Outline of Final Research Achievements

Based on the research implementation plan, I analyzed phosphorylation of dopamine- and cAMP-regulated phosphoprotein of 32 KDa (DARPP-32) which expressed especially in post synaptic cells. I treated mouse striatal slices for cannabinoid receptor agonist stimulation. Experiments were examined by western blotting methods using phospho specific antibody of DARPP-32 threonine 34 residue (Thr 34). The result is that DARPP-32 Thr 34 increase phosphorylation level by cannabinoid receptor agonist expectedly. I completed to generate cell culture for the expression of cannabinoid receptor. However, interaction between glutamate signaling to cannnbinoid is future plan of this work.
