BACKGROUND Protein transduction is safer than viral vector-mediated transduction for the delivery of a therapeutic protein into a cell. Fusion proteins with an arginine-rich cell-penetrating peptide have been produced in E. coli, but the low solubility of the fusion protein expressed in E. coli impedes the large-scale production of fusion proteins from E. coli. RESULTS Expressed protein ligat...

BACKGROUND Cell penetrating peptides have been successfully used to mediate the intracellular delivery of a wide variety of molecules of pharmacological interest. The main aim of the present work was to evaluate the potential of the S4(13)-PV cell penetrating peptide to mediate the intracellular delivery of plasmid DNA, aiming at its use in gene therapy applications. The S4(13)-PV cell penetrat...

Cell barriers are essential for the maintenance and regulation of the microenvironments of the human body. Cell-penetrating peptides have simplified the delivery of bioactive cargoes across the plasma membrane. Here, the passage of three cell-penetrating peptides (transportan, the transportan analogue transportan 10, and penetratin) across a Caco-2 human colon cancer cell layer in vitro was inv...

We report a simple, effective method to assess the cytosolic delivery efficiency and kinetics of cell-penetrating peptides using a pH-sensitive fluorescent probe, naphthofluorescein.
