Oligodendroglial Myelin Basic Protein (MBP) synthesis is essential for myelin formation in the central nervous system. During oligodendrocyte differentiation, MBP mRNA is kept in a translationally silenced state while intracellularly transported, until neuron-derived signals initiate localized MBP translation. Here we identify the small non-coding RNA 715 (sncRNA715) as an inhibitor of MBP tran...
Myelin basic protein (MBP) binds to negatively charged lipids on the cytosolic surface of oligodendrocyte membranes and is responsible for adhesion of these surfaces in the multilayered myelin sheath. The pattern of extensive posttranslational modifications of MBP is dynamic during normal central nervous system development and during myelin degeneration in multiple sclerosis (MS), affecting its...
myelin basic protein (mbp) is one of the most important constituents of the cns myelin sheaths. it is supposed that an autoimmune response directed against mbp is crucial in the demyelination process in patients with multiple sclerosis. studies have proved that free anti-mbp level in csf of ms patients is declined when the patient entered into clinical remission. some researchers evaluate the c...
Background: Progesterone as a sex steroid hormone is thought to affect and prevent demyelination, but its role in promoting myelin repair is far less investigated. In this study, remyelinating potential of progesterone in corpus callosum was evaluated on an experimental model of MS.Methods: In this experimental study, adult male C57BL/6 mice were fed with 0.2% (w/w) cuprizone in ground breeder ...
The cellular and subcellular distributions of mRNAs encoding three myelin-specific proteins--myelin basic protein (MBP), proteolipid protein (PLP), and Po protein--were studied in tissue sections of developing rat nervous systems by in situ hybridization. The developmental appearance of these mRNAs closely paralleled the appearance of the proteins they encode as determined by immunocytochemistr...
غلاف میلین اطراف آکسونها، دارای ساختار منحصر به فرد چند لایه ای است. (mbp) myelin basic proteinاز نظر فراوانی دومین پروتئین، بعد از پروتئولیپید پروتئین (plp) است. در سیستم عصبی مرکزی، mbp 30% از کل پروتئین ها و حدود 10% از میلین با وزن خشک را تشکیل می دهد. این تنها پروتئین ساختاری ضروری برای تشکیل میلین در cns است که تاکنون پیدا شده است. mbp پروتئینی چندکاره است که به واسطه میانکنش های متعدد با...
Multiple sclerosis (MS) is associated with breakdown of the myelin sheath that coats neurons in the central nervous system. The cause of MS is not known, although the pathogenesis involves destruction of myelin by the immune system. It was the aim of this study to examine the abundant myelin protein, myelin basic protein (MBP), to determine if there are sites of modification that may be charact...
Multiple sclerosis (MS) is an autoimmune disease in which the myelin sheath of the central nervous system is degraded, and the 18.5 kDa isoform of myelin basic protein (MBP) is reduced in cationicity. In a unique case of acute, fulminating MS (Marburg's variant), MBP is considerably less cationic than MBP from both normal, and chronic MS-afflicted individuals. This electron microscopical study ...
Fractions containing myelin of varying degrees of compaction were prepared from human white matter. Protein kinase activity in these fractions was measured by using both endogenous and exogenous myelin basic protein (MBP) as substrates. In both cases, less compact myelin fractions possessed higher levels of protein kinase activity than the compact myelin fraction. In addition, the specific acti...
Background: Multiple sclerosis (MS), as a multifactorial autoimmune disease with complex genetic basis, causes demyelination in the central nervous system via cytokine responses to myelin antigens. Myelin basic protein (MBP) is the main protein component of the myelin sheath. HLA-DRB (human leukocyte antigen-DR beta) alleles, particularly HLA-DRB1*1501, may be of significance in the pathogenesi...
