Myelin basic protein (MBP) is a protein believed [weasel words] to be important in the process of myelination of nerves in the nervous system. The myelin sheath is a multi-layered membrane, unique to the nervous system, that functions as an insulator to greatly increase the velocity of axonal impulse conduction . [ 5 ]
In terms of total mass, myelin comprises approximately 40% water; the dry mass comprises between 60% and 75% lipid and between 15% and 25% protein. Protein content includes myelin basic protein (MBP), [21] which is abundant in the CNS where it plays a critical, non-redundant role in formation of compact myelin; myelin oligodendrocyte ...
The insulation must be proportional to the diameter of the fibre inside. The optimal ratio of axon diameter divided by the total fiber diameter (which includes the myelin) is 0.6. [24] Oligodendrocytes in rat cerebellum stained with antibody to myelin basic protein in red and for DNA in blue. Two oligodendrocyte cell bodies are clearly visible ...
Myelin basic protein is the antigen in the myelin sheaths of the neurons that stimulates an autoimmune reaction in people with MS, so the peptide may work as a decoy for the attacking immune cells. Glatiramer acetate was originally discovered at the Weizmann Institute of Science. It is on the World Health Organization's List of Essential ...
It also seems that myelin basic protein (MBP) from multiple sclerosis (MS) patients contains lower levels of phosphorylation at Thr97 than normal individuals. [152] NAWM is the place where lesions appear and the process seems to be made by microglia, in absence of leukocyte infiltration, astrogliosis or demyelination.
Mature oligodendrocyte: After myelinogenesis, mature oligodendrocytes surround axons in organized, multilamellar myelin sheaths that contain myelin basic protein (MBP) and myelin proteolipid protein (PLP). Myelinogenesis thus encompasses the process of transition between phases 3 and 4. [6]
The experiment showed that after a partial crush injury of the optic nerve, rats injected with activated T cells which are specific for myelin basic protein (MBP, a common protein in the CNS) retained 3-fold more retinal ganglion cells with functionally intact axons than did rats injected with activated T cells specific for other (control ...
In enzymology, a [myelin basic protein]-arginine N-methyltransferase (EC 2.1.1.126) is an enzyme that catalyzes the chemical reaction S-adenosyl-L-methionine + [myelin basic protein]-arginine ⇌ {\displaystyle \rightleftharpoons } S-adenosyl-L-homocysteine + [myelin basic protein]-Nomega-methyl-arginine
