●Gangliosides help stabilize the brain. Proia, R. L. Nature Genetics November (2004) Lysosomal storage diseases are caused by interference with the breakdown of gangliosides, which are glycolipids that are found in abundance in the brain. New work showing that abnormalities in the synthesis of gangliosides are responsible for an inherited form of epilepsy is described in this News and Views article.
