| Outline of Final Research Achievements |
The intranasally administered GLP-2 derivative containing cell-penetrating peptides and a penetration-accelerating sequence induced antidepressant-like effects in refractory depression model mice. Similarly, intranasally administered GLP-1, neuromedin U or oxytocin derivatives induced memory improving effects in amnesia model mice. These derivatives are probably delivered to the brain through the trigeminal nerve from the respiratory epithelium in the nasal mucosa. These results indicate that the derivatives may useful in the clinical treatment of psychiatric and neurological disorders by the intranasal administration.
