| Outline of Final Research Achievements |
We developed a superresolution imaging platform for microscopic analysis of synaptic molecules in the brain of psychiatric model animals. We optimized optical systems and experimental conditions for the fluorescence labeling of brain slices of model animals for STORM imaging. We also developed software for analyzing distribution of synaptic molecules in STORM images. STORM analysis of various regions of brain of the model mouse revealed the change in size and number of nanoclusters formed by dopamine receptors in striatum nucleus accumbens of DISC1 knockout mice. We confirmed that alteration of D2R nanoclusters in DISC1 knockout mice was improveed by administration of antipsychotic clozapine.
