AU - Poretz, R. D. PY - 2001/4/15. Y1 - 2001/4/15. N2 - Lead poisoning is known to cause myelin defects. Galactolipids are the major lipid components of myelin and myelin-competent oligodendrocytes.

The multiplicity of functions performed by the myelin proteins and galactolipids indicates that the remarkable structure and function of myelin results from the combined contributions of its individual components. 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.

After incubation, microsomes, myelin, and oligodendroglial cells were isolated, and the galactolipids were analyzed. Consequently, in relation to prenatal levels galactolipids increased most rapidly in the cerebrum, followed by the cerebellum and finally by the brain stem.

Galactolipids brain

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. 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. The galactolipids have a range of important functions required for establishment of functional myelin and thus, they must be added to the expanding list of essential components of the myelin sheath. The multiplicity of functions performed by the myelin proteins and galactolipids indicates that the remarkable structure and function of myelin results from the combined contributions of its individual components.

Galactolipids brain

2-Hydroxy fatty acids are relatively minor species of membrane lipids found almost exclusively as N-acyl chains of sphingolipids. In mammals, 2-hydroxy sphingolipids are uniquely abundant in myelin galactosylceramide and sulfatide. Despite the wel In contrast, brain weight was slightly increased by RJ administration but not by E2 administration. The contents of protein and myelin galactolipids were higher in the brains of RJ-administered OVX rats than in the brains of E2-administered OVX rats. Phospholipid, cholesterol, and galactolipid are major composition of brain (Calderon et al., 1995; Van Meer et al., 2008), whereas phosphatidylinositol (3,4,5)-trisphosphate (PIP3) and diacylglycerol are well known as lipid second messengers (Ohanian and Ohanian, 2001).

Groups of brains from rats of various ages–7 to 275 days–were analyzed for their contents of galactolipids (cerebroside + cerebroside sulfate), cholesterol, and the individual fatty acids of The galactolipids galactocerebroside and sulfatide and the proteolipid protein which can be synthesized only by sulfation of galactosylceramide, is also totally absent in affected mouse brain. We found: (1) a significantly higher (104%; P<0.01) content of brain myelin galactolipids in the high-Al3+ group than in controls, and, (2) a significant correlation (r2=0.70; P<0.01) between the concentration of myelin galactolipids and TBARS (2-thiobarbituric acid-reactive substances) content, a parameter of lipid oxidation.

Abstract— The incorporation in vivo of [U‐14C]glucose into the galactolipids of the brain of control and Jimpy mutant mice was examined. Over a 24‐h period of incorporation there was no indication of an increased rate of turnover of brain galactolipids in the mutant. The Jimpy mutant was identified at ages prior to and at the inception of myelination (7–10 days post partum) with a coat Our observations that NDK/Nm23A and B levels were reduced in CGT null and elevated in the same myelin compartment in CST null mice, without any alterations in the whole brain homogeates, led us to speculate that a lack of galactolipids may result in the dysregulation of the transport of NDK/Nm23 into the myelin compartment and that this is regulated differently in the two mutants. 1976-07-01 Brain concentrations of galactolipids, and the cellular activity of galactolipid metabolic enzymes are reduced in rat pups exposed to Pb in utero, subsequently through maternal milk from exposed Myelin Galactolipids Are Essential for Proper Node of Ranvier Formation in the CNS Jeffrey L.

Consequently, it is not surprising that in the rat all the regions, and not only the cerebrum, have been shown to be vulnera- The precise alignment of myelin segments along the length of the axon is essential for the saltatory propagation of an electrical impulse.
