Gangliosides and autoimmune diabetes
Diabetes / Metabolism Reviews, 1997Gangliosides are sialic acid-containing glycolipids which are formed by a hydrophobic portion, the ceramide, and a hydrophilic part, i.e. the oligosaccharide chain. First described in neural tissue, several studies have shown that gangliosides are almost ubiquitous molecules expressed in all vertebrate tissues.

Lipid and glycolipid mediators are important messengers of the adaptive responses to stress, including apoptosis. In mammalian cells, the intracellular accumulation of ganglioside GD3, an acidic glycosphingolipid, contributes to mitochondrial damage, a crucial event during the apoptopic program. GD3 is a minor ganglioside in most normal tissues.

Gangliosides and Tumorigenesis
1981Glycolipids are molecules whose roles as membrane or cell surface receptors that might contribute to the regulation or control of tumorigenesis are just beginning to be understood. Glycolipid changes are consistent features of the complex patterns of glycoconjugate alterations contributing to cancer (Hakomori 1975; Richardson et al.

A ganglioside spin label: Ganglioside head group interactions
Biochemical and Biophysical Research Communications, 1977Abstract A general procedure has been developed for covalent attachment of a nitroxide spin label in the head group region of gangliosides. Gangliosides so labeled and incorporated into lipid bilayer vesicles give a sharp, 3-line spectrum characteristic of a highly mobile structure.

Gangliosides comprise a varied family of glycosphingolipid structures bearing one or more sialic acid residues. They are found in all mammalian tissues but are most abundant in the brain, where they represent the quantitatively major class of sialoglycans.

Biochemistry, 1984
Ultraviolet difference absorption spectra of cholera toxin and its B protomer produced by the oligosaccharide moiety of the monosialoganglioside GM1 were measured as a function of the oligosaccharide concentration. In the presence of oligosaccharide, the spectrum is characterized by three peaks at 282, 288, and 292 nm.

GANGLIOSIDES IN THE NERVOUS SYSTEM
Neurochemistry International, 1983Gangliosides, sialic acid-containing glycosphingolipids, are embedded in neural plasma membranes to provide cell surface recognition sites with negative charges. Exogenous ligands such as bacterial toxins, hormones, growth factors, antibodies, viruses, and interferons bind to specific gangliosides to induce sequential activations of cellular ...

On the loss of gangliosides by dialysis
Journal of Neurochemistry, 1973The Gangliosides represent a family of sialic acidcontaining sphingoglycolipids which have ceramide (N‐acyl‐sphingosine) as the basic hydrophobic portion (Svennerholm, 1972). A heteropolysaccharide is glycosidically linked through the primary hydroxyl group of ceramide and the aldehyde of glucose. There are usually three or four different carbohydrates

Anti-ganglioside antibodies react with carbohydrate epitopes borne by a large family of glycosphingolipids that are highly enriched in the nervous system. Antibodies to over 20 different gangliosides and related glycolipids have now been associated with a wide range of clinically identifiable acute and chronic neuropathy syndromes.

Gangliosides and Cell Surface Ganglioside Glycohydrolases in the Nervous System
2014Gangliosides are a large group of complex lipids found predominantly on the outer layer of the plasma membranes of cells, and they are particularly concentrated in nerve endings. Their half-life in the nervous system is short, and their membrane composition and content are strictly connected to their metabolism.
