Objectives of our group Synthesis of Cell Penetrating Peptides (CPP) • Peptides deriving from protein transduction domain (Penetratin) • Polyarginine-based peptides CPP-containing polyplexes (covalent anchoring) CPP + polyplexes (mixtures) Selection and synthesis of Cell Interacting Peptides (CIP) • RGD-based peptides Increase membrane-cell interaction
