Multiple sclerosis (MS) is a demyelinating disease of presumed T cell autoimmunity against self myelin. We hypothesized that if myelin-reactive T cells are associated with the disease processes, they may undergo activation and expansion during acute exacerbation. In this study, we examined the precursor frequency, epitope recognition and cytokine profile of myelin-reactive T cells in 14 relapsi...
Adhesive properties of proteolipid protein are responsible for the compaction of CNS myelin sheaths.
We have studied the molecular function of proteolipid protein (PLP), the main integral membrane protein of CNS myelin, by generating mice lacking PLP expression. Here, we demonstrate that these PLP-minus mice show no pleiotropism as mice carrying point mutations within the PLP gene. The expression of other myelin genes (myelin basic protein, MBP; myelin associated glycoprotein, MAG; UDP-galacto...
The 18.5 kDa isoform of myelin basic protein (MBP) is a major component of the myelin sheath in the central nervous system of higher vertebrates, and a member of a larger family of proteins with a multiplicity of forms and post-translational modifications (PTMs). The 18.5 kDa protein is the exemplar of the family, being most abundant in adult myelin, and thus the most-studied. It is peripherall...
Myelin is synthesized about the time of birth. The Src-family tyrosine kinase Fyn is involved in the initial events of myelination. Fyn is present in myelin-forming cells and is activated through stimulation of cell surface receptors such as large myelin-associated glycoprotein (L-MAG). Here we show that Fyn stimulates transcription of the myelin basic protein (MBP) gene for myelination. MBP is...
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...
Multiple sclerosis (MS) is an autoimmune chronic inflammatory disease of the central nervous system (CNS). Cross-reactivity of neuronal proteins with exogenous antigens is considered one of the possible mechanisms of MS triggering. Previously, we showed that monoclonal myelin basic protein (MBP)-specific antibodies from MS patients cross-react with Epstein-Barr virus (EBV) latent membrane prote...
Antibodies against myelin oligodendrocyte antigens have been found in the immunoreactive brain lesions of Multiple Sclerosis (MS) patients. Recently it has been proposed that these antibodies can be used as a prognostic marker in the course of disease. However, the serum levels of these autoantibodies during different phases of disease activity or after an immunomodulatory therapy have been poo...
The classic myelin basic protein (MBP) splice isoforms range in nominal molecular mass from 14 to 21.5 kDa, and arise from the gene in the oligodendrocyte lineage (Golli) in maturing oligodendrocytes. The 18.5-kDa isoform that predominates in adult myelin adheres the cytosolic surfaces of oligodendrocyte membranes together, and forms a two-dimensional molecular sieve restricting protein diffusi...
In the developing nervous system, abundant synthesis of myelin basic protein (MBP) in oligodendrocytes is required for the formation of compact myelin sheaths around axons. The MBP mRNA is known to be transported into the processes of oligodendrocytes. However, knowledge of the regulatory mechanisms that ensure the tight temporal and spatial control of MBP translation within these processes is ...
