Rapid and Specific Immunomagnetic Isolation of Mouse

Aug 29, 1970 The finding3,4 of a myelin deficient mouse mutant whose galactolipids and sphingomyelin lack long chain fatty acids led us to investigate Jan 2, 2011 FA2H and other enzymes are responsible for the increase in 2-OH very-long- chain (>C20) fatty acid contents in galactolipids during myelination. Jan 23, 2008 The concentrations of phospholipids and galactolipids and their fatty acid compositions were determined in purified myelin from apparently Oct 1, 2009 Subsequent reactions produce ceramide, the precursor for galactolipids, gangliosides, and sphingomyelin (FIGURE 1). The enzyme Among the most abundant components of myelin are the galactolipids galactocerebroside (GalC) and sulfatide. In spite of this abundance, the roles that these Myelin is enriched in galactolipids and cholesterol and contains myelin-specific proteins, the major ones of which are myelin basic protein (MBP) and proteolipid Dynamics of Myelin Proteins PLP and MBP are Dictated by Distinct Galactolipids and the. Extracellular Matrix. Hande Ozgen1, Waldemar Schrimpf2, Jelle 2-hydroxygalactolipids account for as much as 60% of the myelin sheath, galactolipids in peripheral nervous system myelin” Journal of Lipid Research, vol. This dense network of hydrogen bonds is believed to contribute to the high transition temperature and the compact alignment of the galactolipids.

2002-12-19 · The galactolipids also appear to facilitate the maturation of both oligodendrocytes and myelinated fibers, suggesting that they process developmental signals during myelination. These specialized glycolipids are also necessary for the normal development of axo–glial interactions at nodes of Ranvier. The abnormal myelin structures present in the mutant animals are consistent with the possibility that the galactolipids play a role in regulating or mediating proper axo-glial interactions. The further detailed analysis of these animals should help refine our understanding of galactolipid function in the myelination process. Myelin in the mammalian nervous system has a high concentration of galactolipids [galactosylceramide (GalCer) and sulfatide] with 2-hydroxy fatty acids. We recently reported that fatty acid 2-hydroxylase (FA2H), encoded by the FA2H gene, is the major fatty acid 2-hydroxylase in the mouse brain. In this report, we show that FA2H also plays a major Myelin in the mammalian nervous system has a high concentration of galactolipids [galactosylceramide (GalCer) and sulfatide] with 2-hydroxy fatty acids.

Myelination is a developmentally regulated process whereby myelinating glial cells elaborate large quantities of a specialized plasma membrane that ensheaths axons. The myelin sheath contains an unusual lipid composition in that the glycolipid galactosylceramide (GalC) and its sulfated form sulfatide constitute a large proportion of the total lipid mass.

Although these studies suggest a role for GalC in axoglial interactions, the nature of these interactions remains to be determined. Moreover, at T. Coetzee et al.– Myelin galactolipids REVIEW Fig. 1.

Mol … bodies raised against GalC inhibit myelination in vitro and in vivo31–34. Although these studies suggest a role for GalC in axoglial interactions, the nature of these interactions remains to be determined. Moreover, at T. Coetzee et al.– Myelin galactolipids REVIEW Fig. 1. Despite the extraordinary abundance of 2-OH galactolipids in myelin, there is surprisingly little understanding of the basic biochemistry and physiological role of 2-OH galactolipids.

The galactolipids galactocerebroside and sulfatide and the proteolipid protein (PLP) and its splice variant DM20 are the most abundant lipid and protein components of central nervous system myelin. Recent studies have found that mice lacking either the galactolipids or PLP are able to form myelin sheaths with apparently normal periodicity and near normal compaction.

The precise alignment of myelin segments along the length of the axon is essential for the saltatory propagation of an electrical impulse. Furthermore, node of Ranvier formation and function are depe The myelin membrane is unique in that 70% of its dry weight consists of lipids, including cholesterol and galactolipids in particular, and it contains a specific set of proteins including proteolipid protein (PLP) and myelin basic protein (MBP). After normal myelination in utero, myelination of the neonatal brain is far from complete.

Despite the extraordinary abundance of 2-OH galactolipids in myelin, there is surprisingly little understanding of the basic biochemistry and physiological role of 2-OH galactolipids. The overall goal of this study is to elucidate the pathway for myelin 2-OH lipids and their roles in myelination, myelin function, and cell signaling. 2013-08-30 CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We have analyzed mice that lack both the myelinassociated glycoprotein (MAG) and the myelin galactolipids, two glial components implicated in mediating axo-glial interactions during the myelination process.
