Ganglioside GM1 is widely used in neuroscience research due to its role in neuronal function and development. It is a key component of cell membranes in the brain, particularly in lipid rafts, where it influences signal transduction and cell communication. GM1 is studied for its potential therapeutic applications in neurodegenerative diseases like Parkinson's and Alzheimer's, as it promotes neuronal survival and repair. Additionally, it is used in studies exploring its ability to bind toxins, such as cholera toxin, making it valuable in immunology and vaccine research. GM1 also plays a role in understanding cellular mechanisms related to cancer and autoimmune disorders.
