Stereochemical structures of synthesized and natural plasmalogalactosylceramides from equine brain

Journal of Lipid Research, 1998
Modified galactosylceramide with a long-chain cyclic acetal at the sugar moiety, plasmalogalactosylceramide, was isolated from equine brain. To identify the isomeric stereostructure of the natural product, the plasmalo derivative was chemically ...

FA2H-dependent fatty acid 2-hydroxylation in postnatal mouse brain

Journal of Lipid Research, 2006
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.

Quantitative analysis of brain galactosylceramides by high performance liquid chromatography of their perbenzoyl derivatives

Journal of Lipid Research, 1976
A high performance liquid chromatographic (HPLC) method for analysis of galactosylceramides as their benzoyl derivatives has been devised. Samples containing 10-150 nmoles of monohexosylceramides are benzoylated by heating for 60 min at 60 ° C in 0.5 ml ...

Reduced chain length in myelin sphingolipids and poorer motor coordination in mice deficient in the fatty acid elongase Elovl1

FASEB BioAdvances, 2019
Very‐long‐chain fatty acids, with a chain length of >C20, are abundant in myelin sphingolipids. Recently, a de novo mutation in the ELOVL1 gene, which encodes fatty acid elongase, was identified in patients with neurocutaneous disorders involving skin ...

Neutral glycosphingolipids in human blood: a precise mass spectrometry analysis with special reference to lipoprotein-associated Shiga toxin receptors[S]

Journal of Lipid Research, 2010
Shiga toxin (Stx)-producing Escherichia coli are the leading cause of hemorrhagic colitis and life-threatening extraintestinal complications in humans. Stx1 and Stx2 are transferred by yet to be delineated mechanisms from the intestine to the circulation

C-galactosylceramide: Synthesis and immunology [PDF]

Comptes Rendus. Chimie, 2011
A synthetic C-glycoside, α-C-galactosylceramide, is an active immunostimulant in mice. It displays better activity than α-O-galactosylceramide in several disease models. Syntheses of several α-C-galactosylceramides are described. Experiments that probe its immunostimulant activity are outlined.

Prophylaxis of lipopolysaccharide-induced shock by α-galactosylceramide [PDF]

Journal of Leukocyte Biology, 2008
AbstractThe NKT cell ligand α-galactosylceramide and its synthetic homologue KRN7000 stimulate rapid and copious secretion of IFN-γ and TNF-α release, both of which are key mediators of LPS-induced shock. We showed that KRN7000, injected before or within 2 h after LPS challenge, was able to prevent endotoxic shock.

Unraveling A4GALT Mechanism and Its Modulation With Adamantyl‐Galactosylceramide Analogues: Advancing Fabry Disease Therapeutic Strategies

Angewandte Chemie, EarlyView.
A 310‐helix‐mediated conformational switch promotes a front‐face SNi‐like catalysis by human A4GALT. Mechanism‐guided design identifies AdaGalCer as a selective modulator of globotriaosylceramide (Gb3) biosynthesis, opening a clear route toward new Fabry disease therapeutics.

Functional invariant natural killer T-cell and CD1d axis in chronic lymphocytic leukemia: implications for immunotherapy

Haematologica, 2013
Invariant natural killer T cells recognize glycolipid antigens such as α-galactosylceramide presented by CD1d. In preclinical models of B-cell malignancies, α-galactosylceramide is an adjuvant to tumor vaccination, enhancing tumor-specific T-cell ...

Simultaneous quantification of lyso-neutral glycosphingolipids and neutral glycosphingolipids by N-acetylation with [3H]acetic anhydride

Journal of Lipid Research, 2003
We describe a new method that permits quantification in the pmol to nmol range of three lyso-neutral glycosphingolipids (lyso-n-GSLs), glucosylsphingosine (GlcSph), galactosylsphingosine (GalSph), and lactosylsphingosine, in the same sample as neutral ...
