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 NeurologyAcute 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. ...

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() ...

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.. ...

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 ...

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 ...

Remyelination in the central nervous systemRemyelination 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 zebrafishInvestigating 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 brainInvestigating 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, ...

Research on myelination offers centered on identifying molecules capable of inducing oligodendrocyte (OL) differentiation in an effort to develop strategies that promote functional myelin regeneration in demyelinating disorders. of and gene manifestation, mediated from the connection of SMAD3/4 with Sp1 and FoxO1 transcription factors. Our study is the 1st to demonstrate an autonomous and important part of TGF signaling in OL development and CNS myelination, and may provide new avenues in the treatment of demyelinating diseases. studies have shown that O-2A progenitor cells express TGF1 and that TGF signaling activation exerts an anti-mitogenic effect countering PDGFR signaling, in turn promoting cell cycle arrest (McKinnon et al., 1993). Moreover, Activin-A, a member of the TGF superfamily, has been proposed as one of the cytokines secreted by microglial cells that plays a role in OL regeneration and remyelination (Miron et al., 2013). These scholarly research claim that TGF signaling could be ...

Remyelination - WikipediaRemyelination - 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 ...

We set up the Cambridge Centre for Myelin Repair in 2005, with the aim of developing treatments that promote myelin repair for people with MS.. Since it opened the Cambridge Centre has created a world-class research environment involving researchers from all around the UK - most notably at our Edinburgh Centre for MS Research.. Scientists at both centres have worked together to show that a molecule called RXR-gamma could encourage the brains own stem cells to repair myelin in animal models of MS. Researchers will now test the benefits of a drug that targets RXR-gamma, called bexarotene, in a phase 2 clinical trial.. We announced four more years of funding for the Cambridge Centre in 2016. Researchers will continue to investigate the fundamental mechanisms behind myelin repair, with the hope of developing new treatments.. They will focus on understanding more about the cells capable of repairing myelin, and the impact ageing and lifestyle factors (such as diet and exercise) can have on these ...

Impaired myelination and reduced brain ferric iron in the mouse model of mucolipidosis IV | Disease Models & MechanismsImpaired 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 ...

He told us that in 500 MS patients he has tested now, 100% have CCSVI. He stated the doppler is a wonderful tool of diagnosis and their needs to be training in the technique. He has a hypothesis as to why there are different varieties of screening in high risk subjects- because prognosis is related to the type of malformation. He wants to answer the question if the Liberation procedure is a disease modifying treatment in MS. He will give proof tomorrow that there is plasticity and remyelination in the CNS and the Liberation procedure have proven to activate remyelination in the CNS as shown by MRI ...

Multiple Sclerosis Research: CXCR7 another target for remyelinationMultiple 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. ...

Isoflurane exposure leads to apoptosis of neurons and oligodendrocytes in 20- and 40-day old rhesus macaques | SmartTotsIsoflurane exposure leads to apoptosis of neurons and oligodendrocytes in 20- and 40-day old rhesus macaques | SmartTots
Previously we reported that a 5-hour exposure of 6-day-old (P6) rhesus macaques to isoflurane triggers robust neuron and oligodendrocyte apoptosis. In an attempt to further describe the window of vulnerability to anesthetic neurotoxicity, we exposed P20 and P40 rhesus macaques to 5 h of isoflurane anesthesia or no exposure (control animals). Brains were collected 3 h later and examined immunohistochemically to analyze neuronal and glial apoptosis. Brains exposed to isoflurane displayed neuron and oligodendrocyte apoptosis distributed throughout cortex and white matter, respectively. When combining the two age groups (P20 + P40), the animals exposed to isoflurane had 3.6 times as many apoptotic cells as the control animals. In the isoflurane group, approximately 66% of the apoptotic cells were oligodendrocytes and 34% were neurons. In comparison, in our previous studies on P6 rhesus macaques, approximately 52% of the dying cells were glia and 48% were neurons. In conclusion, the present data ...

  • 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)
Receptor1
  • Toll-Like Receptor 2-Mediated Glial Cell Activation in a Mouse Model of Cuprizone-Induced Demyelination. (uni-muenchen.de)
Microglia2
  • Sulfasalazine alters microglia phenotype by competing endogenous RNA effect of miR-136-5p and long non-coding RNA HOTAIR in cuprizone-induced demyelination. (bioportfolio.com)
  • Microglia polarization by methylprednizolone acetate accelerates cuprizone induced demyelination. (bioportfolio.com)
Rats1
  • Thus, we aimed to examine changes in the electromyographic characteristics of female and male Sprague-Dawley rats with cuprizone-induced demyelination. (springer.com)
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)
Diet2
  • Next, CNS inflammation and demyelination was induced by means of a cuprizone-supplemented diet. (biomedcentral.com)
  • Another group was sacrificed 2 wk after removing cuprizone from the diet to allow remyelination. (rupress.org)
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)
Brain1
  • 1991. A comparison of spongiosis induced in the brain by hexachlorophene, cuprizone and triethyl tin in the Sprague-Dawley rat. (nih.gov)
Vivo1
  • Evidence from a cuprizone-induced model of demyelination, in vitro and in vivo T-cell assays and EAE adoptive transfer experiments indicated that the observed efficacy of this drug results directly from an enhancement of remyelination rather than immune suppression. (nih.gov)
Treatment1
  • Linagliptin treatment improved behavioural and motor abnormalities induced by cuprizone, as demonstrated by open field, rotarod and grip strength tests. (bioportfolio.com)
Study1
  • This is the first study showing gender differences for the peripheral neurotoxicity of cuprizone. (springer.com)
Protein1
  • The Anti-Aging Protein Klotho Enhances Remyelination Following Cuprizone-Induced Demyelination. (bu.edu)
Cells1
  • BM-derived cells are recruited in a CCR2-dependent manner into demyelinating sites of the CNS in the cuprizone model. (rupress.org)
