies between different animals, the major issue is the discrepancy in demyelination of the animals. This study reports the development of the cuprizone model by gavage administrations in mice. Following testing a series of doses of cuprizone, 400 mg/kg/day was found to be the best dosage to induce dramatic and consistent demyelination after 5 weeks of administration; while remyelination quickly occurred after 9 days of cuprizone withdrawal ...

Previous studies have clearly demonstrated the indispensable role of IL-17 in the induction and pathogenesis of EAE, which resembles the pattern I and II MS lesions driven by T cell-mediated autoimmune inflammatory response. In this study, we show for the first time that IL-17-mediated signaling plays a critical role in cuprizone-induced demyelination, which shares similarities with pattern III MS lesions associated with apoptosis of myelin-forming oligodendrocytes and pronounced loss of oligodendrocytes. Interestingly, mice deficient in IL-17A, IL-17RC, and adaptor protein Act1 (of IL-17R) displayed diminished demyelination, microglial accumulation, and leukocyte infiltration compared with that in wild-type mice in response to cuprizone. Importantly, astrocytes are highly responsive to IL-17 in vitro, and selective deletion of Act1 in astrocytes ameliorated cuprizone-induced demyelination. Together, these results suggest that IL-17-mediated signaling in astrocytes contributes to the ...

Neurotrophin signaling impacts development and health of oligodendrocyte lineage cells. Brain-derived neurotrophic factor (BDNF) has been of particular interest. BDNF increases DNA synthesis in cultured basal forebrain oligodendrocyte progenitors (Vant Veer et al., 2009) and enhances oligodendrocyte differentiation to myelin protein-expressing cells (Du et al., 2006). Moreover, BDNF deficient mice exhibit deficits in progenitors and myelin protein expression (Vondran et al., 2010) and the conditional knock-out of the BDNF receptor TrkB from mature, MBP+ oligodendrocytes results in reduced myelin thickness in both the spinal cord and the corpus callosum (Wong et al., 2013).. These effects may be relevant to in vivo demyelination. For example, in the cuprizone demyelination model expression of BDNF is decreased in the corpus callosum, and animals deficient in BDNF exhibit a more severe loss of myelin protein in the lesioned corpus callosum than do their wild-type littermates (VonDran et al., ...

The present study aimed to orally deliver methylthioadenosine (MTA) to the brain employing solid lipid nanoparticles (SLNs) for the management of neurological conditions like multiple sclerosis. The stearic acid-based SLNs were below 100 nm with almost neutral zeta potential and offered higher drug entrapment and drug loading. Cuprizone-induced demyelination model in mice was employed to mimic the multiple sclerosis-like conditions. It was observed that the MTA-loaded SLNs were able to maintain the normal metabolism, locomotor activity, motor coordination, balancing, and grip strength of the rodents in substantially superior ways vis-à-vis plain MTA. Histopathological studies of the corpus callosum and its subsequent staining with myelin staining dye luxol fast blue proved the potential of MTA-loaded SLNs in the remyelination of neurons. The pharmacokinetic studies provided the evidences for improved bioavailability and enhanced bioresidence supporting the pharmacodynamic findings. The studies ...

Acute demyelination following radiotherapy for glioma: a cautionary tale | Practical Neurology  Acute demyelination following radiotherapy for glioma: a cautionary tale | Practical Neurology
Radiotherapy is the mainstay of treatment after surgery for high-grade gliomas and is usually well tolerated. Radiation toxicity in the brain is usually classified according to the timing of side effects in relation to treatment, as either acute (during radiotherapy), early delayed (within 12 weeks of radiotherapy) or late delayed (months to years after radiotherapy). We report two cases of young women who developed severe acute demyelination within 4 months of radiotherapy for glioma, one of whom had a previous history of transverse myelitis. Both improved with corticosteroids and remain in tumour remission. These cases emphasise the importance of careful discussion with patients before starting radiotherapy if there is a previous history of central nervous system demyelination or multiple white matter lesions on MRI. ...

