PG - 113-8 AB - Brain-derived neurotrophic factor (BDNF) and S100beta stimulate serotonergic neurons in fetal rat raphe primary cultures grown under serum-free conditions. BDNF (50 ng/ml) treatment for 3 h enhanced S100beta immunoreactivity in both raphe and hippocampal glial cells. Combined treatment with BDNF and S100beta for 3 days increased the soma area of 5-HT neurons, but not the neurite length. Our results suggest that BDNF and S100beta, which regulate different signal transduction cascades, interact to exert complimentary effects on neuronal maturation by acting sequentially, not concurrently.
