Neuromuscular synaptic function in mice lacking major subsets of gangliosides [PDF]

, 2008
Gangliosides are a family of sialylated glycosphingolipids enriched in the outer leaflet of neuronal membranes, in particular at synapses. Therefore, they have been hypothesized to play a functional role in synaptic transmission.
