| Outline of Final Research Achievements |
The biopharmaceuticals are required to permeate through blood-brain barrier (BBB) for achieving the efficient therapeutic effect in central nervous system (CNS). In this study, we therefore tried to develop the successful strategy for brain delivery of biopharmaceuticals via the direct nose-to-brain transport, which can bypass the BBB. The biopharmaceuticals coadministered intranasally with cell-penetrating peptides (CPPs) was efficiently delivered to the brain parenchyma including cerebral cortex and hippocampus, and eventually showed the therapeutic actions for CNS disorders. This study opened new avenues for developing a novel CNS pharmacotherapy with biopharmaceuticals.