Probing mouse brain microstructure using oscillating gradient diffusion MRI. | Kennedy Krieger Institute  Probing mouse brain microstructure using oscillating gradient diffusion MRI. | Kennedy Krieger Institute
High resolution diffusion tensor images of the mouse brain were acquired using the pulsed gradient spin echo sequence and the oscillating gradient spin echo sequence. The oscillating gradient spin echo tensor images demonstrated frequency-dependent changes in diffusion measurements, including apparent diffusion coefficient and fractional anisotropy, in major brain structures. Maps of the rate of change in apparent diffusion coefficient with oscillating gradient frequency revealed novel tissue contrast in the mouse hippocampus, cerebellum, and cerebral cortex. The observed frequency-dependent contrasts resembled neuronal soma-specific Nissl staining and nuclei-specific 4,6-diamidino-2-phenylindole (DAPI) staining in the mouse brain, which suggests that the contrasts might be related to key features of cytoarchitecture in the brain. In the mouse cuprizone model, oscillating gradient spin echo-based diffusion MRI revealed significantly higher frequency-dependence of perpendicular diffusivity (λ() ...

Cell therapy promotes axon remyelination in a mouse model - Scienmag: Latest Science and Health News  Cell therapy promotes axon remyelination in a mouse model - Scienmag: Latest Science and Health News
Demyelinating diseases, such as multiple sclerosis and leukodystrophy, are characterized by damage to the protective myelin sheath that surrounds the axons of neurons. This demyelination can be caused by an autoimmune response or impaired myelin production by oligodendrocytes.. A new report in JCI Insight from Arjun Saha and colleagues at Duke University demonstrates that a cell therapy product called DUOC-01 can accelerate remyelination of axons in mice treated with a demyelinating chemical agent. DUOC-01 cells, which are derived from banked umbilical cord blood, were transplanted into mice following toxic demyelination. DUOC-01 treatment resulted in faster remyelination and promoted the differentiation of oligodendrocyte progenitor cells. These results suggest that a cord blood-derived cell product can promote neuronal repair and remyelination. Future clinical studies will be needed to determine if DUOC-01 cell therapy benefits patients with demyelinating diseases.. ...

A monoclonal natural human IgM protects axons in the absence of remyelination | Journal of Neuroinflammation | Full Text  A monoclonal natural human IgM protects axons in the absence of remyelination | Journal of Neuroinflammation | Full Text
There is much evidence to support the goal of remyelination as a means to prevent axon degeneration and slow deficit progression in neurologic disease [14]. In the year 2000, we reported the identification of a natural human IgM that promoted robust spinal cord remyelination in both the TMEV-IDD and lysolecithin-induced demyelination models [15, 16]. A recombinant form of this human IgM, termed rHIgM22, was expressed in a F3B6 cell line with the assembled IgM containing a mouse J chain [17]. rHIgM22 binds to myelin and the surface of oligodendrocytes (OL) and in pre-clinical studies is effective in vivo at very low doses. A single 0.025 mg/kg intraperitoneal injection of rHIgM22 given to TMEV-IDD mice with demyelination promoted significant remyelination 5 weeks later [18] and increased brainstem NAA concentrations [13], indicating a preservation of axon health [19]. In a recently concluded dose escalation clinical trial in humans with MS, rHIgM22 was tested at doses ranging from 0.025 up to 2 ...

Multiple Sclerosis Research: Remyelination with Citicoline  Multiple Sclerosis Research: Remyelination with Citicoline
Neuroprotective approaches for central nervous system regeneration have not been successful in clinical practice so far and compounds that enhance remyelination are still not available for patients with multiple sclerosis. The objective of this study was to determine potential regenerative effects of the substance cytidine-5-diphospho (CDP)-choline in two different mouse animal models of multiple sclerosis. The effects of exogenously applied CDP-choline were tested in mouse myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis. In addition, the cuprizone-induced mouse model of de- and remyelination was used to specifically test the hypothesis that CDP-choline directly increases remyelination. We found that CDP-choline ameliorated the disease course of experimental autoimmune encephalomyelitis and exerted beneficial effects on myelin, oligodendrocytes and axons. After cuprizone-induced demyelination, CDP-choline effectively enhanced myelin regeneration and ...

