With aging, our brains become more susceptible to disease and injury. Different regions of the brain have differing levels of vulnerability to stress and injury, and this brain region-dependent variability to vulnerability could be partly explained by the existence of glycosphingolipids within the cell’s plasma membrane called gangliosides. Gangliosides are expressed predominantly within the brain and play various roles within the central nervous system including neural repair, cell survival, and neurodegeneration. Our laboratory has demonstrated that gangliosides can shift their composition from GM1 back to GM2 and GM3 following stroke in mice and rats indicating a role for simple gangliosides …
