Researchers say they have safely delivered therapeutic agents into mammalian cells by attaching them to insect-derived peptides. The technique may help overcome the difficulties in getting vaccines and drugs into cells where they're needed. The Wistar Institute's Laszlo Otvos, Jr., and colleagues found that pyrrhocoricin, an antimicrobial peptide originally isolated from the European sap-sucking insect, Pyrrhocoris apterus, entered the cells without damaging them.