The pathogenesis of murine hepatitis virus, strain JHM, was studied in 6- and 12-week-old C57iBL mice. There was 100% mortality in the 6-week-old mice after intracerebral inoculation. The lesions were characterized by necrotizing encephalomyelitis, without demyelination. Intracerebral inoculation of 12-week-old animals, however, resulted in no morbidity or mortality. The 12-week-old animals showed transient virus replication in the brain, spinal cord, and liver, which was cleared by day 14. Histologic examination showed evidence of ongoing demyelination, concomitant remyelination, and hydrocephalus ex vacuo. Although viral antigen was demonstrated by immunofluorescence in the central nervous system of these animals, no infectious virus was recovered, and immunosuppression regimens did not potentiate the disease.. ...

Remyelination in the central nervous system  Remyelination in the central nervous system
Multiple Sclerosis (MS) is an inflammatory disease which causes areas of demyelination in the Central Nervous System (CNS) and affects only humans. Current therapies for MS are focused on anti-inflammatory treatment, which reduce the occurrence and clinical relapses of the disease. However, progressive disability of the disease is related to axonal degeneration. After demyelination, remyelination occurs, which helps repair the demyelinated lesions and protects axons from degeneration. However, this endogenous remyelination is inefficient, and currently there are no therapies available to enhance remyelination. The aim of this thesis was to first characterize a fast and reliable model to study CNS remyelination in vitro, and second to investigate the role of semaphorin 3a (Sema3A) and semaphorin 3f (Sema3F) signaling in CNS remyelination. Various in vivo models have been developed to investigate the pathology of multiple sclerosis, and can be used to test remyelination therapies. However, in vivo ...

Investigating myelination and remyelination in zebrafish  Investigating myelination and remyelination in zebrafish
Central nervous system (CNS) myelination is important for proper nervous system function in vertebrates. In demyelinating diseases such as multiple sclerosis, autoimmune-mediated myelin destruction results in neurological impairment; and although remyelination does occur spontaneously, it is poorly understood and insufficient in humans. Zebrafish (Danio rerio) are known to harbour tremendous regenerative capacity of various CNS tissues; however, there is presently only little knowledge of their myelin repair efficiency. An experimental model of myelin injury in zebrafish would permit study of the mechanisms involved in successful remyelination and could potentially guide the development of novel therapeutic agents for mammalian remyelination. This doctoral thesis describes the characterisation of the novel myelin protein Claudin k in zebrafish, demonstrates the establishment of adult zebrafish as an experimental model for CNS de- and remyelination and explores some mechanisms underlying myelin ...

Magnetization transfer imaging represents an attempt to develop contrast in MR imaging on the basis of submolecular exchange processes that may occur in biological tissue (21). This technique has some clinical and research applications in the study of different CNS disorders (22), because it affords a potential window into the macromolecular environment that is not directly visible using conventional techniques (21). Therefore, it enables the assessment of "invisible" disease in the so-called normal-appearing white matter (23-25), and, with the application of MTR, it provides a means to quantify disease burden (26).. Experimental and human studies support the hypothesis that demyelination and axonal loss are the main contributors to the MTR decrease observed in association with several pathologic conditions, such as experimental autoimmune encephalomyelitis (12), toxic demyelination (27), progressive multifocal leukoencephalopathy (28), human immunodeficiency virus encephalitis (28), and ...

Investigating novel molecular targets for promoting remyelination in the brain  Investigating novel molecular targets for promoting remyelination in the brain
Dr Jessica Fletcher, funded by an MS Research Australia Postdoctoral Fellowship, with the support of the Trish MS Research Foundation, has been working with Dr Simon Murray and Dr Junhua Xiao at The University of Melbourne, investigating novel molecular targets for promoting remyelination in the brain. Myelin coats the nerve cells in the brain and spinal cord. In MS there is damage to the myelin, and in the early stages of the disease there is some ability to repair the myelin, a process known as remyelination. Over time the bodys ability to remyelinate becomes impaired, leading to incomplete repair and contributing to the progression of MS symptoms. It is crucial to identify potential new treatment targets that can promote myelin repair, prevent nerve damage and halt MS disease progression.. Dr Fletcher has been working on a nerve growth factor, known as brain-derived neurotrophic factor (BDNF), which has been found to promote myelination by activating different receptors, or docking stations, ...

