General description

Gangliosides are major constituents of neuronal cell membranes and endoplasmic reticulum; contain a sialated polysaccharide chain linked to ceramide through a β-glycosidic linkage; for classification of gangliosides see Svennerholm, L., et al. (eds.), Structure and Function of Gangliosides, New York, Plenum, 1980.

Biochem/physiol Actions

May act as a bacterial toxin receptor (tetanus, botulinus); high levels found in gliomas and astrocytomas.

Antiganglioside antibodies are found in various neurological disorders that constitute a continuum from peripheral neuropathy to encephalitis. However, nystagmus has rarely been described in patients with ataxia associated with antiganglioside antibodies. From January 2008 to July 2009, we identified 3

Gangliosides (GGs), a large group of sialylated glycosphingolipids, are considered biomarkers of human brain development, aging and certain diseases. Determination of individual GG components in complex mixtures extracted from a human brain represents a fundamental prerequisite for correlating their specificity

In spite of their low incidence, central nervous system tumors have elevated morbidity and mortality, being responsible for 2.3% of total cancer deaths. The ganglioside O-acetylated GD1b (O-Ac GD1b; neurostatin), present in the mammalian brain, and the semi-synthetic O-butyrylated GD1b

Immunization of rabbits with bovine brain gangliosides induced an experimental neuropathy, with clinical signs resembling Guillain-Barré syndrome. All the immunized animals developed immunoglobulin G immunoreactivity to GM1 ganglioside. In a few (4 of 27) animals, an additional anti-ganglioside antibody population

Clinical severity of Guillain-Barré syndrome (GBS) is highly variable, but the immunopathological reason is unknown. The study was designed to show which antibody parameters are associated with disease severity in GBS patients with serum anti-GM1 IgG antibodies. Thirty-four GBS patients
