A research group led by Prof. Wu Aiguo at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in cooperation with Prof. Dan Larhammar's group at Uppsala University, has proposed a D-peptide ligand of neuropeptide Y receptor Y1, which can serve as nanocarriers to facilitate the traversal of the blood brain barrier (BBB) and thus targets gliomas efficiently. Results were published in Nano Today.