Remyelination - Wikipedia  Remyelination - Wikipedia
Remyelination is the process of propagating oligodendrocyte precursor cells to form oligodendrocytes to create new myelin sheaths on demyelinated axons in the CNS. This is a process naturally regulated in the body and tends to be very efficient in a healthy CNS. The process creates a thinner myelin sheath than normal, but it helps to protect the axon from further damage, from overall degeneration, and proves to increase conductance once again. Demyelinating diseases, such as Multiple Sclerosis, have been of utmost interest within the last couple of decades. Recent research is uncovering some of the many unknown pathways involved with remyelination in hopes of battling demyelinating diseases like MS which can ultimately cripple a person. While no treatment exists yet in preventing remyelination failure in the chronic stages of these diseases, future research may yet prove to unlock key pathways that can be targeted. Remyelination is activated and regulated by a variety of factors surrounding ...

Impaired myelination and reduced brain ferric iron in the mouse model of mucolipidosis IV | Disease Models & Mechanisms  Impaired myelination and reduced brain ferric iron in the mouse model of mucolipidosis IV | Disease Models & Mechanisms
In the present study, we show that hypomyelination in the MLIV mouse brain is associated with decreased expression of both precursor and mature oligodendrocyte markers, as well as a decrease in the number of postmitotic oligodendrocytes. Our observation of delayed myelin deposition during early postnatal brain development highlights the developmental character of brain pathology in MLIV. Interestingly, our data also indicate that the fate of developing oligodendrocytes is affected differently in the white (corpus callosum) versus gray (neocortex) matter of the brain as indicated by changes in CC+ cell counts (Fig. 4) or PLP and MBP staining intensities in these brain regions. This suggests that the tissue microenvironment and factors released by neighboring cells can contribute to the ability of Mcoln1−/− oligodendrocytes to develop, survive and/or produce myelin. Despite these region-specific changes within the brain, our data demonstrate that TRPML1 is an important regulator of ...

Multiple Sclerosis Research: CXCR7 another target for remyelination  Multiple Sclerosis Research: CXCR7 another target for remyelination
Current treatment modalities for the neurodegenerative disease multiple sclerosis (MS) use disease-modifying immunosuppressive compounds but do not promote repair. Although several potential targets that may induce myelin production have been identified, there has yet to be an approved therapy that promotes remyelination in the damaged central nervous system (CNS). Remyelination of damaged axons requires the generation of new oligodendrocytes from oligodendrocyte progenitor cells (OPCs). Although OPCs are detected in MS lesions, repair of myelin is limited, contributing to progressive clinical deterioration. In the CNS, the chemokine CXCL12 promotes remyelination via CXCR4 activation on OPCs, resulting in their differentiation into myelinating oligodendrocytes. Although the CXCL12 scavenging receptor CXCR7/ACKR3 (CXCR7) is also expressed by OPCs, its role in myelin repair in the adult CNS is unknown. ...

Demyelination of CNS axons occurs in a number of pathological conditions, including multiple sclerosis and contusion-type spinal cord injury. The demyelination can be repaired by remyelination in both humans and rodents, and even within the CNS remyelination can be achieved by endogenous and/or exogenous Schwann cells, the myelinating cells of the PNS. Remyelinated axons can often conduct impulses securely, but the organization of ion channels at long-term remyelinated nodes is not known. In the present study, the expression of voltage-gated sodium (Nav) and potassium (Kv) channels along central axons remyelinated by endogenous Schwann cells has been studied in lesions induced more than 1 year previously by the intraspinal injection of ethidium bromide (EB). The expression of the channels at long-term nodes formed by Schwann cell remyelination has been compared with that present in nascent nodes formed in the adult at 18 and 23 days post-EB injection. Immunohistochemical studies revealed that ...

