Size-dependent brain distribution of macromolecular drug delivery platform
The blood brain barrier (BBB) is a specialized endothelium that prevents the uptake of substances from the systemic circulation into the central nervous system. This barrier, while protecting the sensitive physiological environment of the brain, is also a major impediment in administering therapeutics that need to pass through the BBB. A drug delivery platform that could deliver therapeutic agents directly to the brain is needed, and could have wide ranging significance in a variety of psychiatric, oncology, infectious, and neurodegenerative diseases.
