delivery systems for the brain. Polypeptide nanocarriers are versatile platforms and combine
high functionality with good biocompatibility and biodegradability. The key to the efficient
brain delivery of NPs is the specific targeting of cerebral endothelial cells that form the blood–
brain barrier (BBB). We have previously discovered that the combination of two different
ligands of BBB nutrient transporters, alanine and glutathione, increases the permeability of …
