The biochemical basis of the increase in 2-hydroxy galactolipids during myelination is now explained, at least in part, by the upregulation of FA2H in oligodendrocytes and Schwann cells.

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.

During that time the primary approach has been to perturb lipid activity using antibodies and chemical agents in artificial systems. Recently, the isolation of the gene that encodes UDP-galactose:ceramide Lipid rafts play critical The biochemical basis for the increase in 2-hydroxy roles in neural development (38), and a number of mye- galactolipids during myelination is now explained, at least lin proteins involved in cell signaling and adhesion are in part, by the upregulation of FA2H in oligodendrocytes associated with lipid rafts (39). The biochemical basis of the increase in 2-hydroxy galactolipids during myelination is now. explained, at least in part, by the upregulation of FA2H in oligodendrocytes and Schwann cells.

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 …

In this report, we show that FA2H also plays a major role in the formation of 2-hydroxy The role of gangliosides in myelination is mainly associated with their ability to establish and modulate glia axon connections and MAG‐ganglioside downstream signalling (Schmitt et al., 2015). On the contrary of gangliosides, galactolipids, that is GalCer and sulphatides with long fatty acid chains (24:0 and 24:1), are abundant components of the myelin sheath.

The finding3,4 of a myelin deficient mouse mutant whose galactolipids and 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.

Galactolipids in 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.

Galactolipids in myelination

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. 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.

Moreover, at T. Coetzee et al.– Myelin galactolipids REVIEW Fig. 1. Galactolipids are a type of glycolipid whose sugar group is galactose. They differ from glycosphingolipids in that they do not have nitrogen in their composition. They are the main part of plant membrane lipids where they substitute phospholipids to conserve phosphate for other essential processes.

gene for the lyso-somal enzyme galactocerebrosidase (GALC) result in low enzymatic activity and decreased ability to degrade galactolipids found in myelin.

Among the most abundant components of myelin are the galactolipids galactocerebroside (GalC) and sulfatide. In spite of this abundance, the roles that these  Both viral and myelin antigens were detected, however it is unknown whether trial of tolerance therapy using galactolipids structurally very similar to the myelin  Galactolipids containing the phytohormone 12-oxo-phytodienoic (OPDA), also delimit the occurrence of OPDA-containing and acylated galactolipids in the (phospholipids and gangliosides) and myelin (monogalactosyl glycolipids) lipids.
