    Abstract:
    To investigate effects of gangliosides on nerve growth factor (NGF) synthesis/secretion by Schwann cells, we obtained Schwann cells from dorsal sensory ganglia of one-day old Wistar rats and cultured them with various concentrations of a mixed ganglioside comprising GM1, GD1a, GD1b, and GT1b. NGF synthesis was evaluated by the measurement of NGF concentration in the conditioned medium using an enzyme immunoassay. In the continuous presence of 10(-3) M gangliosides, the NGF concentration in the medium showed a four fold increase on the 4th day, and it then decreased by the 8th day. The present results indicate that gangliosides promote the production/synthesis of NGF by Schwann cells.
