WebJan 6, 2024 · Background Gangliosides are glycosphingolipids highly enriched in the brain, with important roles in cell signaling, cell-to-cell communication, and immunomodulation. Genetic defects in the ganglioside biosynthetic pathway result in severe neurodegenerative diseases, while a partial decrease in the levels of specific gangliosides was reported in … Web4.1 Gangliosides as the key molecules for the assembly and function of lipid raft. Gangliosides in the cell membrane participate in various cell-surface interactions as ligands for biomolecules such as proteins and glycoconjugates. Cell-surface interactions can be divided into trans - and cis -interactions. Trans -interactions are interactions ...
