Methods for diagnosing and treating CNS disorders by trans-blood-brain barrier delivery of protein compositions

摘要

The invention provides methods for treating or diagnosing CNS disorders by systemic administration of therapeutic or diagnostic protein compositions that are capable of crossing the blood-brain barrier, in some embodiments in both directions, while allowing their activity once across the barrier to remain substantially intact. The agents are transported across the blood-brain barrier via one or more endogenous receptor-mediated transport systems. Also provided are methods for manufacturing the compositions used in the methods described herein.
