Cell-penetrating peptides (CPPs) have served as vehicles for the delivery of different molecules and particles into cells. The efficiency and noninvasive nature of peptide-mediated cellular transduction provides a promising tool for biomedical research. Studies of cell-penetrating constructs that deliver oligonucleotides, peptides, and proteins have elucidated several important cellular signaling mechanisms. Here we briefly describe the major classes of cell-penetrating peptides. We also present various strategies used to couple different cargoes to CPPs.
