The membrane protein Nogo-A inhibits neurite outgrowth and regeneration in the injured central nervous system, primarily because of its expression in oligodendrocytes. Hence, deletion of Nogo-A enhances regeneration following spinal cord injury. Yet, the effects of Nogo-A deletion on general behavior and cognition have not been explored. The possibility of potential novel functions of Nogo-A beyond growth inhibition is strongly suggested by the presence of subpopulations of neurons also expressing Nogo-A - not only during development but also in adulthood. We evaluated here Nogo-A(-/-) mice in a series of general basic behavioral assays as well as functional analyses related to brain regions with notable expression levels of Nogo-A. The SHIRPA protocol did not show any major basic behavioral changes in Nogo-A(-/-) mice. Anxiety-related behavior, pain sensitivity, startle reactivity, spatial learning, and associative learning also appeared indistinguishable between Nogo-A(-/-) and control ...

The hippocampal formation has been shown to be particularly vulnerable to the neurotoxic effects of chronic ethanol consumption. It was hypothesized that this damage was due to the disruption of the expression of neurotrophic factors and certain other proteins within the hippocampus. By using real-time reverse transcription-polymerase chain reaction (RT-PCR) techniques, this study aimed to determine whether chronic ethanol consumption could alter the mRNA expression level of brain-derived neurotrophic factor (BDNF), glial-derived neurotrophic factor (GDNF), and oligodendrocyte myelin glycoprotein (OMgp) in the hippocampus. Wistar male rats received an unrestricted access to a liquid diet containing 5% (v/v) ethanol as the sole source of fluid from 10 to 29 weeks of age. Control rats had unlimited access to a liquid diet containing an isocaloric amount of sucrose. We found that chronic ethanol consumption did not cause significant changes in the levels of mRNA for BDNF and GDNF. However, OMgp mRNA showed

Following unilateral lesion of the primary motor cortex, the reorganization of callosal projections from the intact hemisphere to the ipsilesional premotor cortex (PM) was investigated in 7 adult macaque monkeys, in absence of treatment (control; n = 4) or treated with function blocking antibodies against the neurite growth inhibitory protein Nogo-A (n = 3). After functional recovery, though incomplete, the tracer biotinylated dextran amine (BDA) was injected in the ipsilesional PM. Retrogradely labelled neurons were plotted in the intact hemisphere and their number was normalized with respect to the volume of the core of BDA injection sites. (1) The callosal projections to PM in the controls originate mainly from homotypic PM areas and, but to a somewhat lesser extent, from the mesial cortex (cingulate and supplementary motor areas). (2) In the lesioned anti-Nogo-A antibody-treated monkeys, the normalized number of callosal retrogradely labelled neurons was up to several folds higher than in ...

While neurons in the central nervous system have the capacity to regenerate their axons after injury, they fail to do so, in part because regeneration is limited by growth inhibitory proteins present in CNS myelin. Myelin-associated glycoprotein (MAG) was the first myelin-derived growth inhibitory protein identified, and its inhibitory activity was initially elucidated in 1994 independently by the Filbin lab and the McKerracher lab using cell-based and biochemical techniques, respectively. Since that time we have gained a wealth of knowledge concerning the numerous growth inhibitory proteins that are present in myelin, and we also have dissected many of the neuronal signaling pathways that act as stop signs for axon regeneration. Here we give an overview of the early research efforts that led to the identification of myelin-derived growth inhibitory proteins, and the importance of this family of proteins for understanding neurotrauma and CNS diseases. We further provide an update on how this knowledge

In light of the fact that the main myelin protein PLP is enriched in LE/Lys compartments and undergoes regulated endocytosis and exocytosis (Kramer et al., 2001; Trajkovic et al., 2006), we asked whether endocytic recycling is common to myelin proteins. We first analyzed the steady state localization of myelin proteins in endosomal compartments by co-labeling primary cultured oligodendrocytes with transferrin-FITC or antibodies against LAMP1, which serve as markers for recycling endosomes or LE/Lys, respectively. Although PLP strongly colocalized with LAMP1 in LE/Lys (Fig. 1, top row, magenta in overlay pictures), we observed only a little overlap of MAG and MOG with LAMP1 or transferrin-FITC in endocytic compartments (Fig. 1, middle and bottom row, magenta and yellow color in overlays, respectively). Thus, among the studied myelin proteins, only PLP accumulates in endosomal compartments. However, a transient endosomal localization of MAG and MOG may be missed or underestimated with this type of ...

