basic protein molecule. The N-terminal portion of the polypeptide chain favours hydrophobic interactions with lipid (London et al., 1973; London & Vossenberg, 1973), whereas ionic interactions with lipid occur a t the C-terminal region (Jones & Rumsby, 1977). These structural features are considered to be important in maintaining the cytoplasmic apposition in myelin. The basic protein interacts...

background: the cuprizone multiple sclerosis (ms) animal model is characteristic for toxic demyelination and represents a reversible demyelination and remyelination system. it has been shown that green tea epigallocatechin-3-gallate (egcg) might be effective in improving the symptoms and pathological conditions associated with autoimmune inflammatory diseases in several animal models. objective...

BACKGROUND Multiple sclerosis is a human autoimmunological disease that causes neurodegeneration. One of the potential ways to stop its development is induction of oral tolerance, whose effect lies in decreasing immune response to the fed antigen. It was shown in animal models that administration of specific epitopes of the three main myelin proteins - myelin oligodendrocyte glycoprotein (MOG),...

A role for CD4(+)CD25(+) regulatory T cells (Tregs) in the control of allergic diseases has been postulated. We developed a mouse model in which anaphylaxis is induced in SJL mice by immunization and challenge with the fragment of self myelin proteolipid protein (PLP)(139-151), that is not expressed in the thymus, but not with fragment 178-191 of the same protein, that is expressed in the thymu...

Female B10.S mice are highly resistant to proteolipid protein (PLP) 139-151-induced experimental autoimmune encephalomyelitis (EAE) and depletion of PLP 139-151-reactive CD4+CD25+ regulatory T (Treg) cells can slightly increase their EAE susceptibility. Although male B10.S mice are moderately susceptible to EAE, we report that depletion of Treg cells in male B10.S mice before immunization with ...

The vulnerability of oligodendrocytes after cerebral ischemia still remains unclear. The purpose of this study was to clarify the response of oligodendrocytes in the hippocampus after transient global ischemia. Bilateral common carotid artery BCCA occlusion for 5 min was carried out in gerbils and brain sections obtained from gerbils 4 days, 2 weeks and 2 months after BCCA occlusion were used t...

rMAL, the rat myelin and lymphocyte protein, is a small hydrophobic protein of 17 kDa with four putative transmembrane domains and is expressed in oligodendrocytes and Schwann cells, the myelinating cells of the nervous system. In addition, transcript expression has been found in kidney, spleen, and intestine. Confocal microscopy and immunoelectron microscopy with an affinity-purified antibody ...

Mutations in the gene for proteolipid protein (PLP) have been associated with CNS dysmyelination and abnormal oligodendrocyte death in spontaneous mouse mutants and in Pelizaeus-Merzbacher disease; however, the effect of mutations on PLP structure and function are little understood. We have identified a monoclonal antibody directed against a novel cell surface epitope of PLP, termed O10. By imm...

Background: The cuprizone multiple sclerosis (MS) animal model is characteristic for toxic demyelination and represents a reversible demyelination and remyelination system. It has been shown that green tea epigallocatechin-3-gallate (EGCG) might be effective in improving the symptoms and pathological conditions associated with autoimmune inflammatory diseases in several animal models.
