Outline of Final Research Achievements

Antibody drugs have increasingly occupied a high share of the global pharmaceutical market in the past decade. Brain-targeted antibody drugs and macromolecular drugs are expected to be next generation biodrugs to have direct effects on brain tumors and neurodegenerative diseases such as Alzheimer's disease. However, so far, many of brain-targeted antibody drugs have resulted in clinical trial failures, possibly due to the inefficiency of CNS delivery by systemic injection and the difficulties of crossing the blood-brain barrier. In the present study, to realize noninvasive, highly efficient and target-specific delivery of macromolecular drugs to the CNS, a new in vivo screening method based on directed evolution was established in mice.
