Specific changes in c-fos expression and colocalization with DNA in identified neuronal nuclei of edible snail following neurotransmitter application

摘要

The effects of serotonin and glutamate on c-fos expression and c-Fos colocalization with DNA were immunohistochemically studied in defense behavior command neurons R-LPa2-3 in snail Helix lucorum. Simultaneous neurotransmitter application resulted in increased c-Fosimmunoreactivity and colocalization with DNA-specific stain Hoechst 33342 in LPa2 and RPa2 neurons with specific dynamics for each identified cell. In the nuclei of LPa3 and RPa3 neurons, neurotransmitter application did not significant change the c-Fos level. These findings are indicative of specific spatiotemporal changes in c-fos expression and c-Fos colocalization with DNA in investigated neurons of edible snail under the influence of neurotransmitters.
