Arginine-rich cell-penetrating peptides are short cationic peptides capable of traversing the plasma membranes of eukaryotic cells. While successful intracellular delivery of many biologically active macromolecules has been accomplished using these peptides, their mechanisms of cell entry are still under investigation. Recent dialogue has centered on a debate over the roles that direct transloc...
In addition to endocytosis-mediated cellular uptake, hydrophilic cell-penetrating peptides are able to traverse biological membranes in a non-endocytic mode termed transduction, resulting in immediate bioavailability. Here we analysed structural requirements for the non-endocytic uptake mode of arginine-rich cell-penetrating peptides, by a combination of live-cell microscopy, molecular dynamics...
In the presence of specialized proteins or peptides, a biological membrane can spontaneously restructure itself to allow communication between the intracellular and the extracellular sides. Examples of these proteins include cell-penetrating peptides and antimicrobial peptides (AMPs), which interact with cell membranes in complex ways. We briefly review cell-penetrating peptides and AMPs, and d...
A small library of oligoarginine peptides equipped with terminal cysteines was studied with respect to their cell-penetrating properties. The peptides themselves were inactive but gained the ability to enter cells upon extension of their sequence through disulfide bridge formation.
