GD2-Ganglioside , Disialoganglioside-GD2

GD2 (shown as sodium salt) has a core trisaccharide structure (GalNAc-b-1,4-Gal-b-1,4-Glc) with its two sialic acids linked b-2,3/b-2,8 to the inner galactose residue and ceramide linked to position 1 on the reducing terminal glucose residue. GD2 ganglioside is expressed at a low concentration in the central nervous system, nerves, skin melanocytes and stem cells in healthy adults. On the other hand, GD2 is overexpressed in a number of tumors, including: neuroblastoma, melanoma, small cell lung carcinoma and brain tumors. Recently, it has been found in low concentrations on breast cancer stem cells (CSC) that possess: self-renewal properties (division without disrupting the undifferentiated state), and tumor-initiating capabilities.  It has been suggested that GD2 ganglioside may be developed as an effective target antigen for CSC immunotherapy (Fleurence, 2017).

GD2 Ganglioside is a glycolipid that is found on the surface of cells and is involved in numerous biological functions. Gangliosides are complex lipids, composed of a hydrophobic tail and a hydrophilic head that is composed of a sialic acid residue and a complex sugar chain. GD2 Ganglioside is a unique glycolipid that is expressed on the surface of human neuroblastoma cells, melanoma cells, and small cell lung cancer cells. It has garnered a considerable amount of attention due to its potential use in various fields of research and industry.
