Serotonin increases glial cell line-derived neurotrophic factor release in rat C6 glioblastoma cells.

Hisaoka K, et al. Brain Res. 2004.

Abstract

Antidepressants, which increase monoamine levels, induce glial cell line-derived neurotrophic factor (GDNF) release in C6 cells. Thus, we examined whether monoamines affect on GDNF release in C6 cells. We found that serotonin (5-HT) specifically increased GDNF mRNA expression and GDNF release in a dose- and time-dependent manner. The 5-HT-induced GDNF release was mediated through the MEK/mitogen-activated protein kinase (MAPK) pathway and, at least, 5-HT(2A) receptors. The action of 5-HT on GDNF release may provide important insights into the mechanism of antidepressants.
