W

hether or not glia derived neurotophic factor (GDNF) has a role in disease mechanism of bipolar disorders has been a matter

of debate. Due to their role in regulation of synaptic plasticity in addition to survival and growth of neurons neurotophins

are important targets. Recent studies have pointed out that vitamin D can exert protective effects on nervous system by modulating

the synthesis of neurotrophins, calcium channels and calcium binding proteins. The expression of neurotrophic factors are regulated

via vitamin D in several cell types. Our previous study has showed that vitamin D receptor silencing showed similar effects with

beta amyloid treatment and up regulated L type voltage sensitive calcium channels alpha1 C (LVSCC A1C) and nerve growth factor

(NGF). These results might indicate the potential role of vitamin D- VDR pathway in neurodegeneration. The aim of this study

was to investigate the alterations in the level of GDNF release by 1,25-dihydroxyvitamin D

3

treatment in primary cortical neurons.

Cerebral cortex dissected from brains of Sprague Dawley rat embryos on the embryonic day 16 and cultured. GDNF levels released

to the culture medium were determined by ELISA. Our results showed that vitamin D treatment induced GDNF release to the

culture media. These results indicated that the GDNF expression might be regulated by vitamin D in cortical neurons and vitamin D

supplementation might be used as a tool for regulating neurotrophic factors in neurodegenerative disorders.
