| Outline of Final Research Achievements |
To overcome disorders caused by deficit of synapse maturation, such as autism, we attempted to promote synapse maturation using DREADD system. For this, we introduced one type of DREADD, hM3Dq, into layer II/III pyramidal neurons in cerebral cortex in mouse brains, followed by administration of CNO to induce hM3Dq signal. We found that the synapse maturation was promoted in the hM3Dq expressing neurons judged from the morphology of dendritic spines. Furthermore, we found that this signal induced serine phosphorylation in the cytoplasmic region of Neurexin-1 that was known to be involved in synapse maturation, due to the activation of PKC.