Loss of oligodendrocytes in multiple sclerosis (MS) leads to demyelination and axonal dysfunction and transection. Myelin repair, or remyelination, not only restores proper axonal conduction, but also protects axons from degeneration. Oligodendrocytes are myelin-producing cells and are generated from oligodendrocyte progenitor cells (OPCs). Although spontaneous production of oligodendrocytes and consequent remyelination do occur in early phases of MS, the efficiency decreases over time as the disease progresses. Therapeutic interventions to stimulate oligodendrocyte production and remyelination efficiency are likely to reduce disease progression and neurological disability ...

Promoting remyelination in the central nervous system  Promoting remyelination in the central nervous system
Early in 2016 Dr David Gonsalvez was awarded a prestigious Betty Cuthbert Postdoctoral Fellowship co-funded by National Health and Medical Research Council / MS Research Australia, with MS Research Australias contribution provided with full funding support from the Trish MS Research Foundation. MS results from the damage and loss of myelin, the conductive layer present around nerve fibres in the brain and spinal cord. This makes the nerve fibres unable to transmit their electrical signals, but also leaves the nerves very vulnerable to permanent damage. Myelin can be repaired, but this process is often incomplete and the failure of remyelination is thought to contribute to the development of the secondary progressive form of MS. At the moment there are no treatment options available that promote the repair of myelin to restore lost function and prevent further disability in people with MS. It is known the myelin repair is inhibited by some of the chemicals and physical features associated with ...

New cases of central nervous system demyelination and exacerbations of pre-existing disease have been reported in patients with rheumatoid arthritis following exposure to TNF inhibitors. However, as in the case of lymphoma, any causal relationship remains controversial and unproven. In fact, TNF-a has been implicated in the pathogenesis of multiple sclerosis, and because of this there have been studies of TNF inhibitors in this disease. In a Phase I open-label study, two patients with rapidly progressing multiple sclerosis refractory to high-dose intravenous corticosteroids were treated with intravenous infliximab.

Multiple sclerosis involves an aberrant autoimmune response and progressive failure of remyelination in the central nervous system. Prevention of neural degeneration and subsequent disability requires remyelination through the generation of new oligodendrocytes, but current treatments exclusively target the immune system. Oligodendrocyte progenitor cells are stem cells in the central nervous system and the principal source of myelinating oligodendrocytes. These cells are abundant in demyelinated regions of patients with multiple sclerosis, yet fail to differentiate, thereby representing a cellular target for pharmacological intervention. To discover therapeutic compounds for enhancing myelination from endogenous oligodendrocyte progenitor cells, we screened a library of bioactive small molecules on mouse pluripotent epiblast stem-cell-derived oligodendrocyte progenitor cells. Here we show seven drugs function at nanomolar doses selectively to enhance the generation of mature oligodendrocytes ...

The present study identifies cAMP‐Erk1/2/p38Mapk‐Creb1 signalling as a functionally important intracellular signalling cascade for CNS remyelination that is regulated at the earliest stages of OPC differentiation. These data complement previous studies demonstrating a role for Erk2 and p38Mapk (Chew et al, 2010) as positive regulators of oligodendrocyte differentiation in vitro and during developmental myelination. Loss of ERK2 attenuates OPC differentiation and leads to a delay but not a complete arrest in the appearance of differentiated oligodendrocytes in vivo (Fyffe‐Maricich et al, 2011). Similarly, p38Mapk inhibition decreases OPC differentiation and Mbp expression without effecting either proliferation or survival (Chew et al, 2010). Reporter assay studies have demonstrated that p38MAPK activity up‐regulates the activity and/or expression of transcription factors that can bind the 2 kb mouse MBP promoter. However, p38MAPK can also antagonize ERK, JNK, c‐Jun phosphorylation. We ...

The polyanion-binding cell surface receptor TREM2 is expressed on myeloid cell populations, including microglia of the CNS. Individuals with inactivating mutations in TREM2 or TYROBP, which encodes the TREM2 adapter DAP12, develop Nasu-Hakola disease, a rare, lethal dementia that manifests in early adulthood and is characterized by demyelinating lesions. The link between loss of TREM2 function and dysfunctional myelination is not clear. Pietro Poliani, Yaming Wang, and colleagues at the University of Brescia School of Medicine used murine models to investigate a possible role for microglial TREM2 in myelin repair following injury. An age-dependent expansion of microglia was absent in the brains of mice lacking TREM2, and the microglia that were present were notably smaller and dystrophic. In a chronic toxin model of demyelination, loss of TREM2 severely impaired remyelination and removal of myelin debris during prolonged toxin exposure. Further, Trem2 deletion altered demyelination- and ...

