Transgenic mice containing different numbers of transgenes (2–70) of the myelin proteolipid protein DM20 were phenotypically normal up to 3 mo of age, after which the mice containing 70 copies of the transgene spontaneously demyelinated and died at 10–12 mo. Since we demonstrated that demyelination in multiple sclerosis involved specific chemical changes in myelin basic protein (MBP), we invest...
Objective(s) Erythropoietin has been shown to exert neuroprotective effects in a variety of CNS injury models. Elevation of serum S100β, as a glial damage marker and myelin basic protein (MBP) has been reported to occur in acute carbon monoxide (CO) poisoning. The aim of this study was to evaluate the effect of erythropoietin (EPO) on serum S100β and MBP levels after CO poisoning in rats. Mat...
Breakdown of myelin sheaths is a pathological hallmark of several autoimmune diseases of the nervous system. We employed autoantibody-mediated animal models of demyelinating diseases, including a rat model of neuromyelitis optica (NMO), to target myelin and found that myelin lamellae are broken down into vesicular structures at the innermost region of the myelin sheath. We demonstrated that mye...
Objective: DNAand myelin basic protein (MBP)-hydrolyzing antibodies can play an important role in the pathogenesis of systemic lupus erythematosus (SLE), therefore their analysis seems to be important. Results: In mammalians there are serine proteases, metalloproteases, and DNases. Each of these and many other enzymes catalyze only one chemical reaction. Very unusual and unpredictable situation...
OBJECTIVES Misfolding of key disease proteins to an insoluble state is associated with most neurodegenerative conditions, such as prion, Parkinson, and Alzheimer's diseases. In this work, and by studying animal models of multiple sclerosis, we asked whether this is also the case for myelin basic protein (MBP) in the late and neurodegenerative phases of demyelinating diseases. METHODS To this ...
We have identified a novel transcription unit of 105 kilobases (called the Golli-mbp gene) that encompasses the mouse myelin basic protein (MBP) gene. Three unique exons within this gene are alternatively spliced into MBP exons and introns to produce a family of MBP gene-related mRNAs that are under individual developmental regulation. These mRNAs are temporally expressed within cells of the ol...
In peripheral nerves, large caliber axons are ensheathed by myelin-elaborating Schwann cells. Multiple lines of evidence demonstrate that expression of the genes encoding myelin structural proteins occurs in Schwann cells in response to axonal instructions. To gain further insight into the mechanisms controlling myelin gene expression, we used reporter constructs in transgenic mice to search fo...
OBJECTIVE We investigated T cell responses to myelin proteins in the blood of healthy controls and 2 groups of patients with relapsing-remitting multiple sclerosis (RRMS) who exhibited lesions either predominantly in the brain or predominantly in the spinal cord in order to assess whether distinct neuroinflammatory patterns were associated with different myelin protein-specific T cell effector ...
Demyelination in the central nervous system is the hallmark feature in multiple sclerosis (MS). The mechanism resulting in destabilization of myelin is a complex multi-faceted process, part of which involves deimination of myelin basic protein (MBP). Deimination, the conversion of protein-bound arginine to citrulline, is mediated by the peptidylarginine deiminase (PAD) family of enzymes, of whi...
Experimental allergic encephalomyelitis is characterized by invasion of lymphocytes and macrophages into the central nervous system resulting in inflammation, edema, and demyelination. Sera from Lewis rats from 7-95 days after immunization with purified guinea pig CNS myelin were examined with respect to their ability to opsonize myelin. This was correlated with the appearance of antibody compo...
