Myelination in the absence of galactolipids and proteolipid proteins. Coetzee T., Suzuki K., Nave K.A., Popko B. 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.

Here, we have generated To investigate further factors involved in regulating myelino‐genesis in these mice, we have focused on the synthesis of cerebrosides and sulfatides, galactolipids enriched in myelin. Brain slices from 14‐, 17‐, and 21‐day‐old D2, B6, and F., mice were incubated with [ 3 H]galactose and [ 35 S]sulfate. Approximately 70% of the dry weight of myelin is lipid, with the galactolipid galactocerebroside (GalC) and its sulfated derivative sulfatide encompassing about one-third of the lipid mass (reviewed by Norton and Cammer, 1984).

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. 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.

1984-11-01 These observations indicate that FA2H is a myelination-associated gene. FA2H-directed RNA interference (RNAi) by short-hairpin RNA expression resulted in a reduction of cellular 2-hydroxy fatty acids and 2-hydroxy GalCer in D6P2T Schwannoma cells, providing direct evidence that FA2H-dependent fatty acid 2-hydroxylation is required for the formation of 2-hydroxy galactolipids in peripheral The lateral membrane organization and dynamics of myelin proteins PLP and MBP are dictated by distinct galactolipids and the extracellular matrix.

A defining feature of the vertebrate nervous system is the ensheathment of axons by myelin, a multilamellar membrane containing a small group of proteins and an abundance of the galactolipid galactocerebroside (GalC) and its sulfated derivative sulfatide. Several in vitro studies have suggested that these galactolipids transduce developmental signals, facilitate protein trafficking and
