In most patients the disease evolves into a chronic progressive phase characterized by continuous accumulation of neurological deficits. While treatment of relapsing-remitting MS (RRMS) has improved dramatically over the last decade, the therapeutic options for chronic progressive MS, both primary and secondary, are still limited. In order to find new pharmacological targets for the treatment of chronic progressive MS, the mechanisms of the underlying neurodegenerative process that becomes apparent as the disease progresses need to be elucidated. New animal models with prominent and widespread progressive degenerative components of MS have to be established to study both inflammatory and non-inflammatory mechanisms of neurodegeneration. Here, we discuss disease mechanisms and treatment strategies for chronic progressive MS."],["dc.description.sponsorship","ERC; EMBO"],["dc.identifier.isi","000281436200014"],["dc.identifier.pmid","21358979"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/19037"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Bentham Science Publ Ltd"],["dc.relation.issn","1570-159X"],["dc.title","Chronic Progressive Multiple Sclerosis - Pathogenesis of Neurodegeneration and Therapeutic Strategies"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

We reasoned that microRNAs (miRNAs) could play an important role in this process by regulating crucial developmental genes. Microarray profiling of cultured oligodendrocytes identified the miR-17-92 miRNA cluster as highly enriched in oligodendrocytes. We specifically deleted the miR-17-92 cluster in oligodendrocytes using 2',3'-cyclic nucleotide 3' phosphodiesterase (Cnp)-Cre mice. Absence of miR-17-92 leads to a reduction in oligodendrocyte number in vivo and we find that the expression of these miRNAs in primary cultures of oligodendrocyte precursor cells promotes cell proliferation by influencing Akt signaling. Together, these results suggest that the miRNA pathway is essential in determining oligodendroglial cell number and that the miR-17-92 cluster is crucial in this process."],["dc.description.sponsorship","ERC; EMBO YIP; Boehringer Ingelheim Fonds"],["dc.identifier.doi","10.1242/dev.050633"],["dc.identifier.isi","000278559900006"],["dc.identifier.pmid","20504959"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/19507"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Company Of Biologists Ltd"],["dc.relation.issn","0950-1991"],["dc.title","Control of oligodendroglial cell number by the miR-17-92 cluster"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Here, we studied the formation of myelin membrane sheets in a neuron-glia co-culture system. We applied different microscopy techniques to visualize lipid packing and dynamics in the oligodendroglial plasma membrane. We used the fluorescent dye Laurdan to examine the lipid order with two-photon microscopy and observed that neurons induce a dramatic lipid condensation of the oligodendroglial membrane. On a nanoscale resolution, using stimulated emission depletion and fluorescence resonance energy transfer microscopy, we demonstrated a neuronal-dependent clustering of GalC in oligodendrocytes. Most importantly these changes in lipid organization of the oligodendroglial plasma membrane were not observed in shiverer mice that do not express the myelin basic protein. Our data demonstrate that neurons induce the condensation of the myelin-forming bilayer in oligodendrocytes and that MBP is involved in this process of plasma membrane rearrangement. We propose that this mechanism is essential for myelin to perform its insulating function during nerve conduction."],["dc.identifier.doi","10.1038/sj.emboj.7601376"],["dc.identifier.gro","3143596"],["dc.identifier.isi","000242214900001"],["dc.identifier.pmid","17036049"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/1128"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","0261-4189"],["dc.title","Myelin basic protein-dependent plasma membrane reorganization in the formation of myelin"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]

Whether oligoclonal bands (OCBs) represent unspecific disease bystanders or active components in MS pathology is an open question. The aim of this study was to develop a method to quantify and compare the reactivity of cerebrospinal fluid (CSF) antibodies from patients with and without MS. Methods: We collected CSF from 262 patients from two different cohorts, which included 148 patients with MS and 114 with other neurological diseases (OND). We established a highly sensitive electrochemiluminescence (ECL)-based assay to measure CSF antibody reactivity against purified myelin particles and biotin anchored liposomes. The diagnostic value of the ECL score against myelin particles was assessed with receiver operating characteristic curves. Results: CSF from patients with MS have higher reactivity toward purified myelin particles as compared to those with OND with OCBs. Using liposomes with defined lipid compositions and myelin particles from ceramide synthase 2 (CerS2) knockout mice, we find that some of the CSF antibody reactivity is directed against cerebrosides. Conclusion: The ECL-based assay system expands the currently available toolbox for the detection of autoantibodies in MS and related diseases."],["dc.identifier.doi","10.1002/acn3.264"],["dc.identifier.isi","000367240500006"],["dc.identifier.pmid","26734662"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/35253"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","2328-9503"],["dc.title","Quantified CSF antibody reactivity against myelin in multiple sclerosis"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
