Reduced levels of a specific myelin-associated oligodendrocytic basic protein isoform in shiverer myelin.
Myelin-associated oligodendrocytic basic protein (MOBP) and myelin basic protein (MBP) share many structural similarities. MOBP is synthesised by mature oligodendrocytes and localised at the major dense line (MDL), suggesting a role in the myelin compaction process. The shiverer mouse, a deletion mutant of the myelin basic protein (Mbp) gene, has poorly compacted myelin with essentially no MDL....
متن کاملPosttranslational Effects on Myelin Basic Protein in Transgenic Mice
Transgenic mice containing different numbers of transgenes (2–70) of the myelin proteolipid protein DM20 were phenotypically normal up to 3 mo of age, after which the mice containing 70 copies of the transgene spontaneously demyelinated and died at 10–12 mo. Since we demonstrated that demyelination in multiple sclerosis involved specific chemical changes in myelin basic protein (MBP), we invest...
متن کاملHuman umbilical cord blood-derived mesenchymal stem cells upregulate myelin basic protein in shiverer mice.
Human umbilical cord blood is a rich source of pluripotent mesenchymal stem cells and possesses significant advantages over other stem cell sources such as the embryo and bone marrow. In the present study, we aimed to investigate the potential of human umbilical cord blood-derived pluripotent mesenchymal stem cells (hUCB) to myelinate the axons of shiverer mice brains. We also investigated the ...
متن کاملMyelin basic protein.
The fact that central nerve tissue is encephalitogenic has been known since the observation of a post-injection reaction of some rabies victims to the Pasteur vaccine that contained nerve tissue (Brostoff, 1977). Subsequently the encephalitogenic agent in central nerve tissue was traced to a component of the myelin sheath, and a protein was finally isolated that in the presence of complete Freu...
متن کاملEnzymic methylation of myelin basic protein in myelin.
Myelin fractions with different degrees of compaction were isolated from bovine brain, and post-translational methylation of membrane-associated proteins was studied. When the purified myelin-basic-protein-specific protein methylase I and S-adenosyl-L-[methyl-14C]methionine were added exogenously, the most compact myelin fraction exhibited higher methyl-accepting activity than the less compact ...