The distribution of NgR and Nogo-A supports the hypothesis that these two proteins interact at contact sites between axons and myelin. A majority of Nogo-A is expressed by oligodendrocytes in the adult CNS, and a proportion of the protein localizes to the adaxonal membrane. The NgR protein is found throughout axons in the adult and maturing CNS. Expression of NgR is minimal before myelination. The juxtaposed expression of this ligand-receptor pair is detected in the uninjured brain and spinal cord, and there is a modest increase in Nogo-A expression at sites of trauma.. The adjacent cellular expression of Nogo-A and NgR in the intact brain is consistent with the hypothesis that Nogo-A limits axonal sprouting and plasticity as part of normal physiology. A general statement of this theory holds that axon growth and pathfinding are robust during development. After synaptogenesis and myelination, axonal contacts with Nogo-A and other myelin-derived outgrowth inhibitors may serve to stabilize major ...

The Marine Whitney Laboratories, University of Florida, St. Augustine, FL 32080, U.S.A.. Abstract. Peripheral myelin protein 22 (PMP22), also known as growth arrest specific 3 (gas 3), is a disease-linked tetraspan glycoprotein of peripheral nerve myelin and constituent of intercellular junctions in epithelia. To date, our knowledge on the posttranslational modification of PMP22 is limited. Using the CSS-Palm 2.0 software we predicted that cysteine 85 (C85), a highly-conserved amino acid located between the second and third transmembrane domains, is a potential site for palmitoylation. To test this, we mutated C85 to serine (C85S) and established stable cells lines expressing the wild type (Wt) or the C85S-PMP22. In Schwann and Madin-Darby Canine Kidney (MDCK) cells mutating C85 blocked the palmitoylation of PMP22, which we monitored using 17-Octadecynoic acid (17-ODYA). While palmitoylation was not necessary for processing the newly-synthesized PMP22 through the secretory pathway, ...

Our study analysed the immune responses to a more comprehensive range of myelin protein peptides than has been done before. The ELISA studies showed that IgG or IgM autoantibodies to non-glycosylated peptides from the ECD2-PMP22, but not ECD1-PMP22, were present in only 4 out of 37 (10.8%) patients with GBS at presentation. Previous studies showed different results but used different methodology, not quantifying the amount of IgG and IgM.11 14 Our finding of IgG autoantibodies to non-glycosylated ECD-P0 by ELISA in only 1 of 37 patients with GBS is similar to the results from two western blot studies.13 15 In a recent ELISA study, there was no significant increase in IgG antibodies to peptides corresponding to P0 residues 56-71, 70-85 and 180-199 in 48 patients with GBS compared with 38 healthy controls.16 In the same study, IgG antibodies to P2 residue 14-25 were present in 13/30 patients with GBS at the peak of the disease compared with 2/38 healthy controls (p = 0.002). However, there was no ...

Glial cells were isolated from postnatal day 1 H-2Kb-tsA58 transgenic mice that contain the temperature-sensitive SV40 large T antigen oncogene under the control of an interferon-gamma-inducible promoter. A clonal line was isolated that grew rapidly under permissive conditions (33 degrees C in the presence of interferon-gamma), but not under nonpermissive conditions (37 degrees C in the absence of interferon-gamma). Cells expressed mRNAs of mature myelin proteins (myelin basic proteins and proteolipid protein) when grown under either permissive or nonpermissive conditions, but myelin basic proteins were ...

The growth inhibitory nature of injured adult mammalian central nervous system (CNS) tissue constitutes a major barrier to robust axonal outgrowth and functional recovery following trauma or disease. Prototypic CNS regeneration inhibitors are broadly expressed in the healthy and injured brain and spinal cord and include myelin-associated glycoprotein (MAG), the reticulon family member NogoA, oligodendrocyte myelin glycoprotein (OMgp), and chondroitin sulfate proteoglycans (CSPGs).

