Methods and compositions for enhanced delivery of macromolecules

摘要

The invention provides compositions and methods that enhance the delivery of large macromolecules (i.e., greater than 10 kDa), such as antigen-binding polypeptides, across tight junctions. Such methods and compositions are particularly useful for delivering therapeutic antigen-binding polypeptides to the CNS, via intranasal administration, for the treatment of neurological disorders.
