multiple sclerosis (ms) is an autoimmune disease in which auto-reactive t cells react with self-antigens expressed in the central nervous system (cns). the main cause of ms is unknown. nonetheless, the most probable theory is based on molecular mimicry, which suggests that some infections can activate t cells against brain auto-antigens like myelin proteolipid protein (plp) and initiate the dis...

conclusions molecular assays in the early stages of the disease could help in elucidating the effectiveness of the mbp as a prognostic factor in ms. methods this study is convergence of three arms including in silico and in vitro (bioinformatics) with the in vivo (experimental). a novel methodology combining molecular techniques was used to confirm the antigenic properties of mbp and study its ...

OBJECTIVE Intrathecal IgG synthesis, persistence of bands of oligoclonal IgG, and memory B-cell clonal expansion are well-characterized features of the humoral response in multiple sclerosis (MS). Nevertheless, the target antigen of this response remains enigmatic. METHODS We produced 53 different human IgG1 monoclonal recombinant antibodies (rAbs) by coexpressing paired heavy- and light-chai...

It has become clear that the products of several of the earliest identified myelin protein genes perform functions that extend beyond the myelin sheath. Interestingly, these myelin proteins, which comprise proteolipid protein, 2',3'-cyclic nucleotide 3'-phosphodiesterase and the classic and golli MBPs (myelin basic proteins), play important roles during different stages of oligodendroglial deve...

After incomplete traumatic spinal cord injury (SCI), the spared tissue exhibits abnormal myelination that is associated with reduced or blocked axonal conductance. To examine the molecular basis of the abnormal myelination, we used a standardized rat model of incomplete SCI and compared normal uninjured tissue with that after contusion injury. We evaluated expression of mRNA for myelin proteins...

1. A myelin-like membrane fraction was isolated from developing rat brain by a new method. 2. The chemical composition and morphology of the fraction are described. 3. The myelin-like fraction is similar to myelin in characteristic enzyme activity but differs in the absence of basic protein and cerebrosides. No similarity to other subcellular fractions was observed. 4. It is suggested that the ...

The myelin sheath is a multilamellar plasma membrane extension of highly specialized glial cells laid down in regularly spaced segments along axons. Recent studies indicate that myelin is metabolically active and capable of communicating with the underlying axon. To be functionally connected to the neuron, oligodendrocytes maintain non-compacted myelin as cytoplasmic nanochannels. Here, we used...

Multiple sclerosis and migraine with aura are clinically correlated and both show imaging changes suggestive of myelin disruption. Furthermore, cortical myelin loss in the cuprizone animal model of multiple sclerosis enhances susceptibility to spreading depression, the likely underlying cause of migraine with aura. Since multiple sclerosis pathology involves inflammatory T cell lymphocyte produ...