Charcot-Marie-Tooth disease type 1A (CMT1A) is caused by a 1.4-Mb duplication on chromosome 17p11.2, which contains the peripheral myelin protein 22 (PMP22), a protein primarily expressed in myelinating Schwann cells (1, 2). In this issue, Zhao et al. treated two rodent models of CMT1A with PMP22-targeting antisense oligonucleotides (ASOs)and showed a 35% reduction in PMP22 mRNA (3). This reduction was not only adequate in slowing disease progression, but also improved the CMT1A-associated phenotypes in both models. These results are exciting for CMT1A researchers for several reasons. First, CMT1A is the most common inherited neuropathy, affecting 1:5,000 individuals. Second, severity of CMT1A appears to be dependent on PMP22 copy number, as patients with 4 copies of PMP22 have more severe neuropathy than typical CMT1A patients, who have 3 copies of PMP22 (4). Additionally, patients with missense mutations in PMP22 develop neuropathies that are similar to CMT1A (5). Taken together, these data ...

MS is an inflammatory disease of the CNS. It fits into the group of autoimmune diseases that share allelic variations in common gene regions, including the MHC locus, IL2RA, IL7R, and CD226 (12, 13). However, it has been difficult to demonstrate differences in the frequency of myelin-specific T cells in the circulation of patients with the disease. An early study showed a higher frequency of anti-MOGIgd in the serum of MS patients, but no difference in the T cell proliferative response between healthy subjects and patients with MS (47). A more recent report by Bahbouhi et al. (48) has shown, using a sensitive detection method, increased frequencies of anti-myelin T cells in MS patients. Soluble MHC-peptide complexes allow the detection and isolation of Ag-specific T cells (26), and these recombinant MHC class II tetramers have been successfully used to detect Ag-specific CD4+ T cells for viral, bacterial, and self-antigens (30-42). In this study, we successfully applied this approach to ...

Adult mammalian central nervous system (CNS) axons have very limited capacity of regrowth after injury. In recent years, advances in the field of axonal regeneration have proved that neurons do not regenerate, mainly because of the presence of inhibitory molecules. Myelin-associated proteins limit axonal outgrowth and their blockage improves the regeneration of damaged fiber tracts. Three of these proteins, Nogo, MAG and OMgp, share a common neuronal receptor (NgR), and together represent one of the main hindrances to neuronal regeneration. The recent molecular cloning of Nogo and its receptors opened a new door to the study of axon regeneration. However, many of the elements involved in the myelin inhibitory pathway are still unknown, and the preliminary experiments with knockout mice are rather contradictory. Because of this complexity, Nogo and NgR need to be characterized before precise strategies to promote axon regeneration in the CNS can be designed ...

Figure 2. OMgp inhibits hippocampal LTP. Recordings of fEPSPs at Schaffer collateral-CA1 synapses in acute hippocampal slices of 6- to 8-week-old wild-type mice. A, Slices were treated with OMgp locally applied via the recording pipette to the dendritic field of CA1 neurons. Summary of LTP recordings in the absence (−OMgp; blue squares) or presence (+OMgp; red triangles) of OMgp are shown. fEPSPs were recorded at CA1 synapses, and slopes were plotted against time before and after tetanic stimulation (two trains of stimuli at 100 Hz for 1 s, separated by a 10-s interval). In the absence of OMgp, the mean fEPSP at 55-60 min was 171 ± 2% of baseline (n = 8 slices/6 animals). In the presence of OMgp, the mean fEPSP at 55-60 min was 130 ± 8% of baseline (n = 6 slices/3 animals). The concentration of OMgp in the recording electrode was 1 mg/ml. B, In parallel experiments, hippocampal slices were treated with the control protein AP-Fc. As was done for OMgp, AP-Fc (1 mg/ml) was loaded in the ...

Martin Schwabs expertise is in developmental neurobiology and mechanisms of repair of the brain and spinal cord. In 1985 he postulated the concept of inhibitors of neurite growth as a cause of the absent regeneration of injured fiber tracts in the central nervous system, which was a novel, anti-dogmatic hypothesis. Subsequently, he isolated one of the most potent nerve fiber growth inhibitors, Nogo-A. When this component was blocked, regeneration and functional repair could be shown for the first time in adult rats and monkeys after spinal cord injury. Cell biological studies on the mechanism of action of Nogo-A and its functional role in the developing and adult CNS are a focus of his current work, in parallel to studies on brain and spinal cord repair and currently on-going clinical trial testing the effects of anti-Nogo-A antibodies in paraplegic patients (in collaboration with Novartis).. ...

