(biochemistry)
One of a group of glycosphingolipids found in neuronal surface membranes and spleen; they contain an N-acyl fatty acid derivative of sphingosine linked to a carbohydrate (glucose or galactose); they also contain N-acetylglucosamine or N-acetylgalactosamine, and N-acetylneuraminic acid.

Director of the Parkinson's Disease Research Unit and Professor in the Department of Pathology, Anatomy and Cell Biology and the Department of Neurology at Jefferson, found that administration of GM1 ganglioside, a substance naturally enriched in the brain that may be diminished in Parkinson's disease brains, acted as a "neuroprotective" and a "neurorestorative" agent to improve symptoms and over an extended period of time slow the progression of symptoms.

Secondly, as discussed above, both CT and LT also bind with high affinity via their B-subunits to GM1 ganglioside receptors, which are present on most mammalian cells including not only epithelial cells, such as the "M cells" covering the Peyer's patches, but also all known antigen-presenting cells (APCs); this facilitates the uptake and presentation of the toxins to the gut mucosal immune system.
