The central nervous system (CNS) insults may cause massive demyelination and lead to the release of myelin-associated proteins including its major component myelin basic protein (MBP). MBP is reported to induce glial activation but its effect on neurons is still little known. Here we found that MBP specifically bound to the extracellular surface of the neuronal plasma membrane and induced neuro...
Tumor overexpressed gene (TOG) protein, encoded by cytoskeleton-associated protein CKAP5, is a microtubule-associated protein that binds to heterogeneous nuclear ribonucleoprotein (hnRNP) A2. hnRNP A2 is an RNA trafficking factor that associates with myelin basic protein (MBP) mRNA. In oligodendrocytes, TOG, hnRNP A2, and MBP mRNA colocalize in granules that assemble in the perikaryon and are t...
76100 Rehovot Myelin-Reactive T Cells Are Present in Normal Israel Blood; Once Activated They May Penetrate †Department of Neurology and Neurological Sciences the Blood–Brain Barrier Beckman Center for Molecular and Genetic Medicine T cells reactive to the major constituents of the myelin Stanford University School of Medicine sheath, such as myelin basic protein (MBP) and proteoStanford, Calif...
The insulating layers of myelin membrane wrapped around axons by oligodendrocytes are essential for the rapid conduction of nerve impulses in the central nervous system. To fulfill this function as an electrical insulator, myelin requires a unique lipid and protein composition. Here we show that oligodendrocytes employ a barrier that functions as a physical filter to generate the lipid-rich mye...
The amounts of NG-methylarginine derivatives in myelin basic protein (MBP) purified from dysmyelinating mutant and different stages of normal myelinating mouse brains have been studied by using h.p.l.c. with a highly sensitive post-column o-phthaldialdehyde derivative-formation method. All three naturally occurring derivatives (NG-monomethylarginine (MeArg), NGN'G-dimethylarginine [Me2(sym)Arg]...
This unit details the materials and methods required for both active induction and adoptive transfer of experimental autoimmune encephalomyelitis (EAE) in the SJL mouse strain using intact proteins or peptides from the two major myelin proteins: proteolipid protein (PLP) and myelin basic protein (MBP). Detailed materials and methods required for the purification of both PLP and MBP are also des...
Force-distance measurements between supported lipid bilayers mimicking the cytoplasmic surface of myelin at various surface coverages of myelin basic protein (MBP) indicate that maximum adhesion and minimum cytoplasmic spacing occur when each negative lipid in the membrane can bind to a positive arginine or lysine group on MBP. At the optimal lipid/protein ratio, additional attractive forces ar...
Myelination in the central nervous system provides a unique example of how cells establish asymmetry. The myelinating cell, the oligodendrocyte, extends processes to and wraps multiple axons of different diameter, keeping the number of wraps proportional to the axon diameter. Local regulation of protein synthesis represents one mechanism used to control the different requirements for myelin she...
Our understanding of myelination has been greatly enhanced via the study of spontaneous mutants that harbor a defect in a gene encoding one of the major myelin proteins (myelin mutants). In this study, we describe a unique genetic defect in a new myelin mutant called the Long Evans shaker (les) rat that causes severe dysmyelination of the CNS. Myelin deficits result from disruption of the myeli...