Some of the myelin sheaths in the cerebellum of normal adult toads exhibit extensive evaginations of their full thickness. These redundant flaps of myelin are collapsed; i.e., they contain no axon and have no lumen. They extend away from the parent axonal myelin sheaths and tend to enfold other myelinated fibers or granule cell perikarya, producing bizarre configurations of myelin and what appear to be partially or completely myelinated cell bodies. In some instances, only the redundant flap of myelin appears in the plane of section, and its attachment to an axonal myelin sheath in another plane is only inferred. Single lamellae of myelin also tend to invest cerebellar granule cells and other processes, and these too appear to fold on themselves producing two- or four-layered segments. It is suggested that there are two phases of myelinogenesis: an initial wrapping phase, followed by a prolonged second phase during which internodes of myelin increase in both length and girth by a process other ...

Myelin is a dielectric (electrically insulating) material that forms a layer, the myelin sheath, usually around only the axon of a neuron. It is essential for the proper functioning of the nervous system. Myelin is an outgrowth of a glial cell. The production of the myelin sheath is called myelination. The production of myelin occurs in the fourteenth week of fetal development, while very little amounts of myelin exist in the brain at the time of birth. During infancy myelination occurs quickly and does not stop until the adolescent stages of life. Because of this rapid myelination, it is essential that children under the age of two receive a diet higher in fats than one of an adult.. Schwann cells supply the myelin for peripheral neurons, whereas oligodendrocytes, specifically of the interfascicular type, myelinate the axons of the central nervous system. Myelin is considered a defining characteristic of the (gnathostome) vertebrates, but it has also arisen by parallel evolution in some ...

The myelin sheath is found surrounding axons of the both the central and peripheral nervous system. Axons may be myelinated or unmyelinated. In myelinated axons the sheath is arranged with small gaps known as the nodes of Ranvier, this is where the action potentials are generated as this is where the majority of the axons ion channels are located. This article shall discuss the myelin sheath, its affect on transmission of signals in the nervous system and relevant clinical conditions.

Recently, diffuse-large-B-cell lymphoma (DLBCL) associated with serum IgM monoclonal component (MC) has been shown to be a very poor prognostic subset although, detailed pathological and molecular data are still lacking. In the present study, the clinicopathological features and survival of IgM-secreting DLBCL were analyzed and compared to non-secreting cases in a series of 151 conventional DLBCL treated with R-CHOP. IgM MC was detected in 19 (12.5%) out of 151 patients at disease onset. In 17 of these cases secretion was likely due to the neoplastic clone, as suggested by the expression of heavy chain IgM protein in the cytoplasm of tumor cells. In IgM-secreting cases immunoblastic features (p

Hello, I am interested in researching the potential role IGF-1 can play in the repair of central nervous system myelin lesions/inflammation,

Myelin sheath serves as an insulator that surrounds the nerves. This includes the nerves in the brain and spinal cord. This layer is made up of fatty substances, as well as protein. Its purpose is to allow impulses to transfer quickly and efficiently along the nerve cells. If the myelin sheath layer is damages the impulses will slow down and it can cause diseases such as multiple sclerosis. In addition, Myelin Sheath is roughly 200 and 800 μm thick and diseases can also thin out the layer causing the level of protection to obviously decrease. ...

In the trial, the MS patients own specially processed white blood cells were used to stealthily deliver billions of myelin antigens into their bodies so their immune systems would recognize them as harmless and develop tolerance to them.. Current therapies for MS suppress the entire immune system, making patients more susceptible to everyday infections and higher rates of cancer.. While the trials nine patients - who were treated in Hamburg, Germany - were too few to statistically determine the treatments ability to prevent the progression of MS, the study did show patients who received the highest dose of white blood cells had the greatest reduction in myelin reactivity.. The primary aim of the study was to demonstrate the treatments safety and tolerability. It showed the intravenous injection of up to 3 billion white blood cells with myelin antigens caused no adverse affects in MS patients. Most importantly, it did not reactivate the patients disease and did not affect their healthy ...