Disease-specific therapy of idiopathic inflammatory demyelinating disorders. - Semantic Scholar  Disease-specific therapy of idiopathic inflammatory demyelinating disorders. - Semantic Scholar
Central nervous system idiopathic inflammatory demyelinating disorders are a heterogenous group of diseases that share inflammation and demyelination as key features. Although the exact pathophysiology remains to be fully unveiled, these conditions are challenging to clinicians who seek specific therapeutic options for their patients. For two of these conditions, multiple sclerosis and neuromyelitis optica, there are now several possible therapies in an ever-evolving field. This review will touch on the various idiopathic inflammatory demyelinating disorders and discuss the various treatment options currently available.

A novel method has been developed for the preparation of nearly pure separate cultures of astrocytes and oligodendrocytes. The method is based on (a) the absence of viable neurons in cultures prepared from postnatal rat cerebra, (b) the stratification of astrocytes and oligodendrocytes in culture, and (c) the selective detachment of the overlying oligodendrocytes when exposed to sheer forces generated by shaking the cultures on an orbital shaker for 15--18 h at 37 degrees C. Preparations appear greater than 98% pure and contain approximately 1-2 x 10(7) viable cells (20--40 mg of cell protein). Three methods were used to characterize these two culture t ypes. First, electron microscopic examination was used to identify the cells in each preparation (mixed and separated cultures of astrocytes and oligodendrocytes) and to assess the purity of each preparation. Second, two oligodendroglial cell markers, 2,3-cyclic nucleotide 3-phosphohydrolase (EC 3.1.4.37) and glycerol phosphate dehydrogenase ...

Multiple sclerosis, which is the most common cause of chronic neurological disability in young adults, is an inflammatory, demyelinating, and neurodegenerative disease of the CNS, which leads to the formation of multiple foci of demyelinated lesions in the white matter. The diagnosis is based currently on magnetic resonance image and evidence of dissemination in time and space. However, this could be facilitated if biomarkers were available to rule out other disorders with similar symptoms as well as to avoid cerebrospinal fluid analysis, which requires an invasive collection. Additionally, the molecular mechanisms of the disease are not completely elucidated, especially those related to the neurodegenerative aspects of the disease. The identification of biomarker candidates and molecular mechanisms of multiple sclerosis may be approached by proteomics. In the last 10 years, proteomic techniques have been applied in different biological samples (CNS tissue, cerebrospinal fluid, and blood) from ...

Multiple sclerosis (MS) is a chronic disabling disease of the central nervous system commonly affecting young adults. Pathologically, there are patches of inflammation (plaques) with demyelination of axons and oligodendrocyte loss. There is a global latitude gradient in MS prevalence, and incidence of MS is increasing (particularly in females). These changes suggest a major role for environmental factors in causation of disease. We have reviewed the evidence and potential mechanisms of action for three exposures: vitamin D, Epstein Barr virus and cigarette smoking. Recent advances supporting gene-environment interactions are reviewed. Further research is needed to establish mechanisms of causality in humans and to explore preventative strategies.

Our research group is interested in the molecular mechanisms defining the epigenetic state of stem/progenitor cells. We are particularly focused on how interplay between transcription factors, non-coding RNAs and chromatin modifying enzymes contributes to the transition between epigenetic states in oligodendrocyte precursor cells, with the aim to design epigenetic based-therapies to induce regeneration (remyelination) in demyelinating diseases, such as multiple sclerosis.

In many multiple sclerosis (MS) patients CNS repair fails or is incomplete whereas in others the disease is accompanied by extensive repair of demyelinated lesions.We have described significant differences in the ability of two strains ofmice to repair CNS damage following Theilers virusinduced demyelination: FVB/NJ (FVB) mice repair damaged myelin spontaneously and completely,whereas B10.D1-H2q/SgJ (B10.Q)mice are deficient in the repair process. A QTL analysis was performed to identify genetic loci that differentially regulate CNS repair ...

