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.

In this study, we have tested for the possibility that MAG and myelin galactolipids function similarly in mediating early stages of myelination. Previous experiments, mainly cell culture based, have employed biochemical strategies to determine that MAG and the galactolipids are critical early mediators of myelin formation ( Dupree et al., 1998c ; Schachner and Bartsch, 2000 ). Martínez M. The developmental lipid profiles in the human cerebrum, cerebellum and brain stem are presented, with special reference to galactolipids as myelin markers to trace myelination in the three main parts of the human CNS. A group of undernourished children were also studied to test the vulnerability of myelinogenesis in the different 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.

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 role in the formation of 2-hydroxy galactolipids in the peripheral nervous system.

Similar that 72% of the minor galactolipids. (a class in which monogalactosyl diglyceride would belong) of brain were in myelin.

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 galactolipids galactocerebroside and sulfatide, which require the enzyme UDP-galactose:ceramide galactosyltransferase (CGT) for their synthesis, are among the most prevalent molecules in the myelin sheath. Numerous studies, mainly using antibody perturbation methods in vitro, have suggested that … Not only do myelin galactolipids occur abundantly on the extracellular surface of myelinating membranes, but GalC and sulfatide are also expressed very early in the differentiation process , , .

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.

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 …
