mention is the transport of drugs/active pharmaceutical agents across the blood–brain
barrier (BBB). The epithelial-like tight junctions within the brain capillary endothelium hinder
the uptake of most pharmaceutical agents. With an aim to understand more deeply the
intricacies of cell-penetrating and targeted peptides as a powerful tool for desirable
biological activity, we provide a critical review of both CPP and homing/targeted peptides as …