The most common neurological deficits in children after surgery for congenital heart disease are fine and gross motor deficits. Recent magnetic resonance imaging studies have demonstrated a significant number of newly developed white matter (WM) lesions in infants after surgery. The present study describes region-specific WM development in the juvenile porcine brain, which is similar in developmental stage to the human newborn. Acute and long-term cellular responses to cardiopulmonary bypass in oligodendrocyte lineages and neuron-axonal elements, which are the most prominent cell populations in WM, have been observed. A uniquely susceptible cellular target of cardiopulmonary bypass-induced WM injury in the oligodendrocyte lineage, as well as maturation-dependent vulnerability of developing WM, was found. Oligodendrocyte progenitor cells, which mediate WM recovery function, are highly resistant to cardiopulmonary bypass-induced injury. Interestingly, oligodendrocyte progenitor cell number ...

Experimental2
  • This targeted anti-inflammatory agent improves physical deficits in experimental autoimmune encephalomyelitis (EAE), an animal model of MS. Here, we sought to determine whether tuftsin is also effective in combination with benztropine, an FDA-approved drug that stimulates remyelination, in both EAE and in the cuprizone model of demyelination. (frontiersin.org)
  • The EAE (experimental autoimmune encephalomyelitis) series of MS models are widely used to test therapies targeting the inflammation component of MS, while MS models where demyelination is induced by cuprizone, lysolecithin, or ethidium bromide are increasingly being used to test therapeutic candidates.

  • Animals were fed with 0.2% w/w cuprizone added to ground breeder chow ad libitum for six weeks. (bvsalud.org)
Alterations2
  • This study aimed at evaluating the ameliorative capability of M. oleifera in cuprizone-induced behavioral and histopathological alterations in the prefrontal cortex and hippocampus of Wistar rats. (bvsalud.org)
  • Lack of cuprizone-induced demyelination in the murine spinal cord despite oligodendroglial alterations substantiates the concept of site-specific susceptibilities of the central nervous system. (tiho-hannover.de)

Weeks3
  • BM-MSCs (2 × 10 6 in 1 milliliter medium) were administered intraperitoneally for two consecutive weeks at the end of the forth weeks of cuprizone administration. (ac.ir)
  • Four groups of rats were treated with normal saline, cuprizone, M. oleifera and a combination of M. oleifera and cuprizone, for five weeks. (bvsalud.org)
  • Cuprizone was orally administered at a dose of 400 mg/kg/day by oral gavage for 5 weeks. (medworm.com)
Rats2
  • Thus, we aimed to examine changes in the electromyographic characteristics of female and male Sprague-Dawley rats with cuprizone-induced demyelination. (springer.com)
  • Notably, electrophysiological observations reveal that cuprizone affects both female and male rats, but males are more sensitive. (springer.com)
Inflammatory1
  • Importantly, tuftsin is required to transform the inflammatory CNS environment normally present in EAE/MS into one of an anti-inflammatory nature, and benztropine is required in the cuprizone model to improve remyelination. (frontiersin.org)

Administration1
  • however, administration of M. oleifera significantly reversed the neuropathological deficits induced by cuprizone. (bvsalud.org)
Effects1
  • however, the effects of cuprizone on the functions of the peripheral nervous system, as well as differential effects it may exert on males and females, have not yet been studied. (springer.com)

Study1
  • This is the first study showing gender differences for the peripheral neurotoxicity of cuprizone. (springer.com)
Animals1
  • During the second course of Cuprizone, the animals showed greater resistance to the toxin and demyelination occurred slowly and was complete only after prolonged periods. (docme.ru)
Treatment1
  • Linagliptin treatment improved behavioural and motor abnormalities induced by cuprizone, as demonstrated by open field, rotarod and grip strength tests. (bioportfolio.com)
Cells1
  • BM-derived cells are recruited in a CCR2-dependent manner into demyelinating sites of the CNS in the cuprizone model. (rupress.org)
