ganglioside. [ gang´gle-o-sīd] a class of galactose-containing cerebrosides found in central nervous system tissues; they are glycolipids of the basic composition ceramide-glucose-galactose-N-acetyl neuraminic acid. The form GM 1 accumulates in tissues in generalized gangliosidosis, the form GM 2 in Tay-Sachs disease Gangliosides are sialic acid-containing glycosphingolipids. They occur especially on the cellular surfaces of neuronal cells, where they form a complex pattern, but are also found in many other cell types. The paper provides a general overview on their structures, occurrence, and metabolism. Key functional, biochemical, and pathobiochemical aspects are summarized

Ganglioside - an overview ScienceDirect Topic

Gangliosides are major nerve cell surface molecular determinants throughout the central and peripheral nervous systems, and major brain ganglioside structures have been well preserved throughout mammalian and avian evolution.1 The discovery of human CDGg establish the importance of gangliosides in brain development, motor and sensory function, cognition and axon-myelin stability Gangliosides are glycosphingolipids highly abundant in the nervous system, and carry most of the sialic acid residues in the brain. Gangliosides are enriched in cell membrane microdomains (lipid rafts) and play important roles in the modulation of membrane proteins and ion channels, in cell signaling and in the communication among cells Glycosphingolipids (sialic acid containing) A family of complex amphiphatic molecules, consisting of a carbohydrate and a lipid portion. The carbohydrate portion is comprised of one or more sialic.. Gangliosides are essential components of cell membranes and are involved in a variety of physiological processes, including cell growth, differentiation, and receptor-mediated signal transduction. They regulate functions of proteins in membrane microdomains, notably receptor tyrosine kinases such as insulin receptor (InsR) and epidermal growth factor receptor (EGFR), through lateral association 1.

Gangliosides and cancer therapy: This review summarizes the current knowledge on the structure and biosynthesis of gangliosides. Progress in mass spectrometry analysis of gangliosides means that their role in cancer progression can be now investigated in more detail and this is also discussed, together with the recent development of cancer immunotherapy targeting gangliosides Gangliosides. Gangliosides are acidic glycosphingolipids that contribute a substantial presence to the outer leaflet of the cell plasma membrane. This is especially apparent in neuronal cells of the central nervous system where they have vital roles as neurotransmitters and cellular regulators. 1 They participate in cellular proliferation,.

distribution of individual gangliosides in VLDL and LDL was almost the same as that in the unfractionated serum; some differences existed with the ganglioside profile in HDL.

Published by Houghton Mifflin Company Gangliosides activated extracellular signal-regulated kinase significantly but activated c-junN-terminal kinase/stress-activated protein kinase and p38 relatively weakly. The inhibition of extracellular signal-regulated kinase by PD98059 reduced NO release from both gangliosides- and GT1b-treated microglia whereas inhibition of p38 by SB203580 increased it rather slightly Using these gangliosides and mutated forms of HCR/T that lacked one or both carbohydrate-binding pocket, gangliosides binding to both of the W and R pockets were shown to be necessary for high affinity binding to neuronal and non-neuronal cells

The effects of simulated gastrointestinal digestion upon sialic acid and gangliosides in infant and follow-on formulas and human milk, as well as their bioaccessibility, have been evaluated. The gastric stage is the step that causes a greater decrease in sialic acid and ganglioside contents. The intestinal stage only decreases the total and individual contents of gangliosides GM1 gangliosidosis is an inherited lysosomal storage disorder that progressively destroys nerve cells (neurons) in the brain and spinal cord. The condition may be classified into three major types based on the general age that signs and symptoms first appear: classic infantile (); juvenile (); and adult onset or chronic ().Although the types differ in severity, their features may overlap.
