Oligodendroglia growth factor (OGF) is a 16-kDa soluble protein produced by neuronal cell lines. This factor, when incubated with brain glia in culture, selectively stimulates growth of oligodendroglia, the myelin-producing cells of the CNS. OGF infused into the cerebral cortex of the adult rat accelerates the production of myelin proteins as shown by increased specific activity of the myelin e...

Free and membrane-bound polyribosomes were isolated from the forebrain of actively myelinating 24-day-old rats. The poly(A)+ RNA (polyadenylated RNA) extracted from both fractions was translated in vitro in reticulocyte lysates [Hall & Lim (1981) Biochem. J. 196. 327-336] in the presence or absence of a heterologous microsomal membrane fraction from dog pancreas. The rat myelin basic proteins s...

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...

Developmental changes in protein composition of myelin obtained from whole brain of various species were the subject of several studies in recent years 1-3. By contrast, very little was been published on the composition of myelin proteins derived from forebrain 4 and from spinal cord 4~7. In relation to possible specific function of myelin in various regions of the central nervous system (CNS) ...

multiple sclerosis (ms) is an inflammatory disease of the central nervous system of presumed autoimmune etiology. one of the best animal models of demyelinating diseases is experimental autoimmune encephalomyelitis (eae), which can be induced in a variety of animals by injection of a target antigen such as myelin basic protein (mbp). the immune responses against the target amino acids cause tis...

A nonconservative leucine to proline mutation in peripheral myelin protein 22 (PMP22) causes the Trembler-J (TrJ) neuropathy in mice and humans. The expression levels and localization of the PMP22 protein in the TrJ mouse have not been previously determined. The aim of our studies was to reevaluate the extent of myelin deficit in genotyped heterozygous and homozygous animals and to examine how ...

Cover Illustration: Confocal image of a mature oligodendrocyte in vitro following the addition netrin-1, immuno-labelled for mitochondrial docking protein syntaphilin (red), outer membrane TOM20 (green), myelin basic (white), and Hoechst dye (blue). Syntaphilin is associated with mitochondria oligodendrocytes recruited to cell processes by netrin-1. (See Nakamura, DS, et al. https://doi.org/10....

Myelin basic protein has been isolated from bovine central-nervous-system myelin by four methods, none of which exposes the protein to acid. After purification the inositol content of both hydrolysed and unhydrolysed protein was quantified by g.c.-m.s. Basic protein prepared by all methods contained less than 4 mol % of inositol. It is concluded, contrary to a previous proposal, that covalent b...

Rapid conduction of nerve impulses requires coating of axons by myelin. To function as an electrical insulator, myelin is generated as a tightly packed, lipid-rich multilayered membrane sheath. Knowledge about the mechanisms that govern myelin membrane biogenesis is required to understand myelin disassembly as it occurs in diseases such as multiple sclerosis. Here, we show that myelin basic pro...
