Abstract

The recent discovery of new potent therapeutic molecules which do not reach the clinic due to poor delivery and low bioavailability have made of delivery a key stone in therapeutic development. Several technologies have been designed to improve cellular uptake of therapeutic molecules, including cell-penetrating peptides (CPPs), which have been successfully applied for in vivo delivery of biomolecules and constitute very promising tools. Distinct families of CPPs have been described; some require chemical linkage between the drug and the carrier for cellular drug internalization while others like Pep-and MPG-families, form stable complexes with drugs depending on their chemical nature. Pep and MPG are short amphipathic peptides, which form stable nanoparticles with proteins and nucleic acids respectively. MPG and Pep based nanoparticles enter cells independently of the endosomal pathway and efficiently deliver cargoes in a fully biologically active form into a large variety of cell lines as well as in animal models. This review will focus on the mechanisms of non-covalent MPG and Pep-1 strategies and their applications in cultured cells and animal models.
