[Interaction of gangliosides with serotonin].
It has been shown that ganglioside micellae were able to reversible interaction with serotonin; the interaction is determined by their composition. Ganglioside and ganglioside-serotonin micellae were equal in sizes if pH, the ionic strength and the type of the buffer, the temperature and serotonin concentration were given. When the ganglioside micellae were saturated with serotonin the micallae became able to jumping reconstruction forming the structure able to bind more serotonin than the first one. As the serotonin concentration was increased CCM of mixed serotonin-ganglioside micellae was reached. It has been suggested that the reconstruction of the ganglioside micelle due to its interaction with serotonin can be considered as a model of a cooperative transfer of the postsynaptical membrane when a nervous impulse passes through a synapse.
