A number of different strategies for transporting nanocarriers across the BBB, such as conjugation to ApoE‐mimetic peptides, RVG peptides, and anti‐transferrin receptor antibodies, have been investigated by other groups,[42, 43, 44] and these may offer an opportunity to improve upon this therapeutic strategy for GBM in future work. The gene discussed is APOE; the disease is glioblastoma.
